Altitudinal zonation

From Wikipedia, the free encyclopedia

Jump to: navigation, search

Altitudinal zonation or Altitudinal variation is the creation of zones to explain the different characteristic climates at different elevations. The different zones can support different vegetation, agriculture, etc. As one moves to higher elevation points one enters different altitudinal zones. Founded by a geographer named Alexander von Humboldt. Humboldt is also credited with Environmental Lapse Rate - the measure of how many degrees temperature drops as you move to higher elevation. By his delineation (in 1817) of "isothermal lines", he at once suggested the idea and devised the means of comparing the climatic conditions of various countries.

[edit] Introduction

  • Temperature: 1,000 m higher, the air temperature is around 5 °C colder, or around 3 °F (1.67 °C) every 1,000 ft (304.8 m).

Saturated adiabatic lapse rate is usually near +4.9 °C/1,000 m (+2.7 °F/1,000 ft or +1.51°C/1,000 ft) at temperatures above freezing. [1]

  • Humidity: every 5 °C warmer, the water vapor content of saturate air increases around 30%. The Peruvian tales are drier than the Amazonic plains. Examples:
    • Manaus, Brazil; 72 m; annual mean temperature 26.6 °C; annual mean precipitation 2,897 mm.
    • Leticia, Colombia; 84 m; annual mean temperature 25.8 °C; annual mean precipitation 3,298 mm.
    • Yurimaguas, Peru; 184 m; annual mean temperature 26.9 °C; annual mean precipitation 2,047 mm. [2]
    • Cuzco, Peru; 3,249 m; annual mean temperature 12.5 °C; annual mean precipitation 736 mm.
  • Biogeography (WWF):
    • Ecoregions borders are most of the times a compromise of the distribution of many species.
    • Ecoregions have most of the times an intrinsic inhomogeneity.
    • Borders of ecoregions are most of the times a transition, they are an ecotone. [3]

  • Sea level, estimated 22 - 24 °C (75 °F, but the cold Humboldt Current generates fog);
  • Tierra Caliente (Hot land) up to 750 (about 2,500 ft) - 1,000 m;
  • Tierra Templada (Temperate land) up to 1,850 (about 6,000 ft) – 2,000 m

(the warmest month has an average temperature of below 22 °C or 72 °F);

  • Tierra Fria (Cool land) below 3,600 m (about 12,000 ft, Tree line)

(the warmest month has an average temperature of below 18 °C or 64 °F);

(the definition of Tree line of Coniferae: the warmest month has an average temperature of below 10 °C or 50 °F );

(just warmer than -1 °C over rocks or just warmer than -3 °C over snow).

In the altitudes between 3,400 meters (11,000 feet) and 4,500 meters (15,000 feet) some of the most extreme examples of adaptations can be found. At altitudes below 3,400 meters (12,000 feet) the daily temperature fluctuations are less extreme, the average daily temperature steadily increases, and the growth forms and ecology of the Dendroseneico reflect the increased influence of biotic factors (such as competition for light) over abiotic factors (such as nightly frost). [26]

[edit] Jade Dragon Snow Mountain, 13 peaks

It is the glacier nearest of the Equator on the North Hemisphere. The landmarks 4,506 m and 4,680 m at the end of the glacier can be achieved through the cable car from Ganhaizi (tibetan for dry lake, a grassland with conifers at 3,400 m). The mountain desert begins around 4,000 m. The Three Parallel Rivers of Yunnan (Unesco World Heritage Site) encompasses the watershed areas of the Yangtse (Jinsha), Mekong (Lan Cang) and Salween (Nujiang) rivers and is the joint of the Palearctic ecozone and the Indomalaya ecozone.
