RISInfluence of the Realistic Description of Soil Water-Holding Capacity on the Global Water Cycle in a GCM
Publisher: American Meteorological Society
Abstract: The sensitivity of the hydrological cycle to soil water-holding capacity (WHC) is investigated using the Laboratoire de Meteorologie Dynamique General Circulation Model (LMD GCM) coupled to a land surface model (LSM). A ...
The Impact of Detailed Snow Physics on the Simulation of Snow Cover and Subsurface Thermodynamics at Continental Scales
Publisher: American Meteorological Society
Abstract: The three-layer snow model of Lynch-Stieglitz is coupled to the global catchment-based land surface model of the National Aeronautics and Space Administration?s Seasonal to Interannual Prediction Project, and the combined ...
Introducing Hysteresis in Snow Depletion Curves to Improve the Water Budget of a Land Surface Model in an Alpine Catchment
Publisher: American Meteorological Society
Abstract: he Durance watershed (14 000 km2), located in the French Alps, generates 10% of French hydropower and provides drinking water to 3 million people. The Catchment land surface model (CLSM), a distributed land surface model ...
The Sensitivity of Surface Fluxes to Soil Water Content in Three Land Surface Schemes
Publisher: American Meteorological Society
Abstract: Evaporative fraction (EF; the ratio of latent heat flux to the sum of the latent plus sensible heat fluxes) can be measured in the field to an accuracy of about 10%. In this modeling study, the authors try to determine to ...
Modelling surface runoff and water fluxes over contrasted soils in pastoral Sahel: evaluation of the ALMIP2 land surface models over the Gourma region in Mali
Publisher: American Meteorological Society
Abstract: and surface processes play an important role in the West African monsoon variability. In addition, the evolution of hydrological systems in this region, and particularly the increase of surface water and runoff coefficients ...
Evaluation of Groundwater Simulations in Benin from the ALMIP2 Project
Publisher: American Meteorological Society
Abstract: A comprehensive estimation of water budget components, particularly groundwater storage (GWS) and fluxes, is crucial. In this study, we evaluate the terrestrial water budget of the Donga basin (Benin, West Africa), as ...
Interannual Coupling between Summertime Surface Temperature and Precipitation over Land: Processes and Implications for Climate Change
Publisher: American Meteorological Society
Abstract: idespread negative correlations between summertime-mean temperatures and precipitation over land regions are a well-known feature of terrestrial climate. This behavior has generally been interpreted in the context of soil ...
The AMMA Land Surface Model Intercomparison Project (ALMIP)
Publisher: American Meteorological Society
Abstract: The rainfall over West Africa has been characterized by extreme variability in the last half-century, with prolonged droughts resulting in humanitarian crises. There is, therefore, an urgent need to better understand and ...
Water Balance in the Amazon Basin from a Land Surface Model Ensemble
Publisher: American Meteorological Society
Abstract: espite recent advances in land surface modeling and remote sensing, estimates of the global water budget are still fairly uncertain. This study aims to evaluate the water budget of the Amazon basin based on several ...
