Weather Research and Forecasting model
- Weather Research and Forecasting model
The Weather Research and Forecasting (WRF) model is a specific computer program with a dual use for forecasting and research. It is the latest numerical program model to be adopted by the National Weather Service as well as the U.S. military and private meteorological services. It is also being adopted by meteorological services worldwide. It is based on the Eta model made by Zaviša Janjić and Fedor Mesinger.
A specialized version of the program, the Hurricane Weather Research and Forecasting (HWRF) model became operational in 2007. [ [http://www.noaanews.noaa.gov/stories2007/s2885.htm NOAA News Online (Story 2885) ] ]
The WRF is a mesoscale model that uses a grid spacing between 4 and 12.5 kilometers, with vertical grid spacing between 25 and 37 divisions. There are two distinct varieties of this model; the "Advanced Research WRF" or ARW (a recursive acronym) is used for research purposes and the "Nonhydrostatic Mesoscale Model" or NMM is used for operational purposes. Versions of the NMM are run at various National Weather Service offices, colleges, and universities in the United States over relatively small regions, usually with the higher 4 km grid spacing.
