Tornadoes are created when strong, rising whirlwinds are formed alongside storm clouds. Tornadoes are especially common in North America. In the United States, tronadoes mostly occur in the spring.

A tornado is a storm that has a rotating cone shape. Its diameter can range from tens of meters to hundreds of meters. If a tornado touches land or water, it can suck material into itself. Tornadoes are short-term climatic phenomena: their time frame ranges from a couple of minutes to a couple of hours.
