Abstract

On the basis of meteorological sounding data at 15 stations in the Three Gorges Reservoir Area (TGRA) and its surroundings from 1980 to 2009, the variation characteristics of water resources in air over the TGRA are analyzed. The results show that the water vapor content increases gradually from northeast to southwest over the TGRA. The water vapor over the TGRA mainly comes from the transportation of southwest water vapor, which has the greatest intensity in summer. There is convergence of water vapor over most of the TGRA, apparently in northwest and southeast of the TGRA. The water vapor over the TGRA mainly inflows from south boundary and outflows from east boundary. The net water vapor flux is positive in each month, showing a single peak changes at maximum in July. The integrated net water vapor transport flux has experienced a parabolic decadal change with first increasing and then decreasing, and had an decreasing trend in spring and winter and an increasing trend in summer, autumn and annual mean in the past 30 years.

Key words： Three Gorges Reservoir Area; water resource; water vapor transport
