Many studies have been done on the variation of large scale mean temperature. However, it is difficult to build a long-term time series of global or hemispheric mean precipitation. In this note, we attempt to make the time series of the mean annual rainfall over east China in the recent hundred years to have a view of historical fluctuation of large scale drought and flood in quantities.展开更多
