WRF Physics Improvements

Incorporation of three contributed codes into WRF physics.

  • DOE CRM (Department of Energy Cloud Resolving Model)
    • utilizes WRF as a CRM/LES using doubly periodic lateral boundaries
  • NTU physics (National Taiwan University microphysics)
    • is a multi-moment four-ice (pristine ice, aggregate, graupel, and hail) bulk microphysical scheme
  • WRF electrification
    • explicit charging/discharge model implemented into the NSSL(*) two-moment microphysics scheme

(*) NSSL: National Severe Storms Laboratory

Readers and data converters

Three new readers and data converters added in the development release. These tools facilitate the accessibility of reanalysis data sets for use within NU-WRF.

Updated pre-processing system

The following utilities test the physics scheme in off-line (no dynamics integration) mode.

  • GMP: Goddard MicroPhysics off-line testbed
  • GRAD: Goddard RADiation off-line test bed
