After the sea-ice extent in the Arctic showed a moderate loss, hovering in the lower portion of the double standard deviation range from the long-term average with ca. 92,000 km² / day in the first ha
Ever since, atmospheric researchers Dr Dörthe Handorf and Dr Annette Rinke at the AWI in Potsdam have been searching for concrete evidence of the interrelations between the sea ice, polar air currents
The MOSAiC ATMO (Atmosphere)-Team (Figure 1) made observations of relevant atmospheric properties, processes and interactions over an entire annual cycle while drifting across the Central Arctic with
Despite a storm and the adverse ice conditions, he and his team reached the MOSAiC floe almost as planned. They left the floe on 16 May and reached the sea-ice edge on Tuesday, 2 June. Now Torsten Kan
The stratosphere is the part of our atmosphere beginning at an altitude of ca. 10 km, and where, thanks to the absorption of the trace gas ozone, temperatures rise with increasing altitude. Normally,
During the MOSAiC expedition, researchers from 19 countries will study the Arctic throughout an entire year, spending the winter in a region that is virtually inaccessible in the polar night. Alone th
But this year, February was extraordinarily warm. Analyses of satellite and station data indicate that very warm air has been advected towards the Arctic, which allowed temperatures to rise until the
In the span of these two months, sixteen Arctic weather stations operated by seven different countries sent up more than 1,900 additional weather balloons. In an effort to close the remaining gaps in
The air temperature, humidity, pressure and wind fields determine the circulation, and with it, the inflow of warm air masses from the temperate latitudes. In addition, the ocean temperature is the mo
