Spatial Distribution of Cordex Regional Climate Models Biases over West Africa

Regional Model Nesting within GFS Daily Forecasts Over West Africa

The study uses the RM3, the regional climate model at the Center for Climate Systems Research of Columbia University and the NASA/Goddard Institute for Space Studies (CCSR/GISS). The paper evaluates 30 48-hour RM3 weather forecasts over West Africa during September 2006 made on a 0.5° grid nested within 1° Global Forecast System (GFS) global forecasts. September 2006 was the Special Observing P...

Spatial Distributions of Precipitation Events from Regional Climate Models

The Institute of Mathematics Applied to Geosciences (IMAGe) and the National Center for Atmospheric Research (NCAR) has an active research program in the statistical analysis of large numerical simulation of the climate over North America. What is unique about these simulations is their high resolution (50 km) which approaches the scale needed to assess local effects of climate change. The goal...

A spatial analysis of multivariate output from regional climate models

Climate models have become an important tool in the study of climate and climate change, and ensemble experiments consisting of multiple climate-model runs are used in studying and quantifying the uncertainty in climate-model output. However, there are often only a limited number of model runs available for a particular experiment, and one of the statistical challenges is to characterize the di...

CORDEX – An international climate downscaling initiative

The World Climate Research Programme (WCRP) is backing an international initiative called the COordinated Regional climate Downscaling EXperiment (CORDEX). The goal of the initiative is to provide regionally downscaled climate projections for most land regions of the globe, as a compliment to the global climate model projections performed within the fifth Coupled Model Intercomparison Project (...
