Study of Midlatitude and Arctic Aerosol-cloud-radiation Feedbacks Based on LES Model with Explicit Ice and Liquid Phase Microphysics
Abstract
LONG TERM GOALS. The development and improvement of cloud microphysical and radiative parameterizations for use in mesoscale models OBJECTIVES. Investigation of marine stratocumulus clouds microphysics and radiative processes using the CIMMS LES model with explicit microphysics and radiation. The data from FIRE II/ASTEX and MAST field experiments will be used to validate the model and to improve our understanding of the interactions between the microphysical, radiative, and thermodynamical processes. APPROACH. The modeling part of the research is based on the CIMMS 3-D LES model of boundary layer stratocumulus clouds with explicit formulation of aerosol and cloud drop size-resolving microphysics. The model has been thoroughly tested against observations from ASTEX and MAST field programs. It is then used to generate 3D data fields, including the rates of various microphysical processes needed to find relations between bulk variables that can be forecasted in numerical weather prediction models.
