| Abstract: | The advances obtained by the project "Investigation on Laws, Causes and Predictions of Droughts And Floods In The Yellow River valley And The Yangtze River valley of China" for this three years are reviewed in this paper. The laws of decadal scale, interannual and Intraseasonal variations and circulation conditions of droughts and floods in these two valleys are analysed in detail. Moreover, the preliminary views of the causes of droughts and floods in these two valleys are put forward. The investigations of the project have pointed out that the thermal state in the western Pacific warm pool and the connective activities over the warm pool and the connective activities over the Tibetan Plateau may be siganificant causes of droughts and floods caused in these two valleys. Besides, the numerical simulation of occurance and circulation condition of droughts and floods resulted in these two valleys and their prediction experiments have been made by using the atmospheric general circulation model.
In this paper, the problems in research of the project are also analysed so that to obtain the investigated results in more higher level. |
