The climate of Argentina is a complex subject: the country's vast size and considerable variation in altitude make for a wide range of climate types. Many regions have different, often contrasting, microclimates. In general, northern parts of the country are characterized by hot, humid, rainy summers and mild winters with periodic droughts. The center of the country has hot summers with occasional tornadoes and thunderstorms, and cool, dry winters. The southern part of the country has a dry climate with warm summers and cold winters. High elevations at all latitudes experience cooler conditions, and the mountainous zones can see heavy snowfall. Argentina has four seasons: winter (June–August), spring (September–November), summer (December–February) and autumn (March–May), all featuring different weather conditions.

The hottest and coldest temperature extremes recorded in South America have occurred in Argentina.[3] The highest recorded temperature is 48.9 °C (120.0 °F) in Rivadavia, Salta Province, on December 11, 1905, while the lowest temperature recorded is −32.8 °C (−27.0 °F) at Sarmiento, Chubut, on June 1, 1907.[3]

The geographic and geomorphic characteristics of Argentina tend to create extreme weather conditions, often leading to natural disasters that negatively impact the country both economically and socially. The Pampas, where many of the large cities are located, has a flat topography and poor water drainage, making it vulnerable to flooding. Severe storms can lead to tornadoes, damaging hail, storm surges, and high winds, causing extensive damage to houses and infrastructure, displacing thousands of people and causing significant loss of life. Extreme temperature events such as heat waves and cold waves impact rural and urban areas by negatively impacting agriculture, one of the main economic activities of the country, and by increasing energy demand, which can lead to energy shortages.

Argentina is vulnerable and will be significantly impacted by climate change. Temperatures have increased in the last century while the observed changes in precipitation are variable, with some areas receiving more and other areas receiving less. These changes have impacted river flow, increased the frequency of extreme weather events, and led to the retreat of glaciers. Based on the projections for both precipitation and temperatures, these climatic events are likely to increase in severity and create new problems associated with climate change in the country.

Seasons[edit]

Winter[edit]

In winter (June–August), the northern parts of Argentina are generally warm, the center parts mild, and the southern parts cold with frequent frost and snow.[4] The southern parts of the country are influenced by the ocean, resulting in cold weather that is less intense and prolonged than at comparable latitudes in the northern hemisphere.[4] The northern parts of the country have the warmest temperatures, with an average of 14 °C (57.2 °F) while the central parts are cooler, with an average of 10 °C (50.0 °F).[5] In the extreme south, mean temperatures are below 4 °C (39.2 °F). At higher altitudes in the Andes, average winter temperatures are below 0 °C (32.0 °F).[5] June and July temperatures are normally similar to each other while August temperatures are normally higher than in June and July by about 2 °C (3.6 °F).[5]

Precipitation varies widely during the winter months. Northern parts of the country, particularly the extreme northern part of the littoral region and northwestern parts of Patagonia, receive the most precipitation during the winter months, with mean winter precipitation exceeding 250 mm (9.8 in).[5] In much of the humid Pampas, average precipitation is between 75 to 200 mm (3.0 to 7.9 in) while in the north, in areas bordering the Andes, it averages less than 10 mm (0.39 in).[5]

Spring[edit]

Spring (September–November) is similar to fall, with mild days and cool nights. During mid-October a large variety of wild and urban flora are in bloom. Temperatures range from 20 °C (68.0 °F) in the north to 14 °C (57.2 °F) in the center, and 8 to 14 °C (46.4 to 57.2 °F) in much of Patagonia.[6] Tierra del Fuego and the higher altitudes of the Andes have the coolest springs, with mean temperatures below 8 °C (46.4 °F).[6] Temperatures become warmer as spring progresses.[6]

During spring, precipitation in the country varies, with the greatest amounts being in northern Buenos Aires province and the Littoral region, where the average precipitation exceeds 250 mm (9.8 in).[6] Arid regions (Arid Diagonal) have the lowest spring precipitation, with an average precipitation of less than 50 mm (2.0 in).[6]

Summer[edit]

In summer (December–February), temperatures range from an average of 26 °C (78.8 °F) in the north to a mean of 20 °C (68.0 °F) in the center of the country except for the southeastern parts of Buenos Aires province, where temperatures are cooler in the summer, owing to the maritime influence.[2][7] In the extreme south of the country, the temperature averages 12 °C (53.6 °F); at very high altitudes, the average is below 10 °C (50.0 °F).[7]

During the summer months, mean precipitation varies throughout the country: the eastern parts of Salta province, Jujuy province, northern Tucumán Province and all of Misiones province are the wettest locations,[7] receiving more than 400 mm (16 in) of precipitation during the season.[8] In much of the Littoral region and most of Buenos Aires province, mean summer precipitation ranges from 200 to 300 mm (7.9 to 11.8 in).[7] The Patagonia region is dry, with much lower precipitation than the rest of the country, averaging less than 50 mm (2.0 in) and occasionally less than 25 mm (0.98 in);[7][8] Patagonia receives between 10 to 25 mm (0.39 to 0.98 in) of precipitation each month.[8] In the central and northern parts of the country, January is usually the wettest month, with an average monthly precipitation of 100 mm (3.9 in) in most places, but exceeding 200 mm (7.9 in) in some places.[8]

Autumn[edit]

Autumn (March–May) is generally mild. Some forests and vineyards display autumn foliage, with their red and orange leaves, especially in mid-April. Frost arrives noticeably earlier in the south and later in the north. Mean temperatures can exceed 22 °C (71.6 °F) in the northern parts of the country to 16 °C (60.8 °F) in much of the central parts of the country, and less than 6 °C (42.8 °F) at the higher altitudes.[9] As autumn progresses, mean temperatures fall in all regions, with March being warmer than May.[10] In the north, mean temperatures range from 24 °C (75.2 °F) in March to 18 °C (64.4 °F) in May. In the central parts of the country, mean temperatures in March are between 18 to 22 °C (64.4 to 71.6 °F), dropping to 10 to 14 °C (50.0 to 57.2 °F) in May.[10] The mean temperature in Tierra del Fuego in the extreme south is 10 °C (50.0 °F), and occasionally lower.[10]

Precipitation is highest in northeast Argentina and lowest in the Patagonia and Cuyo regions.[9] In northeast Argentina, mean precipitation can exceed 400 mm (16 in) while in most of Buenos Aires Province and northwest Argentina, mean autumn precipitation ranges between 200 to 500 mm (7.9 to 19.7 in).[9][10] In much of the western parts of northwest Argentina and the Patagonia (except for western Patagonia where precipitation is higher, averaging 100 to 200 mm (3.9 to 7.9 in)) and Cuyo regions, precipitation can average less than 50 mm (2.0 in).[9] In the northwest, precipitation decreases as autumn progresses, ushering in the dry season.[10] For example, in Tucuman province, March averages more than 200 mm (7.9 in) of precipitation while May averages less than 50 mm (2.0 in).[10] In contrast, precipitation increases in Patagonia, particularly in the western parts where May precipitation can exceed 100 mm (3.9 in).[10]

Regional climate[edit]

Argentina possesses a wide variety of climatic regions ranging from subtropical in the north to subantarctic in the far south. Lying between those is the Pampas region, which features a mild and humid climate.[11][12] As to be expected with that range of climates, there is a wide variety of biomes in the country, including subtropical rain forests, semi-arid and arid regions, temperate plains in the Pampas, and cold subantarctic in the south.[13] However, despite the diversity of biomes, about two-thirds of Argentina is arid or semi-arid.[13][14] In general, Argentina has four main climate types: warm, moderate, arid, and cold, all determined by the expanse across latitude, range in altitude, and relief features.[2] Mean annual temperatures range from 5 °C (41.0 °F) in the far south to 25 °C (77.0 °F) in the north.[12] Also, because of the narrowness of the South American continent, the nation's climate is influenced by the Andes mountain chain along its western border and maritime influences from the Atlantic Ocean.[15]

Mesopotamia[edit]

Mesopotamia has a subtropical climate with no dry season.[2] Under the Köppen climate classification, it has a humid subtropical climate (Cfa).[16] The main features of the climate are high temperatures and abundant rainfall throughout the year;[2] this abundant rainfall makes water scarcity and extended periods of drought uncommon; much of the region has a positive water balance.[16][17][18]:85

Average annual precipitation ranges from less than 1,000 mm (39 in) in the southern parts of the province to approximately 1,800 mm (71 in) in the eastern parts.[16][18]:30 Precipitation is slightly higher in the summer than in the winter and generally decreases from east to west and from north to south.[17][18]:32[19] Summer (December–February) is the most humid season, ranging from a low of 300 mm (12 in) to a high of 450 mm (18 in).[18]:37 In this season, most rain falls during convective thunderstorms.[18]:38 Fall (March–May) is one of the rainiest seasons, with many places receiving over 350 mm (14 in).[18]:38 As in summer, precipitation falls mainly during convective thunderstorms.[18]:39 Winter (June–August) is the driest season, with precipitation ranging from less than 40 mm (1.6 in) in the west to over 340 mm (13 in) in the east.[18]:39 Most of the precipitation during winter comes from frontal systems,[18]:40 particularly the sudestada, bringing long periods of rain, cloudiness, cooler temperatures, and strong winds.[19][20][21][22] Spring (September–November) is similar to fall, with a mean precipitation of 340 mm (13 in).[18]:40

As a whole, the region has high temperatures throughout the year.[2] Summers are very hot and humid while winters are mild to warm.[15][16][19] The northern parts of the region are warmer than the southern parts.[19] During heat waves, temperatures can exceed 40 °C (104.0 °F) in the summer months, while in the winter months, cold air masses from the south can push temperatures below freezing, resulting in frost.[20][21][23] However, such cold fronts are brief and are less intense than areas further south or at higher altitudes.[20][21][23] Snowfall is extremely rare and mainly confined to the uplands of Misiones Province, where the last significant snowfall occurred in 1975 in Bernardo de Irigoyen.[23][24]

Chaco[edit]

Picture of the western parts of the region, which are characterized by shrubs and low to medium forest cover
Western parts of the region are characterized by shrubs and low to medium forest cover due to lower precipitation.[13][16]

The Chaco region in the center-north has a subtropical climate with hot, humid summers and mild, dry winters.[19][25] Under the Köppen climate classification, the west has a semi-arid climate (Bs)[16] while the east has a humid subtropical climate (Cfa).[26][27]:486 Chaco is one of the few natural regions in the world located between tropical and temperate latitudes that is not a desert.[27]:486 Precipitation and temperature are relatively homogeneous throughout the region.[27]:486

Mean annual precipitation ranges from 1,200 mm (47 in) in the eastern parts of Formosa Province to a low of 450 to 500 mm (18 to 20 in) in the west and southwest.[16][18]:30 Most precipitation falls in the summer.[16][19] Summer rains are intense, and torrential rain is common, occasionally causing floods and soil erosion.[26][28] During the winter months, precipitation is sparse.[16][19] Eastern areas receive more precipitation than western areas since they are more influenced by moist air from the Atlantic Ocean, which penetrates the eastern areas more than the west, bringing in more precipitation.[16] As a result, the vegetation differs: eastern areas are covered by forests, savannas, marshes and subtropical wet forest, and western areas are dominated by medium and low forests of mesophytic and xerophytic trees and a dense understory of shrubs and grasses.[13] In all parts of the region, precipitation is highly variable from year to year.[29]

The Chaco region is the hottest in Argentina, with a mean annual temperature of 23 °C (73.4 °F).[16] With mean summer temperatures occasionally reaching 28 °C (82.4 °F), the region has the hottest summers in the country.[16][18]:63 Winters are mild and brief, with mean temperatures in July ranging from 16 °C (60.8 °F) in the northern parts to 14 °C (57.2 °F) in the southernmost parts.[30]:1 Temperatures can reach as high has 49 °C (120.2 °F) in summer, and during cold waves can fall to −6 °C (21.2 °F).[16]

Northwest[edit]

The Altiplano is characterized by a cold, arid but sunny climate with large diurnal ranges.

Northwest Argentina is predominantly dry, hot, and subtropical.[31] Owing to its rugged and varied topography, the region is climatically diverse, depending on the altitude, temperature and distribution of precipitation.[32] Consequently, the vegetation will also differ.[33] Under the Köppen climate classification, the region has five different climate types: semi–arid (BS), arid (BW), temperate without a dry season and temperate with a dry season (Cf and CW respectively), and, at the highest altitudes, an alpine.[33]

Precipitation is highly seasonal and mostly concentrated in the summer months.[33][34] It is distributed irregularly owing to the country's topography although it generally decreases from east to west.[33][35]:29 The eastern slopes of the mountains receives between 1,000 to 1,500 mm (39 to 59 in) of precipitation a year, though some places receive up to 2,500 mm (98 in) annually owing to orographic precipitation.[32][33] The high rainfall on these first slopes creates a thick jungle that extends in a narrow strip along these ranges.[36] The temperate valleys, the location of major cities such as Salta and Jujuy,[note 2] have an average precipitation ranging between 500 to 1,000 mm (20 to 39 in),[37] with rainfall mainly concentrated in the summer months, often falling in short but heavy bursts.[38][39] Valleys in the southern parts of the region are drier than valleys in the north due to the greater height of the Andes and the Sierras Pampeanas on the eastern slopes compared to the mountains in the north, presenting a significant orographic barrier that blocks moist winds from the Atlantic and Pacific oceans.[35]:22–23[40]:28 These valleys receive less than 200 mm (7.9 in) of precipitation per year and are characterized by sparse vegetation adapted to the arid climate.[36] The area further west in the Puna region, with an average altitude of 3,900 m (12,800 ft), is mostly a desert due to the blocking of the easterly winds by the Andes and the northwest extension of the Sierras Pampeanas.[32][35]:33[36][41] Precipitation in the Puna region averages less than 200 mm (7.9 in) a year while high isolation, strong winds, and low humidity exacerbate the dry conditions.[13][42]

Temperatures in northwest Argentina vary by altitude.[32] The temperate valleys have a temperate climate, with mild summers and dry and cool winters with regular frosts.[38][43]:53In the Quebrada de Humahuaca valley, mean annual temperatures range from 12.0 to 14.1 °C (53.6 to 57.4 °F), depending on altitude.[44]:10 In the Calchaquí Valleys in Salta province, the climate is temperate and arid with large thermal amplitudes, long summers, and a long frost-free period.[44]:10[45][46] In the valleys in the south in La Rioja and Catamarca provinces and the southwest parts of Santiago del Estero Province, which is part of the arid Chaco ecoregion,[47] temperatures during the summer are very high, averaging 26 °C (78.8 °F) in January while winters are mild, averaging 12 °C (53.6 °F).[47] Cold fronts from the south bringing cold Antarctic air can cause severe frosts in the valleys of La Rioja and Catamarca provinces.[40]:33 In contrast, the Zonda wind, which occurs more often during the winter months, can raise temperatures up to 35 °C (95.0 °F) with strong gusts, sometimes causing crop damage.[40]:33–34 Temperatures in the Puna region are much colder, with a mean annual temperature of less than 10 °C (50.0 °F) owing to the high altitude.[13] The Puna region is characterized by being cold with a large diurnal range but sunny throughout the year.[42][44]:17

Cuyo[edit]

Much of the Cuyo region is dry, depending on rivers for irrigation

The region of Cuyo has an arid climate or a semi-arid climate.[48][49] The region's wide range in latitude, combined with altitudes ranging from 500 m (1,600 ft) to nearly 7,000 m (23,000 ft), means that it has a variety of different climate types.[46][49] In general, most of the region has a temperate climate, with valleys at higher altitudes having a milder climate.[45] At the highest altitudes (over 4,000 m (13,000 ft)), icy conditions persist year round.[49]

Average annual precipitation ranges from 100 to 500 mm (3.9 to 19.7 in), though it is generally unpredictable.[48][49] More than 85% of annual rainfall occurs from October to March, which constitutes the warm season.[48] In contrast, the winter months are dry.[50] Eastern and southeastern areas of the region receive more precipitation than the western areas since they receive more summer rainfall.[50] Precipitation is highly variable from year to year and appears to follow a cycle between dry and wet years in periods of about 2, 4–5, 6–8, and 16–22 years.[48] In wet years, easterly winds caused by the subtropical South Atlantic anticyclone are stronger, causing moisture to flow towards this region; during dry years, these winds are weaker.[48][50]

Summers in the region are hot and generally sunny; winters are dry and cold.[4][51] Since this region has a wide range of altitudes, ranging from 500 m (1,600 ft) to nearly 7,000 m (23,000 ft), temperatures can vary widely. The Sierras Pampeanas, which cross into both San Juan province and San Luis province, have a milder climate with mean annual temperatures ranging from 12 to 18 °C (53.6 to 64.4 °F).[52] Throughout the region, the diurnal range is great, with very high temperatures during the day followed by cold nights.[51] In all locations, at altitudes over 3,800 m (12,500 ft), permafrost is present; icy conditions persist year round at altitudes over 4,000 m (13,000 ft).[49]

The Zonda, a Foehn wind characterized by warm, dry air, can cause temperatures to exceed 30 °C (86.0 °F) and occasionally 45 °C (113.0 °F), as occurred in 2003.[53][54] However, cold waves are also common, caused by the channeling by the Andes of cold air from the south, making for frequent cold fronts during the winter months and bringing temperatures that can fall below freezing,[55][56] and occasionally below −10 to −30 °C (14.0 to −22.0 °F) at higher altitudes.[57]

Pampas[edit]

Picture showing the landscape of the Pampas which is mostly a flat grassland
Pampas landscape

The Pampas region has land that is appropriate for agriculture and raising livestock. It is a mostly flat area, interrupted only by the Tandil and Ventana sierras in its southern portion.[58] The climate of the Pampas is characterized as temperate and humid with no dry season, featuring hot summers and mild winters (Cfa/Cfb according to the Köppen climate classification).[58][59][60] The weather in the Pampas is variable due to the contrasting air masses and frontal storms that impact the region.[61] Annual temperatures range from 17 °C (62.6 °F) in the north to 14 °C (57.2 °F) in the south.[59] Precipitation increases as one moves east[62] and ranges from under 500 mm (20 in) in the south and west to 1,200 mm (47 in) in the northeast.[63] Precipitation is fairly evenly distributed throughout the year in the easternmost parts of the Pampas; in the western parts, most of the precipitation is concentrated during the summer months, and winters are drier.[58][12] The Pampas are influenced by the El Niño Southern Oscillation, which is responsible for variation in annual precipitation.[58][63] An El Niño year leads to higher precipitation while a La Niña year leads to lower precipitation.[63]

Summers in the Pampas are hot and humid with coastal areas being modified by the cold Malvinas Current.[61] Afternoon thunderstorms, which can bring intense amounts of precipitation, are common, as are heat waves that can bring temperatures in the 36 to 40 °C (96.8 to 104.0 °F) range for a few days.[63] These thunderstorms are known to have the most frequent lightning and highest convective cloud tops in the world.[64][65] The severe thunderstorms produce intense hailstorms, floods, including flash floods, as well as the most consistently active tornado region outside the central and southeastern US.[66] These are usually followed a day or two of strong Pampero winds from the south, which bring cool, dry air.[63] Precipitation in the summer is high, with monthly amounts averaging between 90 mm (3.5 in) and 160 mm (6.3 in) in most places.[15][67]

Autumn arrives in March and brings periods of very rainy weather followed by dry, mild stretches and cool nights.[63] Some places in the east receive rainfall throughout autumn whereas in the west, after the rains, the weather quickly becomes very dry.[63] Generally, frost arrives in early April in the southernmost areas, in late May in the north, and ends by mid-September, although the dates of the first and last frosts can vary from year to year.[58][59][63] Frost is rarely intense or prolonged and may not occur each year.[4][24]

Winters are mild with frequent frosts and cold spells.[61] Temperatures are usually mild during the day and cold during the night.[60] Most precipitation results from frontal systems associated with cyclogenesis and strong southeasterly winds (Sudestada), which bring long periods of precipitation, cloudiness and cooler temperatures, particularly in the southern and eastern parts.[24][68][22] Dull, gray and damp weather characterize winters in the Pampas.[24] Occasionally, tropical air masses from the north may move southward, providing relief from the cool, damp temperatures.[24] Snowfall is extremely rare. When it does snow, it usually lasts for only a day or two.[24]

Patagonia[edit]

Picture showing a windswept tree owing to the strong winds
The Patagonian climate is characterized by strong, persistent winds from the west year round,[69][70] forming characteristic Flag trees.

The Patagonian climate is classified as arid to semi-arid and temperate to cool temperate.[71][72] One defining characteristic are the strong winds from the west which blow year round (stronger in summer than in winter), which favors evaporation and is a factor in making the region mostly arid.[73] There are three major factors that influence the climate of the region: the Andes, the South Pacific High and South Atlantic High, and an isolation that is more pronounced in eastern than western areas.[74]

The north–south orientation of the Andes creates a barrier for humid air masses coming from the Pacific Ocean, forming an extensive rain shadow[72][75] and causing most of the region to be arid.[75][73] South of 52°S, the Andes are lower in elevation, reducing the rain shadow effect in Tierra del Fuego province and allowing forests to thrive on the Atlantic coast.[70] Patagonia is located between the subtropical high pressure belt and the subpolar low pressure zone, meaning it is exposed to westerly winds that are strong, since south of 40°S there is little land to block these winds.[69][70] Because Patagonia is located between the semi-permanent anticyclones of the Pacific Ocean and the Atlantic Ocean at around 30°S, and the subpolar low at around 60°S, the movement of the high and low pressure systems along with ocean currents determine the precipitation pattern.[72]

The influence of the Pacific Ocean, general circulation patterns, and the topographic barrier caused by the Andes results in a strong precipitation gradient,[72] one of the strongest in the world.[76] Precipitation steeply decreases from west to east,[75][76] ranging from 4,000 mm (160 in) in the west on the Andean foothills at 41°S to 150 mm (5.9 in) in the central plateaus.[75] The high precipitation in the Andes in this region allows forests to thrive as well as glaciers and permanent snowfields.[62][77][4] Most of the region receives less than 200 mm (7.9 in) of precipitation per year.[73] The aridity of the region is due to the combination of low precipitation, strong winds, and high temperatures in the summer months, all of which cause high evaporation rates.[13] In most of Patagonia, precipitation is concentrated in the winter months, except for the northeastern and southern parts, where precipitation is more evenly distributed.[72][78][73] Thunderstorms are infrequent, occurring only during summer.[73] Snowfall occurs mainly in the west and south, which can result in strong snowstorms.[2][13]

Patagonia's temperatures are relatively cold for its latitude due to the cold Malvinas Current and the high altitude.[73] A characteristic of the temperature pattern is the NW–SE distribution of isotherms due to the presence of the Andes.[72] The warmest parts of the region are in northern parts of Rio Negro province and Neuquén province, where mean annual temperatures range from 13 to 15 °C (55.4 to 59.0 °F), while the coldest are in western Santa Cruz province and Tierra del Fuego province, where mean temperatures range from 5 to 8 °C (41.0 to 46.4 °F).[73] At higher altitudes in the Andes stretching from Neuquén province to Tierra del Fuego province, mean annual temperatures are below 5 °C (41.0 °F).[73] Strong westerly winds can decrease the perception of temperature (wind chill), particularly in summer.[72] The annual range of temperatures in Patagonia is lower than at similar latitudes in the Northern Hemisphere owing to the narrowness of the region at higher latitudes and the stronger maritime influence.[72][79]

Extremes[edit]

Lago Frías in Río Negro Province during winter. It is considered to be the wettest place in Argentina.[97]

High[edit]

According to the World Meteorological Organization, the highest temperature recorded in Argentina is 48.9 °C (120.0 °F) in Rivadavia, Salta, Salta Province on December 11, 1905.[3]

Low[edit]

The lowest temperature recorded in South America and Argentina is −32.8 °C (−27.0 °F) in Sarmiento on June 1, 1907.[3]

Precipitation[edit]

With an average annual precipitation of 3,668 mm (144.4 in), Lago Frías in Río Negro Province is considered to be the wettest place in Argentina.[98] Although an average annual precipitation of 6,251 mm (246.1 in) has been recorded in Lago Tromen in Neuquén province, the validity of the data is dubious owing to fewer years of data.[98] Lago Frías also has the record for wettest monthly precipitation in Argentina: 1,147 mm (45.2 in) of precipitation was recorded in May 1951.[97] In contrast, the driest place is Angualasto, San Juan province, which only receives 24 mm (0.94 in) of precipitation a year.[98] The highest recorded one-day rainfall total occurred on April 2, 2013, when 392.2 mm (15.44 in) of rain fell in La Plata at the La Plata Astronomical Observatory,[99] causing massive flooding and power outages.[100]

Natural disasters[edit]

Natural disasters can negatively impact the environment, infrastructure and essential services.[101]:37 For reasons directly related to its geography, Argentina often experiences natural disasters such as severe storms, flooding, and droughts.[101]:37

Floods[edit]

Picture showing the Pampas being flooded
The Pampas are vulnerable to flooding owing to their flat topography and poor water drainage.

Argentina's geomorphic characteristics make the country highly vulnerable to floods.[102] These floods can damage infrastructure, cause loss of life, increase the risk of diseases, and negatively impact agricultural productivity, which is one of the main economic activities of the country.[103][104] Many of the large Argentinean cities and agriculturally productive areas lie near rivers.[102] The plains are at highest risk for flooding, particularly in the northeastern and central parts of the country, including Greater Buenos Aires.[103] This is because these plains, which cover 35% of the land area in the country (including the Chaco and Pampean areas), are characterized by a flat landscape, which can impede proper water drainage.[105] Both the Parana and Paraguay basins have a flat landscape and are thus highly susceptible to flooding due to river overflows following high rainfall.[14] These floods can last for months, particularly in the Parana River, owing to its large basin.[14] In the most extreme case, during the year 1982–1983, the floods in the Parana River persisted for more than a year, negatively impacting the area both socially and economically.[106] Major flooding events in the Parana River include those of 1992 and 1997 and have been more frequent since the 1980s due to higher precipitation trends.[14] Similarly, in Buenos Aires Province, flooding occurs due to river overflows and poor water drainage; major flooding events in the province occurred in 1987, 2002/2003, 2012 and in 2014, causing damage to agriculture production.[14] Most of the flooding events occur in El Niño years owing to higher rainfall.[101]:38 Flooding can also affect Patagonia and urban centers in the northwest, but the number of people affected and economic losses are lower than those in the Pampas owing to lower population densities.[107] Flooding can jeopardize access to safe water.[108] A leptospirosis outbreak occurred following a flood in 1998.[108]

Droughts and dust storms[edit]

Argentina is highly dependent on water supplies originating outside its borders, making it highly vulnerable to changes in water supply due to climate change.[109] Droughts are frequent and devastating.[110] Several years of droughts during the last decade have severely affected agricultural production and reduced economic growth.[109][111] A drought in 2009 was the worst drought in more than 50 years.[112] Many cattle died of hunger, and huge swaths of soy, corn and wheat fields were affected.[112] It was estimated that the country lost more than US$5 billion from the drought.[112] A drought in 2011 affected farming of soy and corn, causing losses of US$2.5 billion.[101]

Drier parts of the country are highly prone to dust storms.[114] These include areas west of Buenos Aires, which can average more than eight dust storms per year, and parts of Patagonia, owing to its aridity and windy climate.[115] Certain areas in the Altiplano are also highly prone to dust storms owing to extensive areas of closed depressions and the presence of salt flats that erode the rock, which becomes a source of fine material that can travel large distances during periods of strong wind.[114][115] Dust storms are more frequent during droughts, particularly in agricultural areas.[114] Dust storms can effect large areas, leading to numerous impacts.[113] These dust storms can lead to loss of crop and livestock, affecting the local economy.[113] Productive topsoil may be lost during dust storms, leading to loss in soil productivity, which can increase soil erosion and negatively affect crop productivity in the long term.[113] In addition to the impact on agriculture, dust storms can damage cars and buildings, lower visibility on roads, affect air quality, and affect water quality in rivers and lakes.[113]

Tornados and severe storms[edit]

Argentina experiences frequent tornadoes each year.[116] Tornadoes occur in the South American "tornado alley"[66] (Spanish: Pasillo de los Tornados), which includes the provinces of Entre Ríos, Córdoba, Santa Fe, La Pampa and Greater Buenos Aires.[117] The frequency of tornadoes is similar to the one found in Tornado Alley in North America.[118] However, there is no exact number of tornado occurrences per year, owing to the lack of data.[118][119] These regions have the most frequent and intense Mesoscale convective systems.[66] Tornadoes occur between November and April.[119] In this region, which occupies most of the Pampas, cold air from Patagonia meets warm, humid air from Brazil with dry air coming from the Andes.[119] When these air masses collide, they can produce intense storms, frequently becoming supercells that can produce tornadoes.[119] With a larger number of convective storms, there is a higher chance that some of these storms will produce tornadoes.[116] Most tornadoes are relatively weak and rarely cause deaths.[117] The strongest tornado recorded in Argentina occurred in 1973 when a tornado struck San Justo, Santa Fe.[119] The tornado was an F5 on the Fujita scale, with winds up to 500 km/h (310 mph), making it the worst tornado in Latin America and the Caribbean.[119]

Severe storms impact large cities more often and can damage cars, houses and disrupt public services such as transportation and collection and disposal of urban solid waste.[101]:39 The foothills of the Andes and the Sierras de Cordoba are vulnerable to hail.[66] This is because the Andes force humid air from the Atlantic upwards,[120] intensifying the updrafts within thunderstorms, making hail more likely.[121] Mendoza, a city located in the Andean foothills, experiences frequent hailstorms that can impact the agriculture of the region.[66] Hailstorms have caused serious losses in both urban and rural areas.[120] It is estimated that wine and fruit production experience yearly losses of US$50 million and US$30 million, respectively, due to hail.[120] Most of these hailstorms occur in the summer although they can occur in winter, particularly in the east where warm and humid air from the north frequently collides with cold air from the south, leading to convective thunderstorms that can produce hail.[120]

Storm surges caused by extratropical cyclones have been recorded along the coastal areas.[122] These storm surges are formed from strong winds that blow towards the land.[123] They are formed due to the interaction between the semi-permanent South Pacific High and a low pressure system over the Atlantic, southeast of Argentina, creating strong winds from the south or southwest.[122] The sudestada ("Southeasters"), which brings the worst storm surges, occurs when there is a high pressure system over southern Argentina in the adjacent ocean that interacts with a low pressure over Uruguay and southern Brazil, causing strong winds from the southeast.[22][124] Storm surges have caused flooding of coastal areas, leading to extensive property loss and other damage.[124][125] It is also the main natural factor in the erosion of coastlines.[125] The flooding as a result of storm surges are particularly destructive in flat coastal areas such as the Rio de La Plata shores, and the Salado Basin.[124]

Snowstorms and cold waves[edit]

Argentina regularly receives cold air from the south that can reach low latitudes owing to the influence of the Andes.[126] Cold waves are usually accompanied with severe snowstorms or extremely cold conditions that can have a devastating impact on the country's economy.[126] These snowstorms and/or extremely cold conditions can partially or completely paralyze activities in large areas of Patagonia and the center of the country.[15]:12 In addition, cold conditions can lead to energy shortages during the winter months due to increased demand.[126] The low temperatures brought by these cold waves can cause frosts that can damage plants, severely affecting agricultural production and devastating the local economy.[127]

Climate change[edit]

Climate change is predicted to have a significant effect on the climate of Argentina.[128]:30 There has been an increase in annual precipitation in almost all of Argentina, particularly in the northeast and the center of the country, expanding agricultural production to the west in areas that were previously too dry.[15]:24[128]:29[129]:87 In contrast, the Andean part of Patagonia, along with the Cuyo region, has seen a decrease in precipitation, leading to a reduction in river flow in the last 100 years.[130]:15 These trends were observed with an increase in the river–stream flows in most of the country, excluding rivers originating from the Andes, and an increase in extreme precipitation events that led to considerable socioeconomic losses.[129]:25,87 The increase in precipitation has led to more variability in precipitation from year to year in the northern parts of the country, with a higher risk of prolonged droughts.[129]:88

Mean temperatures have increased by 0.5 °C (0.90 °F) between 1901 and 2012, slightly lower than the global average.[14] Temperatures in the Andean part of Patagonia have increased by more than 1 °C (1.80 °F), which has caused the retreat of almost all of the glaciers.[128]:30[129]:25 This is affecting water availability to the arid areas of the country that depend on glacier meltwater.[131] Higher temperatures can reduce winter snowfall, causing river flow to decrease, which in turn can reduce hydroelectric energy production; losses of up to 40% have been observed.[129]:25 In the last half of the 20th century, the lack of snow in the highest peaks in the Cuyo region has impacted agriculture and viticulture production due to the decrease in available water in the rivers.[132] Outside of Patagonia, mean temperatures have increased at a slower rate since the increase in minimum temperatures is counteracted by the decrease in maximum temperatures.[129]:89 There has been a decrease in the number of days with frost, and there have been increases in the frequency of hot nights and heat waves throughout the country.[14][130]:11

Within the next two or three decades (2016–2035), mean temperatures are predicted to increase by 0.5 to 1.0 °C (0.90 to 1.80 °F) under the two scenarios (RCP 4.5 and RCP 8.5) from the IPCC Fifth Assessment Report.[14] In both scenarios, the projected warming will be more pronounced during the summer months.[14] The predicted trend for precipitation is not as clear as the one for temperature.[129]:92 In the northern and central regions, precipitation is predicted to increase while in much of central–western Argentina and Patagonia, precipitation is predicted to decrease.[14] Because Argentina is potentially vulnerable to climate change, such projected changes based on the models could exacerbate current problems or create new problems associated with climate change in Argentina.[129]:25

It is predicted that glaciers will continue to recede and melt or, in some areas, disappear.[14] It is also predicted that the Cuyo region could face a potential water crisis due to an increase in water demand caused by a reduction in river streamflows.[14][129]:95 In northern Patagonia, a similar situation is projected in which there will be a negative impact on fruit and vegetable growing owing to a reduction in the river flow in the Colorado and Chubut rivers.[14][129]:97 In the north and central parts of the country, the higher temperatures and lower precipitation projected for this region will lead to higher evaporation, intensifying droughts and leading to desertification.[129]:94 Heat waves could become more frequent and intense, negatively impacting agricultural production while placing more demand on energy needs.[129]:94[132] Intense precipitation could become more common, increasing the likelihood of suffering from events such as flooding, since much of its population lives in urban areas near a body of water (rivers, lakes and oceans).[129]:33,95 Climate change could extend the habitats of vectors carrying tropical diseases such as malaria southwards.[133] Though most of the coastal regions of Argentina will not suffer permanent flooding associated with sea level rise, it is predicted that storm surges will become more frequent in coastal areas, affecting locations such as Buenos Aires.[14][15]:67[129]:98
