20th Anniversary Of The August 18, 2005 Tornado Outbreak - Revisiting The Largest Tornado Outbreak In Wisconsin State History

Prior to the seasonal green-up, land management agencies engage in a lot of prescribed burning to help promote a healthy and sometimes safer ecology. The Horicon Marsh area up in northern Dodge county is an active place for prescribed, or controlled burns. One fire on, Thursday, April 23, was generating a large smoke plume that was clearly visible from our tower camera and was picked up by our WSR-88D doppler radar.

Here's the view looking north from the tower camera:

Here's the view from the radar:

We can use this example as a training exercise to run the NOAA HYSPIT model. If this were a hazardous materials release that generated a potentially dangerous plume, the HYSPLIT model could give us a good idea where the plume is headed and what the dispersion concentrations would be. We would be working closely with state and local emergency management to help inform the public of any possible dangers. So, with that in mind, here an animation of the smoke plume using the HYSPLIT model. It looks like a reasonable approximation!
