1) severe thunderstorms occur when dry cold air comes
into contact with warm moist air.
2) When a thunderstorm occurs a horzontal colum of wind
forms.When that colum of air meets updrafts the horizontal wind starts
to lift and becomes vertical.Then the tornado forms.
3)The average tornado only stays on the ground about
three to five minutes at a time.
4) Warning times for tornados,in most locations,is only
about three minutes.
5) Most tornados form out of a special type of thunderstorm
called a supercell.These storms are capable of producing their own wind
patterns in the atmosphere.
6)There are two major types of tornados:the wedge tornado
and the multiple vortex.The wedge can get to be a mile wide.But the multiple
vortex is the most deadliest.It can have anywhere from two to six additional
vorticies from the original tornado.For each vortex an additional 100mph
more wind is produced.
7) When trying to forcast tornados meteorologist look
for where the moisture in the air close to where the dry line is.And they
look for wind shear.the wind shear is what makes the winds in the upper
parts of the thunderstorm spiral therefore makeing updrafts and downdrafts.
Conclusion: :My hypothesis
was proven partially correct.
Questions raised for further study:
1) Why is the warning time so short for tornados?
2) Could the device used in twister really be used?
3) Do any ohter countries get as much severe weather
as we do?4)Do trailor parks really attract tornadoes?
