Recent progress on the North American Monsoon Experiment (NAME) is reported, with emphasis on plans for a NAME Field Campaign during the summer of 2004. NAME is an internationally coordinated, joint CLIVAR-GEWEX process study aimed at determining the sources and limits of predictability of warm season precipitation over North America. It hypothesizes that the North American Monsoon System (NAMS) provides a physical basis for determining the degree of predictability of warm season precipitation over the region. NAME's objectives are to promote a better understanding and more realistic simulation of monsoon evolution and variability, the response of the warm season circulation and precipitation patterns to slowly varying boundary conditions (e.g. SST, soil moisture), the diurnal heating cycle and its relation to the seasonally varying mean climate, and intraseasonal variability of the monsoon. NAME employs a multi-scale (tiered) approach with focused monitoring, diagnostic and modeling activities in the core monsoon region, on the regional-scale and on the continental-scale. The NAME program has strong links between the VAMOS element of International CLIVAR, US CLIVAR Pan American research, and the GEWEX America Prediction Project (GAPP).
