| Abstract: |
| In this paper we find that there are 7 more pluvial and 7 less pluvial periods to the east of 108 E and the south of 40 N of China in centurial scale since 1470, which begins from North China, then moves to Yangtze and Huaihe River Basin and finally to South China. With increasing(decreasing) temperature, more pluvial regions are to the South(North) in China. Phase difference of more pluvial regions may be associated with Hadley cell from North to South. Natural climatical change still plays an important part in the droughts of North China in the past decades and the floods in Yangtze River Basin in the past decade or more. |
