摘要
The sustained rainfall process on May 13-22, 2004 was one of the pre-summcr rainy periods in the south of China. It was related with the genesis and development ofa SW monsoon surge over the Bay of Bengal. From the synoptic analysis it is found that the genesis and development of the SW monsoon surge may be dividod approximately into the initial, developing and decaying stages. During the rainfall the Southern Hemisphere cross-equatorial flow over the Indian Ocean plays a triggering role.
