The air spins violently in the funnel, which is why tornadoes are also given the nickname ‘twister’.
Air flows into the bottom of the funnel very quickly, sucking up buildings, trees, locomotives, cars, and anything else that is in its path.
Strong wind blows ahead of the tornado.
Funnel cloud writhes around, connecting the ground to the bottom of the thundercloud.
 Trade winds –
The trade winds are
so named because of their reliability for trade in times when people relied on sails.
 Tornado – In a tornado winds spiral upwards and inwards to create velocities of several hundred kilometres an hour, making it possible for a tornado to destroy buildings and lift the remains into the air. They are restricted to places with rapidly forming thunderstorms such as ‘Tornado Alley’ that runs across the southern United States.

A government observation network designed to give warning of tornadoes.
Trade winds
Winds that blow constantly from the subtropical highs towards the equator. The trades are caused
by wind flowing out of the high pressure zone at latitude 30° towards the low pressure zone
at the equator. In the Northern Hemisphere the trade winds blow from the northeast (northeast trade winds). In the Southern Hemisphere they blow from the southeast (southeast trade winds). They tend to bring rain when they blow onto an easterly coast and drought when they blow off a westerly coast.
The trade winds are the most reliable winds in the world. In
the days of sailing ships they could be guaranteed to carry ships on their routes carrying goods between countries, hence the name trade winds.
Intense rain falls from a tornado- bearing thunderstorm; thunder and lightning are also common.
