| 摘 要： | 在相关普查及分析各因子物理意义的基础上，建立了宁夏夏季降水的概念模型和预测模型，结果表明：夏季500hPa高度场上欧亚中高纬地区为乌山脊、巴尔喀什湖至贝加尔湖地区为槽，赤道东太平洋海温低，印度低压弱，以及西太平洋副热带高压脊线位置偏北时，宁夏夏季易多雨，反之易少雨。

| Abstract: | Based on the physical meaning of each factor and theirs correlation,the conception forecast model of summer precipitation in Ningxia is set up. The result indicated that,as the high-pressure ridge aloft occurred on 500hPa above Ural Mountains area, at the low pressure trough aloft above from Balkhash to Baikal lake the sea surface temperature was low on the equator in the East Pacific,Indian low-pressure is weakened, and the ridgeline of the West Pacific sub-tropics high pressure moved towards the north, it is likely to be rainy during summer days in Ningxia, contrarily likely to be rainless. |
