Tornadoes are considered the most violent weather on the Earth's surface, resulting in a visible (or invisible) rotating (vortex) column of air extending from a cumulonimbus cloud to the surface as a funnel cloud. Most of the time tornadoes are visible because they condense water vapor, dust, and debris. They have many names such as twisters, whirlwinds or cyclones, but they are  a low-pressure system with counterclockwise circulation in the Northern Hemisphere.
