| 摘 要： | 通过对高原季风指数与西北地区月降水量遥相关关系的分析，论述了１月份高原冬季批指数与西北地区年降水和夏季月降水相关显著，其相关分布型与西北夏季三种降水类型相似；６月高原季风指数对西北降水量的影响也最明显。高原季风异常可能与高原下垫热力异常有关，从而推测冬季风异常通过高原这个巨大的热载体而影响夏季风异常。

| Abstract: | Analysinsing the correlation between Qinghai-Xizang plateau monsoon and precipitation in the NW China shows that it is significant between plateau winter index in January and annual precipitation and monthly precipitation in NW China,the correlation curve pattern is similar with three kinds of precipitation,and the relation of plateau summer index in June and monthly precipitation is obviously.It is suggested that the monsoon abnormity in plateau is affected by the special surface thermotics which is the media of winter monsoon abnormity leading to summer monsoon abnormity. |
