Freak Gustnado Mixes With Dirt, Engulfs Town in Iowa – May 4, 2012

Gustnado

Gustnado

This storm was classified as a gustnado. A gustnado is similar to a tornado in the fact that it rotates, but it’s direction is horizontal rather than a vertical like an actual tornado.

The average gustnado lasts a few seconds to a few minutes, although there can be several generations and simultaneous swarms. Most have the winds of an F0 or F1 tornado, and are commonly mistaken for tornadoes. However, unlike tornadoes, the rotating column of air in a gustnado usually does not extend all the way to the base of the thundercloud. Gustnadoes actually have more in common with whirlwinds (which include dust devils, whirlwinds that form due to superheated surface layers and stretched vorticity, most commonly on sunny, warm days with light winds).

    These are technically Plow winds, but bigger. I think Plow wind is the better term here. Still amazing though as to what mother nature can throw at you.

    Here is an excellent example of human behavior in the face of an unknown threat. The desire is to identify what ever is approaching and standing your ground until the last possible moment to do so. Considering how long this took to form a spacific image, there was time to run through the emotional response but in some cases, not until yelled at to get moving into shelter. Kudos to the gal who said, “I had better get my cat and go inside.” I would love to have an aftermath photo of what the dust looked like after the cloud dissapated and the human response to that.

  3. Are we returning to the conditions we had during the time of Dust Bowl in the early 20th century?
