| 摘 要： | 选取黄河上中游流域43站1961-2006年夏季降水量作为研究对象,应用线性相关分析、EOF分析等方法,分析了流域内夏季降水与北半球100hPa、500hPa、海平面气压、海表温度、地面射出长波辐射(OLR)、青藏高原和西北干旱区地面气温以及74项环流特征量等资料前期至同期的关系,建立了该区域夏季降水气候预测的概念模型。

| Abstract: | Using the ground monthly precipitation data from 43 stations along Yellow River valley and the monthly mean girded 100hPa,500 hPa,SLP,SST,OLR data,NCEP reanalysis method,temperature data of the Tibet Plateau and 74 circulation characteristic quantities by CMA,the relationship between the precipitation and their dates in Northern Hemisphere was analyzed by EOF,correlation analysis etc.the climate forecast conceptual model on precipitation of the region in summer was established. |
