We present characteristics of global warm cloud properties and warm-rain process in conjunction with the aerosol index (AI)
and the lower-tropospheric stability (LTS). The Tropical Rainfall Measurement Mission (TRMM) Microwave Imager (TMI) and
Visible/Infrared Radiance Imager (VIRS) simultaneously derive cloud-top droplet effect radius, column droplet radius, cloud
fraction, cloud liquid water path, cloud optical depth, and a warm rain index. These cloud properties are clustered by
different bins of LTS, and then compared with GOCART-derived AI and MODIS-derived AI values. Results indicate that the
characteristics of the aerosol-cloud interactions significant vary between different cloud types and thermodynamic
environments. This indicates that the radiative effect and warm-rain process due to aerosols have significant heterogeneous
regional climate forcing effects.
