黄河流域旱涝物理成因模拟与分析

ANALYSES AND SIMULATIONS FOR THE PHYSICAL REASONS OF DROUGHT AND FLOOD IN THE YELLOW RIVER VALLEY

本文分析了近500年黄河流域旱涝的演变特征,并且利用几个较著名的全球三维环流模式的模拟结果分析了各种物理因子对华北地区旱涝影响的大小,同时利用观测资料亦分析了这些物理因子与黄河流域旱涝的相关。

The evolution of drought and flood in the Yellow River Valley for the last 500 years hasbeen analysed.Sensitivity experiments as simulated by several famous GCMs to examine the in-fluences of the physical factors on the climatic change in north China have been summarized.Statistic correlation analysis between the drought and flood in the Yellow River Valley and somephysical factors for the observed data have been calculated.
