Model Overview: The 9km and 3km runs are from the Weather Research and Forecasting (WRF) model utilizing the WRF Environmental Modeling System (EMS, Version 3.4). The specific model core used for these simulations is the Advanced Research WRF (ARW). This configuration is set up as a 2-way nest with a 9km outer domain covering much of the state and a 3km resolution inner domain covering southern Florida. Both runs have 45 vertical levels. The models run with no cumulus parameterization, so that convection is explicit. 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 60 minutes to complete. Therefore model output should be available within 1 1/2 hours after the initial time This version of the WRF-ARW uses the Rapid Refresh model (RAP) to initialize the model (hot start). The RAP generates analyses that combine in situ and remote data sets to depict the current state of the atmosphere. High resolution MODIS satellite data is used to depict the sea surface temperatures within the initial conditions of the model. A high resolution Land Information System (LIS) is also used for initial conditions. Lateral boundary conditions are provided by the 12km North American Mesoscale model (NAM).

 

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.
