TORNADOES
By: Stacy Walterbusch and Rob King

2. Tornado Formation From anvil clouds or thunderheads
Occurs during electrical storm
Strong current of warm air must be present

3. (continued) Severe Thunderstorms Most common in Tornado Alley
From any time of the year…but most form in May

4. Step 1 of Formation
Wind and speed change causing spinning effect

5. Step 2 of Formation
Rising air moves the spinning air from horizontal to vertical

6. Final Step of Formation
An area of rotation, 2-6 miles wide, now extends through much of the storm.

7. Tornado Spin Patterns
The Earth's spin causes the wind to curve. This is called the Coriolis Effect
Spin cyclonically or anticyclonically
Low and high pressure circulations are reversed in opposite hemispheres

8. Where Tornados Occur Majority in Agricultural Areas
Need moisture to grow

9. What Tornados Can Do Tremendous destruction Wind speeds up to 250 mph
Damage paths can be in excess of one mile wide and 50 miles long.
