The extreme weather associated with Hurricane Milton has included tornadoes that have killed at least five in Florida’s St. Lucie County, a phenomenon known to occur as such storms move inland.
A tornado is a violently rotating column of air in contact with the surface and a cumuliform cloud base. Tornado formation is caused by the stretching and aggregating/merging of environmental and/or storm-induced vorticity that tightens into an intense vortex. There are various ways this may come about and thus various forms and sub-forms of ...

For a tornado to form in this manner, a rear-flank downdraft enters the center of the mesocyclone from the back. Cold air, being denser than warm air, is able to penetrate the updraft. The combination of the updraft and downdraft completes the development of a tornado. Tornadoes that form in this method are often violent and can last over an ...
Tornadoes are "violently rotating columns of air" in contact with the ground, according to NWS.The humidity in Iowa means as tornadoes form, we see a cloud form inside of them, Gallus explained.
Dust devils form when a pocket of hot air near the surface rises quickly through cooler air above it, forming an updraft. If conditions are just right, the updraft may begin to rotate. As the air rapidly rises, the column of hot air is stretched vertically, thereby moving mass closer to the axis of rotation, which causes intensification of the ...
