Mesoscale Modeling (Code 7533)
Section Head: 7533@nrlmry.navy.mil

The Mesoscale Modeling Section develops and applies computer models for the dynamic prediction of atmospheric and oceanographic variables and for fundamental investigations of regional-scale environmental processes, with emphasis on coastal environments, topographic effects, and air/sea/land interactions. The primary models of interest are the NRL-developed Coupled Ocean/Atmosphere Mesoscale Prediction System (COAMPS™) and the NRL Coastal Ocean Model (NCOM) .

The Mesoscale Modeling Section is working in these main areas:
  • Nonhydrostatic Mesoscale Model Development
    • Operational improvements to COAMPS™ for central site and on-scene prediction.
    • Atmosphere/ocean circulation/ocean wave coupling.
    • Land surface modeling and urban effects.
    • Representation of sub-grid-scale orography.
    • Sea-surface temperature analysis.
    • Embedded aerosol modeling.
    • Physical parameterization development (surface layer, boundary layer, turbulence closures, convection, cloud/aerosol microphysics, radiation).
    • Dynamical core development (dynamically moving nested grids, lateral and upper boundary conditions, numerical methods for nonhydrostatic models).
    • Implementation of software on scalable computer architectures (Message Passing Interface).

    • Refractive effects.
    • Electromagnetic wave propagation.
    • Tropical cyclone structure and intensity forecasting.
    • Dynamical forcing of aerosol events.
