Arizona Regional WRF Model Data

Partial support of the Arizona Regional WRF Model has been obtained from Arizona Department of Environmental Quality. The model runs will continue and the forecast discussions will again be available after July 8, as conditions warrant. However, we continue to need other organizations to step up and help support this project via additional computational resources to add to our new dedicated operational model forecast cluster. This will enable larger domain sizes and faster run time speeds. Hardware nodes start at $7K. If interested, please contact Mike Leuthold. A HUGE thanks goes out to ADEQ for their support.

Model Discussion

During the monsoon season and for significant weather events, a model discussion may be available.

The Weather Research and Forecasting (WRF) Model is a next-generation mesocale numerical weather prediction system designed to serve both operational forecasting and atmospheric research needs. Model output is generated using the Department's 448 processor Beowulf cluster with the following configuration:

    WRF Software version 3.3.1              38 vertical σ levels
    Outer Domain: 5.4 km                    Inner Domain: 1.8 km
    WRF Double Moment 6-class Microphysics  RRTMG Radiation
    Noah Land-Surface                       ACM2 Boundary Layer
    

Note: Products have been updated to use Adobe Flash Player. The kmz products are Google Earth overlays of model data. Some kmz files are very large and will take some time for GE to load. The best way to do this is open the configuration window and slow down looping to around 1/4 speed and set the "Loop Animation" option. After a few times through the loop, all images should be loaded. Also, set the "Elevation Exaggeration" option under "Tools->Options to 3. You can also use JPL's Landsat 7 Moasic Imagery as a backdrop."
