A tornado is a violent windstorm characterized by
a twisting, funnel-shaped cloud. The word
"tornado" comes from the Spanish or Portuguese
verb tornar, meaning "to turn."
Tornadoes form in
storms all around the world, most famously in a
broad area of the American Midwest and South known
as Tornado Alley. Meteorologists don't know
exactly why we have tornadoes, but they do know
that they usually start when there is a bad
thunderstorm with hail and lightning.
thunderstorm forms, a change in wind direction and
a rapid increase in wind speed, with increasing
height above the earth's surface create an
invisible horizontal spinning effect in the lower
atmosphere. Warm air from the ocean meets cold
air from the north. When they meet, the warm air
rises above the cold air. The colder air falls to
the ground. The warm air then cools and forms a
convection cell. These cells can start to spin at
near 300 mph, causing the winds of the tornado. As
it spins it picks up dirt and water droplets which
form the famous and trademark funnel of a
Tornadoes start during the warmest
or most humid part of the day which would be
between 4:00 pm and 6:00 pm . The cold air that
gets trapped in the warm air will form a dark big
black cloud that has air spinning inside.
