针对现在的降雨资料严重不足问题,基于对我国南方湿润地区的沅江流域与半干旱地区的岔巴沟流域的实测资料分析.以及前人的研究成果,本文尝试提出了一种由日降雨资料时间降尺度生成小时降雨资料的方法。该方法的优点是计算简单,能保证模拟的日降雨的总量同实际的完全一致,模拟的雨强同实际的基本一致。是解决缺资料或无资料地区降雨资料不足问题的一种简单适用的方法。
method in Yuanjiang According to scarcity of the observed precipitation, this paper proposed a precipitation temporal scale Basin is in the downscaling based on the statistical analysis of the fiver basins of Yuanjiang and Chabagou. The humid zone of the South China, and the Chabagou Basin is in the semi-arid zone of the Northwest China. The proposed method can insure that there is not only an consistency between observed and simulated precipitation data, but also between the rainfall intensities. The application results indicate that this method is simple and practical.
