Studies on the Relationship between the Severe Climatic Disasters in China and the East Asia Climate System

Huang Ronghui, Chen Jilong, Zhou Liantong, and Zhang Qingyun (Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100080)  
In the base of summarizing the studies on the kinds, the characteristics of spatio-temperai distribution and the formtion mechanism of the severe climatic disasters such as droughts and floods etc. in China, the impacts of the East Asian climate system on the water cycle in East Asia and the severe climatic disasters such as droughts and floods etc. occurred in China are analyzed in this study. Especially, the formation mechanism of severe climatic disasters in China are analyzed and discussed from the effects of various components of the East Asia climate system including the East Asian monsoon, the western Pacific subtropical high, and the disturbances in mid-latitudes in the atmosphere, the ENSO cycle, the thermal states of the West Pacific warm pool and the Indian Ocean in the Ocean, and the dynamical and thermal effects of the Tibetan Plateau and the snow cover in the Tibetan Plateau on the occurrence of climatic disasters in China. Moreover, the influencing processes of the East Asian climate system anomaly on water cycle in East Asia and severe climatic disasters in China are analyzed further combining with the actual facts of particularly severe flood occurred in the Yangtze River valley in the summer of 1998 and the prolonged droughts occurred in North China from the late 1970s.
