CSDMS 2.0: Moving Forward

Introduction to the Weather Research & Forecasting (WRF) System, a High-Resolution Atmospheric Model

[[CSDMS meeting abstract presentation::WRF is a highly parallel state-of-the-art numerical weather prediction model hosted by the National Center for Atmospheric Research (NCAR). This community model was designed from the onset to be fairly flexible, supporting both operational forecasting and atmospheric research needs at scales ranging from meters to thousands of kilometers. Given the model’s physics implementation and it’s modular design, WRF naturally became the core for a number of more specialized models, including: HWRF (used to forecast the track and intensity of tropical cyclones), WRF-CHEM (simulates the emission, transport, mixing, and chemical transformation of trace gases and aerosols simultaneously with meteorology), Polar WRF (a version of WRF optimized for the polar regions), CWRF and CLWRF (versions of WRF modified to enable regional climate modeling), and planetWRF (a general purpose numerical model for planetary atmospheres used thus far for Mars, Venus, and Titan).

The goal of this clinic is to provide an overview of the WRF model, including: model architecture, physics options, data required to drive the model, standard model output, model applications, and system requirements. Several examples will be presented. A Basic Model Interface (BMI) is currently being developed for WRF to facilitate the coupling of this atmospheric model with other earth system models.
