NAME Homepage: http://www.joss.ucar.edu/name TheThe NorthNorth AmericanAmerican MonsoonMonsoon ExperimentExperiment

• Multiyear, multi-tier research program aimed at studying the sources and limits of predictability of warm season precipitation over N. America • Scientific Objectives: • Improve characterization of warm season convective processes in complex terrain (Tier 1) • Describe and improve simulation of mechanisms controlling intraseasonal variability of the monsoon (Tier 2) • Define the response of the warm season circulation and precipitation to slowly varying boundary conditions (Tier 3) • Improve simulation and prediction of the North American Monsoon System and its variability TheThe NorthNorth AmericanAmerican MonsoonMonsoon Experiment:Experiment: TimelineTimeline ofof ActivitiesActivities
