Description

Develop physical parameterizations of turbulence within MPAS/WRF/CCPP for use in NWS operational forecast products. Work with NOAA/GSL scientists to improve the MYNN-EDMF moist-turbulent boundary layer scheme within the HRRR physics suite for future forecast applications such as RRFS, GFS, or sub-1km grid spacing applications. The research topics of interest include:

Cloud-turbulence-radiation interactions
Low-level shear and stable boundary layers
Coupling to ocean models
3D extension of the MYNN-EDMF for use in large-eddy simulations
Tropical boundary layers and the representation of turbulence in hurricane forecasts
Parameterizing subgrid-scale plumes (convective updrafts or negatively buoyant downdrafts) in the MYNN-EDMF
Coupling of boundary layer schemes to surface layer schemes/land surface models.
