North American Mesoscale Model

The North American Mesoscale Model (NAM) refers to a numerical weather prediction model run by National Centers for Environmental Prediction for short-term weather forecasting. Currently, the Weather Research and Forecasting Non-hydrostatic Mesoscale Model (WRF-NMM) model is run as the NAM, thus, three names (NAM, WRF, or NMM) typically refer to the same model output. The WRF replaced the Eta model on June 13, 2006.[1] The model is run four times a day (00, 06, 12, 18 UTC) out to 84 hours. It is currently run with 12 km horizontal resolution and with three-hour temporal resolution, providing finer detail than other operational forecast models. The NAM ensemble is known as the Short Range Ensemble Forecast (SREF) and runs out 87 hours.
