When cold air runs into warm air on a large scale it forms a cold front. If the warm air mass is unstable enough this can trigger thunderstorms, potentially strong ones. Given a few other conditions these storms can begin to rotate and produce tornadoes. Most strong thunderstorms are associated with cold fronts.
However, another significant source of tornadoes. This is a similar scenario to a cold front, only there is a dry air mass pushing into a moist one with little temperature difference. A dry line is even more effective at producing tornadoes than a cold front.
The Arctic and the Antarctica because it's to cold for them to form there!
Hail and tornadoes are most often associated with cold fronts, but can occur with dry lines or, lest often, warm fronts.
Tornadoes most commonly occur in the central United States, within an area known as Tornado Alley. This region includes parts of Texas, Oklahoma, Kansas, and Nebraska. Tornadoes can also occur in other regions around the world, but with less frequency.
The most severe thunderstorms and tornadoes occur in a region of the United States called Tornado Alley, which stretches across the Great Plains from Texas to Iowa.
Tornadoes can occur at any time of year and at any time of day or night. They are merely most common in the spring and early summer and int he late afternoon. In simplest terms, tornadoes most often occur when a cool air mass collides with a warm, moist air mass, triggering thunderstorms. These thunderstorms then encounter wind shear, which gives them the rotation they need to produce tornadoes.
Most tornadoes occur in spring.
Yes. Tornadoes do not occur in Antarctica and likely do no occur in parts of the Arctic and in areas of extreme desert. There are many other regions that are cold or arid that tornadoes occur, but are extremely rare.
Tornadoes can occur in the warm sector of a developing mid-latitude cyclone, typically associated with the cold front. Tornadoes often form along the leading edge of the cold front where warm, moist air is lifted rapidly by the advancing cold air.

No. Although some tornadoes do occur in the winter, most occur during spring and summer.
Tornadoes and other forms of severe weather are most often associated with cold fronts. However, warm fronts and stationary fronts have on occasion produced tornadoes.
Although tornadoes occur in all states, the state with the most tornadoes is Texas.
Most tornadoes occur in spring and summer.
Tornadoes can occur in any season but are most common in the spring.
Tornadoes are most likely to occur in the late afternoon and earl evening.
The most violent tornadoes generally occur in North America.
Most tornadoes are supercell tornadoes.
