This study analyzes projections of summer precipitation over the Southeastern United States under the A2 climate scenario using the Community Climate System Model Version3 (CCSM3), and the Regional Spectral Model (RSM) forced with CCSM3 output. The CCSM3 projects a dipole in precipitation, while the RSM projects a universal drying of the Southeast. The difference in patterns of projected rainfall is explained through the RSM's depiction of the diurnal variance of precipitation, which according to observations can account for up to 40% of total seasonal variance in precipitation. The CCSM3 pattern is attributed to an exaggeration of the "upped ante" mechanism, whereby the atmospheric boundary layer (ABL) moisture required for convection to occur increases in a warmed environment. Also contributing to the drying of both models is an expansion of the North Atlantic subtropical high (NASH).
