祁连山东段西营河流域气温与降水要素特征分析

Based on the temperature and precipitation data of the three automatic weather stations (Shachi weather station, Ningchan weather station, Xiying weather station) and eleven general weather stations in the Xiying valley of the east Qilian Mountain from September 2006 to August 2008, we had analyzed the variations of daily mean air temperatures and diurnal variations of the air temperatures (four seasons) of the three automatic weather stations，as well as the air temperature variation and summer precipitation variation as the variation of the altitude in the Xiying valley, at last established the Multiple Regression Equations of the precipitation and the precipitation distribution model, to research the precipitation distribution in the small valley.
