Mesoscale Forecast Model (WRF)
Note: Processing 20090509_00Z run... Completed through forecast hour 36
| Note: The mesoscale prognostics depicted on these pages are experimental and may not be available at all times. The accuracy or reliability of the data is not guaranteed nor warranted in any way. The data is provided as is and should not be used as the sole resource for decision making. Mesoscale forecast guidance is best interpreted by a professional meteorologist who is familiar with the particular modeling system, including any model biases. This version of the WRF model is greatly influenced by the 12km NCEP WRF model which provides the boundary conditions. |
Model overview: This version of the Weather Research and Forecasting (WRF) model utilizes the WRF Environmental Modeling System (EMS). The specific model core used is the Advanced Research WRF (ARW) developed by NCAR. The current configuration is on an 172 by 155 grid with 35 vertical levels and runs at an 4-km resolution:
Lambert Conformal Projection
Grid Center Lat-Lon:
24.100, -80.700
Lower Left (SW) Lat-Lon:
21.295, -83.997
Upper Right (NE) Lat-Lon:
26.831, -77.257
Grid Dimensions NXxNY:
172x155
Grid Spacing DX, DY:
4.00km, 4.00km
Number of Grid Points:
26,660
00z initialized start time:
03:15z
12z initialized start time:
15:15z
When available, the WRF will be run 2 times a day at 0000 UTC and 1200 UTC. The model does not start until 3 hours and 15 minutes past the run time in order to acquire initial boundary conditions. The model run and post-processing requires about 8 hours to fully complete. The model output should be available within 120 minutes after the initialized start time. Forecasts are generated out to 36 hours.
