The HALO-(AC)3 aircraft campaign was carried out in March and April 2022 over the Norwegian and Greenland seas, the Fram Strait, and the central Arctic Ocean. Three research aircraft - the High Altitude and Long Range Research Aircraft (HALO), Polar 5, and Polar 6 - pe ...
This case study explores the evolution of clouds during an Arctic cold air outbreak in the Fram Strait region observed during the HALO-(𝒜𝒞)3 aircraft campaign. Our research provides information about the formation, structure, micro- and macrophysical properties, radiative effects ...
Cold and dry Arctic air masses moving from sea ice southward over the open ocean rapidly heat up, moisten, and form clouds. Diabatic heating and moistening rates in such marine cold air outbreaks (CAOs) are key to understanding their dynamics. While state-of-the-art atmospheric r ...

Thermodynamic and cloud evolution in a cold-Air outbreak during HALO-(AC) 3

Quasi-Lagrangian observations compared to the ERA5 and CARRA reanalyses

Arctic air masses undergo intense transformations when moving southward from closed sea ice to warmer open waters in marine cold-Air outbreaks (CAOs). Due to the lack of measurements of diabatic heating and moisture uptake rates along CAO flows, studies often depend on atmospheri ...
Marine cold-air outbreaks (MCAOs) strongly affect the Arctic water cycle and, thus, climate through large-scale air mass transformations. The description of air mass transformations is still challenging, partly because previous observations do not resolve fine scales, particularl ...
