what causes tornadoes
by: Hannah Williams
why did I choose this topic and how does it relate to me personally?
I choose this topic because I have always been interested in tornadoes and I hate them at the same time so I want to know more about them.
how does this topic relate to everyday life and why is it important?
tornadoes happen all over the world and have been happening very often lately.
fact #1
The intense spinning of a tornado is partly the result of the updrafts and downdrafts in the thunderstorm (caused by the unstable air) interacting with the wind shear, resulting in a tilting of the wind shear to form an upright tornado vortex.“Storm Aware." Storm Aware. N.p., n.d. Web. 26 May 2015
fact #2
Tornadoes are unusually warm and humid conditions in the lower atmosphere, and possibly cooler than usual conditions in the upper atmosphere. Generally, warm air rises, but when the two fronts meet, the cold air can trap the warm air beneath it.

fact #3
Because the warm air cannot move upward, it begins to rotate. As the sun heats the ground, more warm air continues to rise, until finally the mass is strong enough to push through the cold air barrier.
fact #4
The rising warm air pushes the cold air beneath it, creating a rotating column that can span up to 10 miles, while twisting at speeds exceeding 200 miles an hour.

fact #6
Damage paths can be in excess of one mile wide and 50 miles long
fact #7
Before a tornado hits, the wind may die down and the air may become very still. A cloud of debris can mark the location of a tornado even if a funnel is not visible. Tornadoes generally occur near the trailing edge of a thunderstorm.
