Where do tornadoes come from? How do they form? Power of 5 meteorologist Trent Magill explains...
Most of the tornadoes that happen in the world occur in the United States, and there are a couple of reasons why. Gulf moisture from the south meets cool, dry Canadian air from the north, and that collision sets up a zone known as Tornado Alley. The cooler, dryer air dives underneath the moist air, lifting it up, which causes thunderstorms.
Tornadoes occur when the wind above and below changes direction. When warm air on the surface rolls in with the cold air above it, that change in direction causes a horizontal rotation. Warm air wants to rise, so it lifts the rotation upwards into a thunderstorm, which turns the horizontal rotation into a vertical rotation.
Ohio does not get as many tornadoes as other parts of the country, but we do get them.
