Summary
Abstract: Goal: The overall goal of the WRF Model project is to develop a next generation mesoscale forecast model and assimilation system that will advance both the understanding and prediction of important mesoscale weather, and promote closer ties between the research and operational forecasting communities.

The WRF model is being developed as a collaborative effort among the NCAR Mesoscale and Microscale Meteorology Division (MMM), NCEP?s Environmental Modeling Center (EMC), FSL?s Forecast Research Division (FRD), the DoD Air Force Weather Agency (AFWA), the Center for the Analysis and Prediction of Storms (CAPS) at the University of Oklahoma, and the Federal Aviation Administration (FAA), along with the participation of a number of university scientists. Primary funding for MMM participation in WRF is provided by the NSF/USWRP, AFWA, FAA and the DoD High Performance Modernization Office. With this model, we seek to improve the forecast accuracy of significant weather features across scales ranging from cloud to synoptic, with priority emphasis on horizontal grids of 1-10 kilometers. The model will incorporate advanced numerics and data assimilation techniques, multiple relocateable nesting capability and improved physics, particularly for treatment of convection and mesoscale precipitation systems. It will be well suited for a range of applications, from idealized research to operational forecasting, and have flexibility to accommodate future enhancements.

The WRF model has these desirable characteristics: It is designed to be highly modular, and a single source code will be maintained that can be configured for both research and operations. It will be state-of-the-art, transportable, and efficient in a massively parallel computing environment (accommodating vector environments as well). Data assimilation systems and adjoint and tangent linear forms (for 3DVAR analysis and 4DVAR assimilation) will be developed in tandem with the model itself. Numerous physics options will be allowed, thus tapping into the experience of the full modeling community. It will be maintained and supported as a community mesoscale model to facilitate broad use in research, particularly in the university community. Research advances will have a direct path to operations. With these hallmarks, the WRF model is unique in the history of numerical weather prediction in the U.S.

Description: The PSU/NCAR mesoscale model is a limited-area, nonhydrostatic or hydrostatic (Version 2 only), terrain-following sigma-coordinate model designed to simulate or predict mesoscale and regional-scale atmospheric circulation. It has been developed at Penn State and NCAR as a community mesoscale model and is continuously being improved by contributions from users at several universities and government laboratories.
