* Most tornadic storms rotate cyclonically, but a few rotate anticyclonically.
* is in southern Kansas.

Weaker storm
* are more likely to strengthen after transition.
* travel roughly with the winds aloft.

Windstorm
* associates with convection.
* can easily stir-up the uppermost sediment layer of the bottom in the pelagic zones.
* cause much avoidable loss of life and property
* cleanse the world of debris, and changes the focus of the path.
* includes storm centers.
* rise very quickly and can blow unabated for a day or more.
* sometimes move the dust, resulting in both seasonal and long-term changes.
* usually occur in late winter to early spring when warm and cold air collide.
