Combined measurements of the water cycle parameters during the MOSAiC expedition allow evaluation of the moisture conversion processes in the Central Arctic atmosphere. These parameters include integrated amounts of supercooled cloud liquid and ice, snowfall rate near the ground and precipitable water vapor. This poster will present observationally-based statistical relations among these components of the water cycle during periods of the solid precipitation during the MOSAiC icebreaker drift from October 2019 through May 2020. The observationally-based relation could be used evaluating snowfall parameterizations in weather and climate models. Additionally, this poster will present results of applying Ka-W band dual-wavelength radar measurements from the ARM KAZR and MWACR vertically pointing radars for retrievals of characteristic size of snow particle. The retrieval results illustrate the growth of these particles via aggregation and riming process at different heights in the atmosphere. Finally, this poster will evaluate influences of the MOSAiC icebreaker angular movements on measurements of ARM radar Doppler moments.
