WRF Tutorial Overview

Due to COVID-19, the Winter 2022 Weather Research and Forecasting (WRF) tutorial WILL BE HELD VIRTUALLY via Zoom (click here to download Zoom prior to the tutorial).  

The Basic virtual tutorial consists of live abridged lectures on various components of the WRF modeling system, along with live Q&A sessions with instructors, and live hands-on practice sessions. All full-length presentations will be pre-recorded and made available (via YouTube) to attendees two weeks in advance of the tutorial. The agenda (coming soon) will include the presentations/topics for discussion during each Q&A session. Any topics not presented during live sessions each morning should be viewed prior to the Q&A session each day. All sessions will be held during Mountain Standard Times (MST). If you will not be able to attend most live sessions, please do not register, and leave the seat for someone who is able to attend. 

WRF Tutorial Topics

  • WRF Pre-processing System
  • WRF Dynamics and Numerics
  • WRF Physics
  • WRF Software Framework
  • WRF Post-processing and Graphical Tools


Prerequisites for the WRF model are basic knowledge of atmospheric science, numerical modeling, and experience working with a Unix computer environment.

Participants are strongly encouraged to work through the WRF-ARW online tutorial (especially if you are new to WRF), which provides an overview of the system and can help enhance your learning experience during the tutorial.

If you run into any problems while working through this, please post to our WRF/MPAS Support Forum.

Participants are strongly encouraged to become familiar with a Unix/Linux working environment. Using directories, editing text files and Fortran code are essential to operate the modeling system programs. Unix tutorials for beginners can be easily found online, or view the lessons below from The COMET Program

Prior to the tutorial, you will receive a final agenda, along with a link to the pre-recorded tutorial presentations. All live sessions will be conducted through Zoom. If you do not already have Zoom installed on your system, it is advised that you do so as soon as your registration is approved. Some featues in the installed version of Zoom may not be available in the browser version.

You will also need access to a Linux (or Linux-emulating) terminal window on your system, as all work is done in a Linux environment, using Unix commands. Please make sure to install and test this prior to the tutorial.
