savage swirling winds
Tornadoes usually form in a giant rotating thunderstorm called a supercell. Supercells form when cold polar air meets warm tropical air. The result is a great instability caused by the rising warm air. A squall line, or narrow zone of cumulonimbus clouds forms, giving life to the tornadoes.
Tornadoes can cause a lot of destruction and it can cost millions of dollars in repair damage. It can leave people without homes and even without a family member or more than one.
