| The MPAS group in MMM/NCAR
is performing an going real-time prediction experiment with
MPAS-Atmosphere. We are producing daily 10 day forecasts
initialized at 00 UTC from the operational GFS analysis using our
standard 60-15 km mesh that we have used in our tropical cyclone
forecast experiments, but here the mesh is centered over North America. |
| The 15 km
mesh uses 2,621,442 cells to tile the sphere (i.e. cells on a
horizontal plane), and the variable-resolution meshes use 535,554 cells
to tile the sphere. The physics used in these forecasts, taken
from the WRF model, are Surface Layer: (Monin Obukhov): module_sf_sfclay.F as in WRF 3.7. PBL: YSU as in WRF 3.8. Land Surface Model (NOAH 4-layers): as in WRF 3.3.1. Gravity Wave Drag: YSU gravity wave drag scheme. Convection: new Tiedtke, as in WRFV3.8 Microphysics: WSM6: as in WRF 3.5 Radiation: RRTMG sw as in WRF 3.4.1; RRTMG lw as in WRF 3.4.1 Ocean Mixed Layer: modified from WRFV3.6 |
