Abstract

An effect of the implementation of the new aerosol-cloud-radiation interaction scheme in the COSMO model is described. The results of simulations with the new scheme are given for various values of the aerosol concentration. The aerosol effect on the forecast of cloud microphysical characteristics and radiative fluxes was determined. The study conducted for Meteorological Observatory of Moscow State University for a warm period (April – October) 2018. Values of integral cloud water/ice content obtained in experiments with fixed cloud nuclei concentration were noticeably smaller than in experiment with aerosol climatological data. Simulations shown the decreasing of global radiation with increasing cloud particle number that is connected with increasing of the concentration of cloud nuclei. We obtain better results against observations when cloud nuclei concentration is set according to Tegen aerosol climatology compare to fixed concentration.
