Mesoscale Forecast Model (WRF)
Latest run: 20080919_21Z
| 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 LAPS analyses, and the quality of the NMM model that 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 Non-hydrostatic Mesoscale Model developed by the National Center for Environmental Prediction (NCEP). The current configuration is on an 95 by 151 grid with 35 vertical levels and runs at an 4-km resolution. When available, the WRF will be run 4 times a day at 03, 09, 15, and 21 UTC. The model does not start until about 35 minutes past the start time in order to acquire initial and boundary conditions. The model run and post-processing require about 120 minutes to complete. Therefore model output should be available within 2 1/2 hours after the initial time. Forecasts are generated out to 27 hours. This version of the WRF-NMM uses the Local Analysis and Prediction System (LAPS) to initialize the model (hot start). LAPS generates analyses that combine in situ and remote data sets to depict the current state of the atmosphere.
