WRF offers two dynamical solvers for its computation of the atmospheric governing equations, and the variants of the model are known as WRF-ARW (Advanced Research WRF) and WRF-NMM (Nonhydrostatic Mesoscale Model). The Advanced Research WRF (ARW) is supported to the community by the NCAR Mesoscale and Microscale Meteorology Division. The WRF-NMM solver variant was based on the Eta Model, and later Nonhydrostatic Mesoscale Model, developed at NCEP. The WRF-NMM (NMM) is supported to the community by the Developmental Testbed Center (DTC).

The WRF serves as the basis for the [[North American Mesoscale Model]] and the [[Rapid Refresh]] model, two operational forecast models run regularly at NCEP.

A version of WRF-NMM tailored for hurricane forecasting, [[Hurricane Weather Research and Forecasting model|HWRF]] (Hurricane Weather Research and Forecasting), became operational in 2007.<ref>{{Cite web|url=http://www.noaanews.noaa.gov/stories2007/s2885.htm |publisher=NOAA News Online |title=New Advanced Hurricane Model Aids NOAA Forecasters |date=27 June 2007 |accessdate=27 June 2010 }}</ref>
