Model: WRF NMM V3.0

Overview

The WRF model is designed to be a flexible, state-of-the-art, portable code that offers two dynamic solvers and numerous physics options. The Nonhydrostatic Mesoscale Model utilizes the Arakawa E grid on a rotated latitude-longitude projection and a pressure-sigma hybrid vertical coordinate. For this test, the NMM is configured with one static nest and either one or two moving, two-way interactive nested domains. For more detailed information, please see the NMM Users Guide
