摘要：
Climate change is expected to strongly alter future global hydrological cycle according to recent IPCC AR5 projection. The anticipated consequences to the terrestrial water cycle and severe impacts to the society are more frequent occurrence of floods and droughts in the future. Among the global water cycle components, terrestrial water storage (TWS) is the key state variable, and also the one most difficult to estimate. Despite its importance in affecting global circulation of both atmosphere and ocean and in shaping weather and climate of the Earth, there are currently no extensive in-situ networks existent for monitoring large-scale TWS variation. In this presentation, TWS variations are estimated over selected global largest river basins by using both the hydrologic model simulations and atmospheric-land water balance analysis. The obtained TWS estimates are then compared with available in-situ observations and satellite measurements from the Gravity Recovery and Climate Experiment (GRACE) mission. The ultimate goal is to provide a quantitative assessment on the dynamics controlling the propagation of hydrologic and climatic anomalies (i.e., propagation of floods and droughts) across the atmospheric and terrestrial water cycle in the regional to global scale.
