Wind damage – this time no flood!

As Sop reported, weather was the big  story here over the weekend.  Governor Barbour described the damage in his home county of Yazoo as looking “like Katrina”.  This photograph, found in the Clarion Ledger’s excellent coverage of the story, is an example of the Katrina-like damage the Governor could see from his helicopter view.

Without any doubt, a tornado is a windstorm; but, What is a Tornado? points out  common misunderstanding about these deadly storms – and the  photograph that follows, one Sop took after Katrina,  points out Governor Barbour was right when he claimed the tornado damage was a Katrina-look-alike:

Tornado — 1. A violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud.

Since it is the wind associated with the rotating air column that does the damage, it is the moving air (wind) and not the cloud that constitutes the tornado…. (Doswell, Cooperative Institute for Mesoscale Meteorological Studies; Norman, Oklahoma)

Two look-alike photographs of damage – one from each storm.  Can you guess which storm caused the damage in the photograph below the jump? Continue reading “Wind damage – this time no flood!”
