Tornadoes are known as one of the most
damaging dosasters. What is the description of tornadoes? A tornado is a very
powerful column of winds which spirials around a center of low atmospheric
pressure. A tornado will look like a large black funnel which down from a strom
cloud.
The name “Tornado” derives from the
Latin “tonare”. It means “to thunder”. While the Spanish developed the word
into “tornear” which means “to turn or twist”. This is why a tornado is
sometimes called twister or cyclone.
The winds inside a twister can spin
around at speeds up to 500 miles an hour, but usually travels at roughly 300
miles an hour. This speed twisting makes a tornado the most dangerous storm.
The avarage tornado has a diameter of
about 200 to 300 yards. The smaller tornadoes are known as satelite tornadoes.
These small offspring, about 50 yards across, can be very fierce and do lots of
damage.
The forming of tornado can be very
quick. Sometimes it can form in a minutes or less. A tornado can travel across
the ground at high sppeds, then it can suddenly vanish. Most tornadoes last
less than twenty minutes and travel less than 15 miles. However, the super
stroms sometimes travel over 100 miles before they are exhaused.
