According to the negative correlation between rainfall in the first flood period in South China (FFSC) and sea surface temperature anomalies (SSTA) in a key region in western Pacific warm pool (West Region), two sensitive experiments are designed to investigate the effects of the latter on the former and the possible physical mechanism is discussed. It is found that in cold water (warm water) years, the rainfall in South China (SC) is far more (less) than normal, while the rainfall in the middle and low reaches of the Yangtze River is relatively less (more). The best correlative area of precipitation is located in Guangdong Province. It matches the diagnostic result well. The effect of SSTA on precipitation of FFSC is realized through the abnormality of atmospheric circulation and tested by a P-σnine-layer regional climate model. Moreover, the simulated result of the P-σmodel is basically coincident with that of the CCM3.展开更多

China increasingly realizes the importance and urgency of the water resource governance in the regional cooperation, but under complicated geopolitical context, China's water resource governance must serve several important main functions in its regional cooperation. Overall, water resource governance is the demands of crisis management and conflict prevention, and also is a kind of positive factor that promotes sub-regional cooperation. From the perspective of the current situation, China should take more proactive attitude toward the water resource governance, expand the areas and stakeholders of the water resource governance, and thus promote the formulation of water resource governance strategy.展开更多
