Impact of Coarse-Mode Aerosol on Jiangxi Warm Clouds: An SBM-FAST Approach

A double-nested approach was adopted, with grid resolutions of 3km and 1km, respectively, and the innermost grid size being 376×376. The microphysics scheme selected was the SBM-fast bin scheme (FSBM-2) under WRF version 4.2; the boundary layer scheme used was the Mellor-Yamada-Janjic (Eta) Turbulence Kinetic Energy (TKE) scheme, the surface layer scheme adopted the Monin-Obukhov (Janjic Eta) scheme, the land surface model used was the unified Noah land-surface model.

The shortwave and longwave radiation schemes were the (old) Goddard shortwave radiation scheme and the Rapid Radiative Transfer Model (RRTM) scheme, respectively.2.The simulation utilized the fifth generation of the European Centre for Medium-Range Weather Forecasts (ECMWF) global atmospheric reanalysis (ERA5) hourly pressure level data as the initial field, with a resolution of 0.25°×0.25°.These data can be accessed at the following link: cds.climate.copernicus.eu/cdsapp#!/dataset/reanalysis-era5-pressure-levels?tab=overview.
