RISThe Effects of Domain Choice on Summer Precipitation Simulation and Sensitivity in a Regional Climate Model
Publisher: American Meteorological Society
Abstract: Recent results show disagreement between global and limited-area models as to the role of soil moisture feedback during the summer of 1993 in the central United States. July precipitation totals increase by 50% in the ...
Simulation and Sensitivity in a Nested Modeling System for South America. Part I: Reanalyses Boundary Forcing
Publisher: American Meteorological Society
Abstract: A regional climate model driven by reanalyzed atmospheric forcing is used to investigate 1) the large-scale circulation anomalies that were driven by sea surface temperatures (SSTs), which resulted in extreme rainfall ...
Simulation and Sensitivity in a Nested Modeling System for South America. Part II: GCM Boundary Forcing
Publisher: American Meteorological Society
Abstract: A regional climate model driven at the lateral boundaries by ensemble integrations of a general circulation model (GCM) is used to investigate 1) the large-scale circulation anomalies associated with tropical sea surface ...
A Framework for Evaluating Model Credibility for Warm-Season Precipitation in Northeastern North America: A Case Study of CMIP5 Simulations and Projections
Publisher: American Meteorological Society
Abstract: uture projections of northeastern North American warm-season precipitation [June?August (JJA)] indicate substantial uncertainty. Atmospheric processes important to the northeast-region JJA precipitation are identified and ...
Reinitialized versus Continuous Simulations for Regional Climate Downscaling
Publisher: American Meteorological Society
Abstract: The methodology for dynamical climate downscaling is studied using the second-generation regional climate model (RegCM2). The question addressed is, in order to simulate high-resolution details as accurately as possible, ...
The Effect of Regional Climate Model Domain Choice on the Simulation of Tropical Cyclone–Like Vortices in the Southwestern Indian Ocean
Publisher: American Meteorological Society
Abstract: A regional climate model is tested for several domain configurations over the southwestern Indian Ocean to examine the ability of the model to reproduce observed cyclones and their landfalling tracks. The interaction between ...
A Mechanistically Credible, Poleward Shift in Warm-Season Precipitation Projected for the U.S. Southern Great Plains?
Publisher: American Meteorological Society
Abstract: AbstractGlobal and regional climate model ensembles project that the annual cycle of rainfall over the southern Great Plains (SGP) will amplify by midcentury. Models indicate that warm-season precipitation will increase ...
CMIP5 Projected Changes in the Annual Cycle of Precipitation in Monsoon Regions
Publisher: American Meteorological Society
Abstract: nalyses of phase 5 of the Coupled Model Intercomparison Project (CMIP5) experiments show that the global monsoon is expected to increase in area, precipitation, and intensity as the climate system responds to anthropogenic ...
Regional Climate Model–Simulated Timing and Character of Seasonal Rains in South America
Publisher: American Meteorological Society
Abstract: The potential of an experimental nested prediction system to improve the simulation of subseasonal rainfall statistics including daily precipitation intensity, rainy season onset and withdrawal, and the frequency and ...
Monsoon Regimes in the CCSM3
Publisher: American Meteorological Society
Abstract: Simulations of regional monsoon regimes, including the Indian, Australian, West African, South American, and North American monsoons, are described for the T85 version of the Community Climate System Model version 3 (CCSM3) ...
