Description :
The characteristics of water vapor transport (WVT) over China and its relationship with precipitation anomalies in the Yangtze River Basin (YRB) are analyzed by using the upper-air station data in China and ECMWF reanalysis data (developed by European Center for Medium-Range Weather Forecasts) in summer from 1981 to 2002. The results indicate that the first mode of the vertically integrated WVT is significant whose spatial distribution presents water vapor convergence or divergence in the YRB. Finally the AA. analyze how the atmospheric circulation causes the WVT anomaly.
