摘要
利用全国743个站点1971―2000年的降水资料、国家气候中心发布的西太平洋副热带高压各指数资料以及SLP和NCEP/NVAR资料归一化东亚夏季风资料对全国6—8月的降水与西太平洋副热带高压以及东亚夏季风进行了分析。结果表明:西太平洋副热带高压偏北,东亚夏季风较强,华北地区降水偏多;反之,西太平洋副热带高压偏南时,东亚夏季风较弱,华北地区降水偏少。
Based on the rainfall data from 743 sites precipitation data of 1971-2000 in China, the index of Western Pacif ic subtropical high from national climate center and SLP, NCEP/NVAR data , the Western Pacif ic subtropical high and the East Asian Summer Monsoon(EASM) were normalized. The results showed that the Western Pacif ic subtropical high has an obvious trend of moving north, the east Asian summer monsoon is stronger and more rainfall in north China;On the contrary, the Western Pacif ic subtropical high has an obvious trend of moving south , the east Asian summer monsoon are weaker and less rainfall in north China.
