摘　　要：利用降水和多普勒天气雷达资料,分析了2006年7月14日夜间强热带风暴碧利斯登陆期间,发生于罗霄山区资兴市的一次特大暴雨的过程,并通过与传统无线电探空资料比较,发现大气红外探测仪AIRS数据产品在山区强对流活动成因分析中的应用价值。研究发现,当强热带风暴碧利斯中心位于资兴市以东约400 km之时,引发了研究区东江水库盆地内的一次对流风暴,并形成了所谓列车效应,造成局地特大暴雨。发现依靠传统无线电探空资料难以有效预报这一对流风暴,而采用AIRS产品数据发现,台风暴雨发生前约8 h时东江水库盆地低层大气即存在局地强逆温层,有利于不稳定能量的积累。研究区逆温层受到碧利斯外围气流影响而释放不稳定能量,很可能是导致此次特大暴雨的重要原因。Using precipitation and Doppler weather radar data,we analyze the process of a heavy rainstorm occurred in Zixing City,Luoxiaoshan Mountains during the landfall of strong tropical storm Bilis on July 14,2006.By comparing with traditional radio sounding data,we find the application value of AIRS data products of atmospheric infrared detector in the cause analysis of severe convective activity in mountainous areas.It is found that when the center of strong tropical storm Bilis is located about 400 km east of Zixing City,it triggered a convective storm in the Dongjiang Reservoir Basin of the study area,and formed the so-called train effect,resulting in local heavy rainstorm.However,the analysis of AIRS data indicated a strong inversion layer over the Dongjiang Reservoir basin about 8 hours before the occurrence of the convective storm.This research shows the instability of atmosphere which was released by Typhoon Bilis was an important cause of the intense convective storm.
