Overview

The Weather Research and Forecasting (WRF) model is a next-generation mesoscale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. It features multiple dynamical cores, a 3-dimensional variational (3DVAR) data assimilation system, and a software architecture allowing for computational parallelism and system extensibility. WRF is suitable for a broad spectrum of applications and across scales ranging from meters to thousands of kilometres.

If you have any corrections, comments or contributions, please feel free to email us on cws_help@nci.org.au so that we can continue to update and upgrade the guides over time.

The installation (obtaining and compiling the source code) is NCI specific. The NCAR guides which we link to give instructions for compilation. DO NOT USE THOSE INSTRUCTIONS. They will not work. First, install WRF using this wiki's instructions and only follow the NCAR guides for running your simulation.

Updates

11 May 2020: New WRF version

Versions affected:

None

Description Version v4.2 is now ready to be used on Gadi. Note, WPS and WRF have been updated. I have also renamed the WRFV3/ directory to WRF/.

05 March 2020: ERA-Interim

Versions affected:

  • V3.9
  • V3.9.1.1
  • V4.0.2
  • V4.1.1
  • V4.1.2
  • V4.1.3
  • V4.1.4

Description wps-era has now been ported to Gadi for these versions. Note the code is using a new METGRID.TBL: METGRID.TBL.ERAI. This file has been corrected in WRF/WPS/metgrid.

This file is not distributed with standard WRF but is in the code base ported to Gadi.

Please clone wps-era and update your WRF code to use this capability.

Compilation No compilation is required after updating the code.

03 March 2020: Bug

Versions affected:

  • V4.1.1
  • V4.1.2
  • V4.1.3
  • V4.1.4

Issue description: An error has been found that affect the January 2000 case from the NCAR tutorial. In order to run this case, you will now need to use the Variable Table: Vtable.GFS.tutorial for ungrib.exe.

Compilation: No compilation is required after updating the code base from Github.

Installation Guide

For all versions, you will now find the code on Github. Please follow the instructions in the README for the branch corresponding to the version you want to use.
