Tornadoes are formed when warm air combines into storm clouds causing an updraft that mixes with a burst of colder air, which leads to rotation within the cloud. The down draft of cooler air causes the tornado to form, p... More »

Although science is very advanced, there is not enough data to fully understand all the reasons behind tornado formation, but they are believed to occur when rotating thunderstorms form mesocyclones. Once the mesocyclone... More »

Tornadoes form when unstable air in a thunderstorm creates a horizontal rotation in the clouds and strong downdrafts draw that vortex down to the ground. Overlapping fronts can trigger the wind shear necessary to initiat... More »

According to the National Oceanographic and Atmospheric Administration, tornadoes form when warm air creates a rotating updraft in a powerful thunderstorm. When winds blow in sharply different directions or at different ... More »

Twisters, or tornadoes, form during super cell thunderstorms in which a column of air rotates, according to The National Center of Atmospheric Research. The air increases speed in an updraft of the thunderstorm, and a fu... More »

Most tornadoes are created as a result of thunderstorms that form at the meeting point between humid air from the Gulf of Mexico and dry, cooler air from Canada. At that point, instability occurs in the atmosphere, and a... More »

Tornadoes are typically identified as a violently rotating column of air that extends from the bottom of a cumuliform cloud to the ground. Hurricanes, on the other hand, are tropical storms that generate heat and have st... More »
