The Weather Research and Forecasting (WRF) Model is a state of the art mesoscale numerical weather prediction system designed for both atmospheric research and operational forecasting applications. It features two dynamical cores, a data assimilation system, and a software architecture supporting parallel computation and system extensibility.

Support for WRF users & code developers. WRF is now supported through a forum-based platform that can be found in the Weather Research and Forecasting (WRF) Model section on the WRF & MPAS-A Support Forum.

Jul 19, 2024 · WRF Events Bi-annual tutorials are aimed at teaching new users how to use and understand the concepts and mechanisms of the Weather Research and Forecasting (WRF) modeling system. Participants come from the U.S. and around the world.

Aug 24, 2023 · I believe the issue is that you are using a very old version of GNU (V4.8.5) to compile WRF version 4.5.1. Because the compiler is so old, it's not able to compile the newer versions of WRF. Since GNU is free software, can you update to one of …

Mar 24, 2025 · The Mesoscale and Microscale Meteorology Laboratory of NSF NCAR invites you to this year's Joint MPAS/WRF Users' Workshop from June 3 - 6, 2025. The event will take place at the NCAR|UCAR Center Green campus in Boulder, Colorado with a virtual attendance option.

Nov 28, 2023 · The Mesoscale and Microscale Meteorology (MMM) Laboratory at the National Center for Atmospheric Research (NCAR) has led the development and support of WRF-ARW to the community since its inception in the late 1990s.

Sep 7, 2023 · If convenient, please recompile WRF in debug mode, i.e., type ./clean -a in the top WRF directory, then type ./configure -D and ./compile em_real. Once wrf.exe is created, you can rerun this case. The rsl files will tell exactly when and where the model crashed.

Apr 20, 2023 · The WRF Release Committee oversees the major releases of WRF. It is described in the policies for NCAR's administration of the WRF code in WRF Code Repository and Release Administration . The members for the V4.1 release cycle are listed below.

The original development of the WRF system was a joint, long-term effort by a collaboration of organizations. The coordination of the project was shared, and included the partner institutions and outside advisory positions. This page summarizes WRF's historical and …
