Wind is another way of Mother Nature to show her anger. It can come out of nowhere and blow everything out of its way. Wind is simply the flow of air from higher pressure region to lower pressure region. If the air pressure difference is high we get high speed wind. We observe the devastating force of wind in the form of tornado. Tornado is created when hot air is trapped under the cold air. As atmosphere tries to balance things, it creates violent vortex of air known as tornado. It has the ability to rip off the building from its foundation.
