Observing and Understanding the Variability of Water in Weather and Climate


Overview of the North American Monsoon Experiment (NAME)

Wayne Higgins, NOAA/NWS/NCEP/CPC, Camp Springs, MD

Recent progress on the North American Monsoon Experiment (NAME) is reviewed, with emphasis on plans for a NAME Field Campaign during the NH 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 employs a multi-scale (tiered) approach with focused activities in the core monsoon region (Tier 1), on the regional-scale (Tier 2) and on the continental-scale (Tier 3). NAME’s objectives are to promote a better understanding and more realistic simulation of: warm season convective processes in complex terrain (Tier 1); the intraseasonal variability of the monsoon (Tier 2); and the response of the warm season precipitation pattern to slowly varying oceanic and continental boundary conditions (Tier 3). The NAME program has strong links between the VAMOS element of International CLIVAR, US CLIVAR Pan American research, and the GEWEX Americas Prediction Project (GAPP).
