GRACE反演近年青藏高原及雅鲁藏布江流域陆地水储量变化
Inversion of terrestrial water storage changes in recent years for Qinghai-Tibetan plateau and Yarlung Zangbo River basin by GRACE
摘要
Abstract
With the GRACE (Gravity Recovery and Climate Experiment) data from 2005 to 2010, terrestrial water storage changes of Qinghai - Tibetan Plateau and Yarlung Zangbo River Basin were inversed and systematically analyzed. The preliminary results indicated a persistent decreasing trend in the yearly terrestrial water storage level with significant seasonal fluctuation in the study region. Comparisons of GRACE based inversions with those simulated by internationally well - known hydrological models suggested the significant discrepancies existed either for yearly or for seasonally terrestrial water storage changes. In general, CPC model simulated quite similar variation treads compared to GRACE reversed but with a smaller fluctuation magnitude. However, both CLM and VIC models released by GLDAS give quite different outputs compared with that reversed by GRACE. The discrepancy is mainly attributed to the shortcomings in ground water variation simulations for the most of hydrological models. Moreover, the complex meteorological, hydrological and the underneath conditions in Qinghai - Tibetan Plateau usually result in errors for hydrological simulations.关键词
