| Abstract: | Based on TRMM satellite data,the cloud physical characteristics of a local rainstorm in Hunan on June 23,2010 are investigated.The results show that(1) heavy precipitation system consists of one major rain cloud cluster and some scattered clouds,among which convective cloud with less area,contributed more to the total rainfall than the stratus cloud systems with more area;(2) the areas with abundant precipitable ice/water were consistent with the strong upward motion areas;(3)the intensity of precipitable ice/water can provide useful microwave scattering information for rainfall analysis,while cloud water/ice doesn’t show good signature for precipitation;(4) the positive feedback mechanism between the convective motion and the latent heat released by precipitable ice-water phase transition,promotes the maintenance and development of heavy rain. |
