We obtained that there are two monsoon heavy rainfall belts in eastern China and the belts' numbers have two remarkable oscillation periods (30-60 days and 8-11 days), only the period of 8-11 days is remarkbale in a small region. There are two monsoon heavy rainfall periods in the middle and lower reaches of Changjiang river as in the Southern Chine, but the south of Changjiang river is an interrupted region of heavy rainfall. |
