Severe thunderstorms
No, tornadoes typically form over land in association with thunderstorms. Waterspouts, which are tornadoes that form over water, can occur in tropical oceans under specific conditions, but they are generally much weaker than tornadoes that form over land.
Tornadoes can form in mountains, but most do not.
Tornadoes can form at any time of day or night. The time from 3 PM to 9 PM is the most common time for tornadoes to form.
No, some tornadoes will form without a wall cloud. In most cases there are of a variety called landspouts, which are tornadoes that do not form in association with the mesocyclone of a supercell. These tornadoes are typically weak, though on occasion have been known to cause damage as high as F3.
Yes. Tornadoes typically form in the afternoon or early evening as that is when the atmosphere is usually most unstable.
Most tornadoes are associate with a kind of thunderstorm called a supercell.
No, tornadoes typically form over land in association with thunderstorms. Waterspouts, which are tornadoes that form over water, can occur in tropical oceans under specific conditions, but they are generally much weaker than tornadoes that form over land.
Tornadoes can form in mountains, but most do not.
Tornadoes are least likely to form in association with a warm front, though it can happen.
Tornadoes most often form on land, but they can form over water.
Tornadoes most frequently form on the Great Plains in the United States.
Most tornadoes are produced by thunderstorms called supercells, though occasionally tornadoes form in squall lines.
Yes. Tornadoes are the most dangerous form of severe weather.

Tornadoes can form at any time of day or night. The time from 3 PM to 9 PM is the most common time for tornadoes to form.
Yes. While tornadoes can form in any season they are most common in the spring.
Cold fronts are most often associated with the formation of tornadoes. As a cold front moves in, it can lift warm, moist air rapidly, creating the unstable conditions necessary for tornado development. The contrast in temperature and moisture along a cold front can promote the formation of supercell thunderstorms, which are more likely to produce tornadoes.
