| Abstract: | The variations of water storage at large space scales in Chinese mainland are inversed by use of 20 month GRACE gravity field solutions (from April 2002 to July 2004). Chinese mainland is divided into 8 major typical regions, the monthly variations of water storage in each region are calculated respectively, and then the results are compared with that derived from the NOAA’s CPC (Climate Prediction Center) hydrologic model. The comparison results show good consistencies in most regions: in Tibet, Southwest and South China, the amplitude of annual variations in water storage are about 12-14 cm, the maximum and minimum values appear in September and April respectively; and there are variations of about 8cm in East &; Central China and the eastern part of Southwest China,in Xinjiang area,the variation is obvious. However, in North &; Northeast China, there are obvious differences between the GRACE and CPC modeled results. |
