Tornadoes often begin as funnel clouds with no associated strong winds at the surface, and not all funnel clouds evolve into tornadoes. Most tornadoes produce strong winds at the surface while the visible funnel is still above the ground, so it is difficult to discern the difference between a funnel cloud and a tornado from a distance.

Some of the most notorious twisters in U.S. history were wedge tornadoes, including the EF5 that leveled Joplin, Missouri, on May 22, 2011, and the El Reno tornado, which was a jaw-dropping 2.6 ...
"In the original Twister, the idea of putting these Dorothy sensor balls into a tornado is completely science fiction, but it inspired a generation of people to want to do scientific research on ...
They are comparable to tornadoes in that both are a weather phenomenon involving a vertically oriented rotating column of wind. Most tornadoes are associated with a larger parent circulation, the mesocyclone on the back of a supercell thunderstorm. Dust devils form as a swirling updraft under sunny conditions during fair weather, rarely coming ...
None of the tornadoes in the United States recorded before February 1, 2007, were re-categorized during and after the transition to the EF Scale. Essentially, there is no functional difference in how tornadoes are rated. The old ratings and new ratings are smoothly connected with a linear formula.
CGI technology has, of course, made quantum leaps since you worked on "Twister" 18 years ago. One tornado in "Twisters" probably took as much computing power as we used to make the whole of the ...
A fire whirl, fire devil or fire tornado is a whirlwind induced by a fire and often (at least partially) composed of flame or ash. These start with a whirl of wind , often made visible by smoke , and may occur when intense rising heat and turbulent wind conditions combine to form whirling eddies of air.
What is the difference between an EF-1 and EF-2 tornado? Tornadoes differ by wind speeds and amount of damage. On the EF Scale, an EF-2 tornado is more severe than an EF-1, with 111 to 135 mph winds.
