The Weather and Climate Group (WCG) at the NOAA Center for Atmospheric Sciences (NCAS) conducts research aimed mainly at improving National Weather Service (NWS) forecast accuracy of precipitation, from studies designed to increase our understanding of model physical processes, and improved data assimilation methodologies. Specifically NCAS research efforts focus on improving physical parameterization schemes of Planetary Boundary Layers (PBL) and surface layer processes, convection, and cloud aerosol effects on radiative transfer of atmosphere (forward models) for NOAA operational models, and improving the understanding of tropical cyclogenesis processes, and prediction of track, and intensity of tropical storms. Members of WCG have expertise in atmosphere, ocean and coupled modeling; in the diagnostics of the atmosphere and ocean; and in the analytic description of the climate system.

Some examples of research areas of the WCG include:

  • Climate and weather analyses and prediction
  • Surface-Atmospheric interactions and PBL processes
  • Cloud-aerosol effects
  • Evaluation of HWRF during hurricane landfalls
  • Development of regional climate models
  • AMMA Experiment and Numerical Modeling Investigations
  • Validation and improvement of CRTM
  • Design and operation of observing systems for climate monitoring.

Members of the WCG are active participants in both national and international weather and climate programs. For more information about the WCG, please see the latest annual report of the NOAA Center for Atmospheric Sciences.
