regions ( Xue et al. 1996 ). Although the variability of soil moisture is always considered a function of meteorological and hydrological parameters such as precipitation and temperature, its influences associated with changes in the heat content of soil and evaporation feedback are linked not only to variations in local precipitation and temperature but also to remote climate anomalies via changes in temperature and pressure gradients, and thus atmospheric circulation ( Pal and Eltahir 2002 ; Weaver

prediction studies, hydrometeorology, and the analysis of global energy and water cycle variability ( Sorooshian et al. 2005 ). Modeling activities are undertaken under the guidance of the GEWEX Modeling and Prediction Panel (GMPP), which develops and tests new parameterizations for land and cloud processes and model evaluation, as well as by the GEWEX Hydrometeorology Panel (GHP), which oversees GEWEX field campaigns and continental-scale studies. The GEWEX CSEs, coordinated by the GHP, have strongly

parameters, which are a function of soil, vegetation, topography, and other land surface properties. While the quality and availability of remotely sensed vegetation- and topography-related land surface parameters have improved significantly over the last few decades, comparable advances in global soil-related parameters at matching scales have not occurred. In fact, given that soil moisture is known to be a critical climate variable, it could be argued that our current approach of using texture

employed the global analyses prepared by the European Centre for Medium-Range Forecasts (ECMWF) to study the onset and interannual variability of the Asian summer monsoon in relation to land–sea thermal contrast ( Li and Yanai 1996 ), the Australian summer monsoon ( Hung and Yanai 2004 ), and its relationship with the Asian summer monsoons ( Hung et al. 2004 ). In China, in the last decade, a series of research programs have been organized to support the activities related to the World Climate Research
