A Study of Downscaling Factors of Atmospheric Circulations in the Prediction Model of Summer Precipitation in Eastern China
大气环流降尺度因子在中国东部夏季降水预测中的作用

The factors of atmospheric circulations in the prediction model, which is built by the downscaling techniques and the partial least square regression for summer precipitation in eastern China, are studied by using the monthly data of the 74 characteristic quantities of the northern hemispheric circulations, and the precipitation at 160 stations over eastern China. The study is based on the occurrence frequency of the characteristic quantity in the best prediction model. The results show that the factors wit...
