Description
Summary:<!--!introduction!--> Extra-tropical cyclones transiting into the Arctic are of great importance for the heat and moisture budgets of the polar atmosphere and strongly modulate the sea ice variability. Arctic cyclones are also systems that lead to the formation of clouds, and in particular mixed-phase clouds, whose amount of supercooled liquid water strongly determine the radiative effect thereof. Correctly representing those clouds in atmospheric models is crucial to properly simulate precipitation s and the surface energy budget in a region warming twice as fast as the rest of the globe. In August 2022, the Rali-Thinice campaign took place in Svalbard and aimed to characterize the dynamical and microphysical structure of Arctic cyclones. A research aircraft equipped with measurement systems such as two radars, a lidar and microphysical probes flew over the Arctic Ocean sampling several cases of summer cyclones. The data acquired during this campaign are extremely valuable to carry out an in-depth ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
