Climate Summary for February-April 2020

This is the main result from the climate summary stated in the ACF-5 Consensus statement, for temperature, precipitation and sea ice during February, March and April 2020. View the full climate summary presentation for more details. The strong positive surface air temperatue anomaly (warmer than normal) over Eurasia and the Arctic Ocean contributed to below to near normal ice conditions observed in winter 2020 across the entire Arctic region.

 

Temperature FMA 2020 Summary

The figure below shows February, March, and April (FMA) 2020 surface air temperature anomaly based on the 1981-2010 reference period. Red indicates warmer than normal temperatures, and blue indicates cooler than normal temperatures. The map is produced by the Hydrometcenter of Russia https://meteoinfo.ru/ with ERA-5 as data source. The FMA 2020 average surface air temperatures in the Arctic north of 65°N ranged from higher than normal in the eastern hemisphere, to lower than normal in the western hemisphere. Scandinavia and the majority of the Eastern and Western Scandinavia regions experienced warmer than normal conditions (red areas), while the majority of Canada, Alaska, Greenland, and the North Atlantic Ocean experienced near normal (white areas) or slightly below normal (light blue areas) conditions. Using data from NCEP/NCAR reanalysis to rank the average surface air temperature, the boundary between Eastern and Western Siberia saw their fifth warmest FMA period, on average, since the start of the record in 1949 (not shown).

Precipitation FMA 2020 Summary

The figure below shows FMA 2020 precipitation based on the 1981-2010 reference period. Red indicates wetter than normal conditions, and blue indicates drier than normal conditions. Map produced by the Hydrometcenter of Russia https://meteoinfo.ru/ with ERA-5 as data source. Wetter than average conditions were observed during FMA 2020 across the majority of Arctic region (red areas). Only a few isolated areas, including the northeastern coast of Greenland, northern Canada, and a small swath over southern Alaska, experienced drier than average conditions (blue areas).

Sea Ice Summary for March 2020

The figure below shows the blended Arctic ice chart (AARI, CIS, NIC) for 16-19 March 2020 and ice edge occurences for 16-20 March for 1999-2018, with total concentration to the left, and predominant stage of development to the right. Maximum sea-ice extent, volume and thickness is normally reached each year in the Arctic during the month of March. The 5.81 mln km2 maximum sea-ice extent reached on March 5, 2020 is the 11th lowest maximum sea-ice extent since 1979, but the highest since 2013.
