Very often they do. Tornadoes typically form along from thunderstorms that occur along or near a cold front (where cold air pushes into warm air) or dry line (where dry air pushes into moist air). However tornadoes can also form in the absence of boundaries such as in the outer rain bands of a hurricane.
Tornadoes typically form within thunderstorms as a result of strong updrafts and wind shear. It is rare but possible for tornadoes to form without a thunderstorm, such as in the case of landspout tornadoes which develop from different processes, like boundaries of air masses colliding.
Yes, tornadoes can form. Hundreds, even thousands of tornadoes form every year.
Tornadoes can form in mountains, but most do not.
No. Tornadoes form from cumulonimbus clouds.
Antarctica is too cold for tornadoes to form. Tornadoes need energy from warm air.
Yes. Tornadoes form from the clouds of a thunderstorm.
Tornadoes most often form on land, but they can form over water.
No it does not come from tornadoes . :] .....
Tornadoes need thunderstorms to form.
Tornadoes mostly form from cumulonimbus clouds. :D
Tornadoes usually form from a type of thunderstorm called a supercell. Tornadoes themselves are a unique type of windstorm.
While they happen everywhere else, tornadoes are not known to form in Antarctica.
