Model Description: The Weather Research and Forecasting (WRF) Model is a next-generation mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. This model was developed in a collaborative partnership of the National Center for Atmospheric Research (NCAR), the National Oceanic and Atmospheric Administration (represented by the National Centers for Environmental Prediction (NCEP) and the Earth System Research Laboratory), the U.S. Air Force, the Naval Research Laboratory, the University of Oklahoma, and the Federal Aviation Administration (FAA). WRF can be used in two configurations: either in the “real”, full-physics configuration or in the “idealized”, dry configuration. An important aspect is its ability to simulate the atmosphere from the ground up to 80 km at high horizontal resolutions (e.g. 1km). In WAVE we will take advantage of an idealized WRF setup developed at NWRA that inputs latent heating derived from observations and simulates a large portion of the convective gravity wave spectrum up to the mesosphere.
