摘要2006年7月14日登陆中国大陆东南沿海的北太平洋强热带风暴碧利斯，其残留环流持续到2006年7月17日以后，本文通过观测研究，试图确定碧利斯引起的中国南方大面积降水分布的影响因素。碧利斯登陆期间和登陆后的大暴雨可分为三个阶段。第一阶段的暴雨主要发生在福建和浙江两省，暴雨登陆时的内核环流直接诱发了第一阶段的暴雨。第三阶段的降雨发生在沿着广东和福建沿海地区，可能是由于碧利斯和南海季风的相互作用，沿海沿着地形抬升增强。第二阶段的降雨出现在江西、湖南、广东三省交界的内陆地区，造成了严重的洪涝灾害。
Abstract This observational study attempts to determine factors responsible for the distribution of precipitation over large areas of southern China induced by Bilis, a western North Pacific Ocean severe tropical storm that made landfall on the southeastern coast of mainland China on 14 July 2006 with a remnant circulation that persisted over land until after 17 July 2006. The heavy rainfalls associated with Bilis during and after its landfall can be divided into three stages. The first stage of the rainfall, which occurred in Fujian and Zhejiang Provinces, could be directly induced by the inner-core storm circulation during its landfall. The third stage of rainfall, which occurred along the coastal areas of Guangdong and Fujian Provinces, likely resulted from the interaction between Bilis and the South China Sea monsoon enhanced by topographical lifting along the coast. The second stage of the rainfall, which appeared inland around the border regions between Jiangxi, Hunan, and Guangdong Provinces, cause...
