How A Tornado Originates And Its Features?

A tornado is a Spanish word that means to twist or to turn. The word might not have as grave a meaning as what it depicts as one of the killer vehicles that nature employs that leaves widespread destruction in its path. As per definition, a tornado is usually caused due to the extremely low pressure that develops and a whirlwind that is created as a result. This results in a thunderstorm of severe levels.

Tornado winds have certain characteristics. For instance, they wind in such a storm usually turn in a counterclockwise direction. Funnel shaped columns of winds are formed in tornadoes, but these are not seen by the naked eye. The winds that rotate usually turn in a counterclockwise direction and touch the ground. However, what is visible to the eye is not the wind movement, but when debris is pulled up and swirled by these strong winds.  The conditions of a violent tornado storm are usually picked up on weather detection system radars.
