Abstract:
An overview of the weather conditions associated with the very-short-range torrential rains in Guangzhou is presented,with emphasis on the evolution of environmental and several storm-cell's Doppler characteristics relevant to the forecasting of heavy rains,using data from a new generation Doppler weather radar(CINRAD-SA) in Guangzhou and conventional weather observation networks.The formation mechanisms of the torrential rains are investigated.It is found that this severe rainstorm case occurred in the favorable synoptic conditions with the multi-cell echo band orientated from northeast to southwest,being consistent with its moving direction.The weak mesocyclone features are found in the strongest cell with the longest life time.The "inverse-wind region" played an important role in the development and maintenance of convection.
