The year is still ongoing, and such, we need to keep the line of "tropical cyclones will form within seven different tropical cyclone basins". We also shouldn't include the Brazilian Navy Hydrographic Center as a notable warning centre, because they're not officially recognized by the WMO.

Throughout 2020, tropical cyclones will form within seven different tropical cyclone basins, which are located within various parts of the Atlantic, Pacific and Indian Oceans. During the year a total of 31 tropical cyclones have developed, with 19 of these being named by the appropriate warning centre. Tropical cyclones are primarily monitored by a group of ten warning centres, which have been designated as a Regional Specialized Meteorological Center (RSMC) or a Tropical Cyclone Warning Center (TCWC) by the World Meteorological Organisation. These are the United States National Hurricane Center (NHC) and Central Pacific Hurricane Center, the Japan Meteorological Agency (JMA), the Indian Meteorological Department (IMD), Météo-France, Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika, the Australian Bureau of Meteorology (BOM), Papua New Guinea's National Weather Service, the Fiji Meteorological Service (FMS) as well as New Zealand's MetService. Other notable warning centres include the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) and the United States Joint Typhoon Warning Center (JTWC).

Global conditions

As 2020 began, sea surface temperatures were above normal in the eastern Pacific Ocean near the equator, which had the potential to develop into El Niño conditions. On January 9, a group of climate scientists writing for ENSO Blog published their forecast for atmospheric conditions. They believed that there was a 60% chance that the environment would remain in neutral conditions related to the El Niño–Southern Oscillation (ENSO); this was based on the expectation that the above normal water temperatures would return to normal.[1] By March, there was little evidence of increased rainfall near the equator. Trade winds were enhanced in the central and tropical Pacific Ocean, and water temperatures remained above normal. On April 9, ENSO Blog reaffirmed their belief that environmental conditions would remain neutral.[2]

The COVID-19 pandemic disrupted the response to tropical cyclones during the year. In the South Pacific island nation of Vanuatu, COVID-19, travel and social distancing restrictions associated with the pandemic were lifted for those seeking safe houses and evacuation shelters.[3][4]

Systems

January

Cyclone Claudia

During January, no tropical cyclones developed within the Northern Hemisphere, while 10 systems existed within the Southern Hemisphere. Six of these systems were named and had gale force winds, while two of these named storms developed hurricane-force winds and were classified as Severe tropical cyclones. As the month opened, both Tropical Cyclones Calvinia and Sarai were weakening and gradually dissipated over the next few days. Tropical Cyclone Blake subsequently became the first named storm of the year and made two landfalls in the Kimberley Region, bringing heavy rainfall throughout the region. Adding on, Cyclone Tino brought considerable damage throughout the South Pacific in the middle portion of the month, and a rare South Atlantic tropical cyclone formed, named Subtropical Storm Kurumí, becoming the first of its kind to be named in January later on in the month.

February

Cyclone Ferdinand

The month of February saw 13 tropical cyclones develop, with eight being named. Cyclone Damien became the first storm of the month, impacting the Pilbara Region of Western Australia as a Category 2 cyclone on the Saffir-Simpson scale. Cyclone Uesi also impacted the east coast of Australia and New Caledonia, killing 1 person. Later in the month, activity increased in the South Pacific with Cyclones Vicky and Wasi forming, bringing heavy rain to the Samoan Islands. Consequently, activity also increased in the Australian basin with Cyclone Esther and Ferdinand forming, with Ferdinand peaking as a high-end Category 2 cyclone and becoming the strongest of the month.

March

Cyclone Herold

With only four tropical cyclones forming in March, the month was largely inactive. Despite that, Cyclones Gretel and Herold formed; with the latter becoming the first intense tropical cyclone of 2020.

  1. ^ The sum of the number of systems in each basin will not equal the number shown as the total. This is because when systems move between basins, it creates a discrepancy in the actual number of systems.
  2. ^ The sum of the number of fatalities in each basin will not equal the number shown as the total. This is because when systems move between basins, it creates a discrepancy in the actual number of fatalities.

Notes

2 Only systems that formed either on or after January 1, 2020 are counted in the seasonal totals.
3 Only systems that formed either before or on December 31, 2020 are counted in the seasonal totals.
4 The wind speeds for this tropical cyclone/basin are based on the IMD Scale which uses 3-minute sustained winds.
5 The wind speeds for this tropical cyclone/basin are based on the Saffir Simpson Scale which uses 1-minute sustained winds.
6The wind speeds for this tropical cyclone are based on Météo-France which uses wind gusts.
