Research Abstract

In addition to the relation between the precipitation amount and low-cloud properties and contribution of meteorological factors on the surface shortwave irradiance variation obtained from conventional passive satellite sensors, recent data from active satellite sensors revealed the behaviors, similarities and differences in the transition among cloud droplets, drizzle and precipitation particles over China and the Amazon from the analyses of cloud vertical profiles and the radar reflectivity. Moreover, the numerical modeling illustrated that the difference in statistical behaviors between the optical depth and effective particle size was caused mainly by the difference in shapes of aerosol size spectra.
