摘  要:
对8908、9309、0307、0606、1003号5个台风登陆后的环境场和物理量场进行对比分析,试图找出其登陆后降水差异的原因,得出热带气旋临近登陆和登陆后的24 h强降水预报方法。结果表明,影响广西的热带气旋暴雨范围和强度与副热带高压脊线的位置、副高西侧588 dagpm线位置的变化及其是否存在高压坝密切相关。台风影响过程中,当95°~113°E、25°~35°N区域500 hPa有高空槽活动,强降水区范围较大并向北发展,降水强度也较强。台风环流影响广西过程中,其东侧500~850 hPa南风分量中心值越大,出现大暴雨或特大暴雨概率越大,范围越大,强降水范围也越大,而当500~850 hPa南风分量向北推进到广西中北部,强降水区也向北扩展;台风影响广西时,强降水区所处位置与高层200 hPa散度场及低层850 hPa涡度场对应较好。强降水过程中广西及华南地区上空的空气非常潮湿,而相对较弱降水过程中广西及华南地区上空的空气比较干燥。

摘  要:
The environment field,physical quantity field of Typhoon 8908,9309,0307,0606 and 1003 after landing were comparatively analyzed.The causes for precipitation difference after land were found,the strong rainfall precipitation method was obtained.As indicated by the results,the factors for influencing rainstorm range and intensity in Guangxi include subtropical ridge line location,location variation of west side of subtropical high 588 dagpm line and whether have high pressure barrier.The heavy rainfall range became larger and moved to north when there are high-level trough activities at 95°-113°E,25°-35°N.The probability of heavy rainstorm was larger with increase of south component center value at east side 500-850 hPa.
