摘　　要：为了做好郴州台风降水气候预测,对影响郴州台风降水的诸多气象因子做统计分析,结果表明,冬、夏季海温变化和西太平洋副热带高压位置是影响台风降水的重要因素,夏季暖水状态下,影响台风个数及降水总量偏少,但从冬季到夏季海温若处于上升趋势,且副高位置偏北时,影响台风个数及降水总量明显偏多;夏季冷水状态下,影响台风个数及降水总量偏多,但从冬季到夏季海温若处于下降趋势,且副高位置偏南时,影响台风个数及降水总量明显偏少。In order to improve the prediction of typhoon in Chenzhou,many meteorological factors affecting the typhoon precipitation in Chenzhou were analyzed. The results showed that the sea surface temperature（ SST） condition in winter and summer and the western Pacific subtropical high position are the important factors. When the SST is warm in summer,the frequencies of typhoon and precipitation in Chenzhou are less,but if the SST rise from winter to summer and the western Pacific subtropical high position are at north,the frequencies of typhoon and precipitation in Chenzhou are more. When the SST is cold in summer,the situation is converse.
