  • Ahlfeld, D.P., 2006: Comparison of Climate Model Precipitation Forecasts with North American Observations. Proc. XVI Int. Conf. on Computational Methods in Water Resources.

A comparison is made between observed and forecasted precipitation from 18 global climate models for the period 1979 to 2000 in three regions of North America. The comparison is motivated by an interest in the potential for global climate models to serve as practical tools for water resource planners. Precipitation averaged over monthly, seasonal and annual time periods is considered. The three regions encompass western, central and eastern North America excluding Alaska, northern Canada and Latin America. Most models compare well with observed precipitation for the central and eastern regions at all time scales. For the western region, all models over-predict precipitation at most time scales. Further improvements in GCMs can be expected from the climate modeling community. New methods are needed to better assimilate the inter-model variability of GCM output to create useful information products for water resource planners
