Introduction to Tornado

Vertically rotating air which one end is touching the ground and other is toward the sky is usually known as Tornado. Mostly tornadoes are funnel shaped air storms. Tornadoes are also called twisters and cyclones.

The USA has more tornadoes than any other country in the world, averaging around 1200 a year. “Tornado Alley” is an area in central USA which is frequently hit by tornadoes.

Tornadoes can be detected before or as they occur through the use of Pulse-Doppler radar by recognizing patterns in velocity and reflectivity data.
