Previous estimates of land-atmosphere interaction (the impact of soil moisture on precipitation) have been limited by a lack of observational data and by the model dependence of computational estimates. To counter the second limitation, a dozen climate-modeling groups have recently performed the same highly controlled numerical experiment as part of a(More)
The Global Land–Atmosphere Coupling Experiment (GLACE) is a model intercomparison study fo-cusing on a typically neglected yet critical element of numerical weather and climate modeling: land– atmosphere coupling strength, or the degree to which anomalies in land surface state (e.g., soil moisture) can affect rainfall generation and other atmospheric(More)
The anticipated water scarcity in the first half of this century is one of the international issues of most concern, which needs to be adequately addressed. However, even though the issue has an international impact and worldwide monitoring is critical, there are limited global estimates at present. In this study, annual water availability has been derived(More)

The 12 weather and climate models participating in the Global Land–Atmosphere Coupling Experiment (GLACE) show both a wide variation in the strength of land–atmosphere coupling and some intriguing commonalities. In this paper, the causes of variations in coupling strength—both the geographic variations within a given model and the model-to-model(More)
As part of GAME-Tropics, the controversial issue of deforestation effects on regional climate is addressed. Many numerical deforestation experiments have been carried out (e.g., Dickinson and Henderson-Sellers, 1988), with results showing that rainfall decreases as a result of deforestation. However, in most cases these hydrological changes have not been(More)
Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract This paper presents an attempt of simulating daily fluctuations of river discharge at global scale. Total Runoff Integrating Pathways (TRIP) is a global river routing model which can help to isolate(More)
The measurement of spatially distributed water surface elevation (WSE) at the global scale, which is planned by " Surface Water and Ocean Topography (SWOT) mission " , will bring lots of fresh knowledge on global-scale terrestrial water circulation especially when observed WSE is merged into global hydrodynamics modes by data assimilation. In this paper, we(More)
