MPAS-LES

Dudhia: MPAS-LES

1. LES physics is basically three-dimensional turbulence suitable for grids where dx ~ dz
2. Testing SAS Idealized Case
   1. 15-meter grid size - 252720 columns
   2. Top at 3 km (200 levels)
3. Testing on MPAS idealized supercell at 167 m grid size
4. Main code is in new module dynamics/mpas_atm_dissipation_models.F
5. Activated with config_les_model = 'prognostic_1.5_order’
6. Current code is a branch updated to MPAS V8.2.2
7. The plan is to have it in at least a released branch this year

MPAS-UCM

HKUST: MPAS-UCM

1. mesh: 30km-500m
2. generate user defined arbitrary mesh based on geojson file
3. Coupling single UCM in MPAS add LCZ in MPAS
