摘要
综述了我国７月份雨型的划分方法，各种雨型的多雨特点及环流特征，总结了各类雨型的预报判据。着眼于赤道东太平洋海温（ＳＳＴ）、冬季（１—３月）５００ｈＰａ环流、春季（３—５月）西太平洋副热带高压、夏季（６—８月）赤道平流层纬向风准两年振荡（ＱＢＯ）等方面，分析了与７月雨型的关联。
The dividing method of the rainfall pattern in July,the circulation features and the forecast ing criteria of each rainfallpattern are summarized.The relationship is analysed between the three rainfall patterns and the factors of SST in eastern equatorial Pacific,the circulation at500hPa lev el in Winter,the subtropical high in western Pacific in Spring,as well as the QBO windphase in Summer.This method is of some guide to the forecast of China precipitation inJuly.
