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 ...
Tornadoes can occur anywhere in the U.S., according to the National Weather Service.Tornadoes are “most common in the central plains east of the Rocky Mountains and west of the Appalachians.”
The reason for the peak period for tornado formation in North America being skewed toward spring has much to do with temperature patterns in the U.S. Tornadoes often form when cool, polar air traveling southeastward from the Rocky Mountains overrides warm, moist, unstable Gulf of Mexico air in the eastern states. Tornadoes tend to be commonly ...
These tornadoes may form at different times or exist simultaneously but are separate from one another. A phenomenon similar to multiple vortices is the satellite tornado . Unlike the multiple-vortex tornado, where smaller vortices form inside the main tornado, a satellite tornado develops outside the main tornado's circulation.
Tornadoes can form any time the conditions are right. They take many shapes, but they all start the exact same way. Here's what to know.
Meteorologists still do not know the exact mechanisms by which most tornadoes form, and occasional tornadoes still strike without a tornado warning being issued. [142] Analysis of observations including both stationary and mobile (surface and aerial) in-situ and remote sensing (passive and active) instruments generates new ideas and refines ...
Tornadoes are some of the most extreme weather events on Earth, and just like snowflakes, no two tornadoes are the same. No matter their shape or size, every type of twister can be dangerous, with ...
