RISAssessing the Influence of Soil Moisture on Seasonal Climate Variability with AGCMs
Publisher: American Meteorological Society
Abstract: Ensembles of boreal summer atmospheric simulations, spanning a 15-yr period (1979?93), are performed with the Action de Recherche Petite Echelle Grande Echelle (ARPEGE) climate model to investigate the possible influence ...
Influence of Soil Moisture on the Asian and African Monsoons. Part II: Interannual Variability
Publisher: American Meteorological Society
Abstract: The relevance of soil moisture (SM) for simulating the interannual climate variability has not been much investigated until recently. Much more attention has been paid on SST anomalies, especially in the Tropics where the ...
Impact of Regional SST Anomalies on the Indian Monsoon Response to Global Warming in the CNRM Climate Model
Publisher: American Meteorological Society
Abstract: While transient climate change experiments with coupled atmosphere?ocean general circulation models undoubtedly represent the most comprehensive tool for studying the climate response to increasing concentrations of ...
A Numerical Sensitivity Study of the Influence of Siberian Snow on the Northern Annular Mode
Publisher: American Meteorological Society
Abstract: he climate version of the general circulation model Action de Recherche Petite Echelle Grande Echelle (ARPEGE-Climat) is used to explore the relationship between the autumn Siberian snow and the subsequent winter northern ...
Influence of Soil Moisture on the Asian and African Monsoons. Part I: Mean Monsoon and Daily Precipitation
Publisher: American Meteorological Society
Abstract: Soil moisture responds to precipitation variability but also affects precipitation through evaporation. This two-way interaction has often been referred to as a positive feedback, since the water added to the land surface ...
Global Evaluation of the ISBA-TRIP Continental Hydrological System. Part II: Uncertainties in River Routing Simulation Related to Flow Velocity and Groundwater Storage
Publisher: American Meteorological Society
Abstract: In the companion paper to this one (Part I), the Interactions between Soil, Biosphere, and Atmosphere?Total Runoff Integrating Pathways (ISBA-TRIP) continental hydrological system of the Centre National de Recherches ...
Trends in Global and Basin-Scale Runoff over the Late Twentieth Century: Methodological Issues and Sources of Uncertainty
Publisher: American Meteorological Society
Abstract: hile human influence has been detected in global and regional surface air temperature, detection?attribution studies of direct (i.e., land use and water management) and indirect (i.e., climate related) effects of human ...
Impact of an Exponential Profile of Saturated Hydraulic Conductivity within the ISBA LSM: Simulations over the Rhône Basin
Publisher: American Meteorological Society
Abstract: This study focuses on the influence of an exponential profile of saturated hydraulic conductivity, ksat, with soil depth on the water budget simulated by the Interaction Soil Biosphere Atmosphere (ISBA) land surface model ...
A Simple Groundwater Scheme for Hydrological and Climate Applications: Description and Offline Evaluation over France
Publisher: American Meteorological Society
Abstract: espite their potential influences on surface water and climate, groundwater processes are generally not represented in climate models. Here, a simple groundwater scheme including two-dimensional flow dynamics and accounting ...
Characterizing GCM Land Surface Schemes to Understand Their Responses to Climate Change
Publisher: American Meteorological Society
Abstract: The impact of land surface representation on GCM simulations of climate change is analyzed using eight climate change experiments, carried out with four GCMs each utilizing two different land surface schemes (LSSs). In the ...
