| Abstract: |
| The development of micro-structure of precipitating convective cloud in heavy rainfall area at low-latitude is presented based on a numerical simulation of micro-physical processes with given vertical distributions of temperature and updraft. The effects of updraft in cloud,moisture supply at low level and ice concentration at upper level on the precipitation from convective cloud are also discussed. It is pointed out that the updraft in cloud and moisture supply at low level are important for the convective precipitation. |
