TORNADO

Tornado is a violent, rotation column of air which is in contact with both the surface of the earth and a culumlonimbus cloud. The tornado comes in different shapes and sizes.It is visible, because of the intense low pressure which causes the high wind speed and rapid rotation, which usually cause water vapour in the air.

A single storm will produce more than one tornado. There are variety types of tornadoes that exist around the world. Tornado have been observed on every continent except Antartica. Majority of tornadoes in the world occur in the Tornado Alley region of the United States. Most common tornado that occur is Waterspouts, a spiraling funnel shaped wind current that form over a body of water. Further more, tornadic waterspouts are stronger over water.

Tornadoes normally rotate cyclonically due to the thunderstorms, which are so small that could influence to a massive vortex. Tornadoes influence by emit on the electromagnatic spectrum, which lightning activity decrease as a tornado reaches the surface and returns to the baseline level when the tornado lifts.

There are various type of tornadoes that existed in nature, that comes in many shapes and sizes. They occasionally occur in the western part of the earth. And could be detected by using Pulse-Doppler radar, which is by, recognizing patterns in velocity and reflectivity data.
