What is a Tornado?

• A tornado is a vortex of rapidly moving air, in
  an area.

3
How are Tornadoes Produced?

• Tornadoes are produced by differences in air
  pressure. When the high pressure and low pressure
  meet they can create fast moving air which can
  create a Tornado.

4
When and Where do Tornadoes occur in the U.S.A.?
Tornadoes occur mostly in the south and the
southeast. They occur during April, May, June,
July, and August
5
How are Tornadoes Classified?

• Tornadoes are classified by winds. The winds get
  to be at a high speed which makes it low
  pressure.

6
Why are Tornadoes Considered Severe Weather?

• Tornadoes are considered severe weather because
  the high winds on the outside of your house
  create low pressure while it creates low air
  pressure inside your house. Low pressure likes to
  go to high pressure which causes the roof to pop
  off because the low pressure is trying to get to
  the high pressure.
