Temperature-Moisture Impact on Arctic Cloud Formation
Warm and moist air intrusions from lower latitudes into the Arctic results in the formation of clouds, being the main energy source of the Arctic, except in summer. The infux of moisture leads to the development of clouds with higher liquid and ice water content, contributes to Arctic amplification, and influences the Earth's radiative budget and water cycle. In order to clarify the contributions to the development and dissipation of mixed-phase clouds from heat and moisture intrusions, and parameterize the cloud radiative effects in the global climate models, large-eddy simulations are performed by the UCLALES-SALSA model that explicitly resolves interactions between aerosols, water droplets, and ice droplets with a bin microphysics scheme, and the simulations are initialized using observational data from the Physical Feedbacks of Arctic Boundary Layer, Sea Ice, Cloud and Aerosol campaign in summer 2017.
