摘要
采用气候极端降水分析方法,把降水时空分布特征结合起来进行研究,揭示了近40年中国和日本不同量级降水特征及变化趋势。同时分析了阶段性气候极端降水在降水长期变化中的差异,并分析比较了我国华北降水不同变化阶段日雨量的变化特征,指出两者的主要差别在极端降水的量值上。
In accordance with the last 30 ̄40 years precipitation over China and Japan, a new analysis method has been constructed for the spatial and temporal integrated characterics of the climate extreme precipitation. Results show that there are different features and variability trend for different variety precipitation. Extreme light and moderate rain days, maximal extreme daily rainfall and etc. decrease slowly in China, and on the contrary, mean precipitation density and maximal monthly rainfall increase slightly, same as the trend of extreme annual heavy rain in Japan. Evidence suggest that these characterics are dependent on the large scale precipitation background.
