1. Aim: How are Hurricanes different from large storms?
Do Now: Answer the following question in your notebook, what doe the rotation of this storm tell you about the pressure within the center?

2. Hurricanes (tropical storms)
Large, low pressure systems (cyclones)
develop in the later summer and early fall.

3. II. Development
Begin to form 5 and 20 degrees north and south of the Equator.
fueled by warm tropical waters which add a lot of moisture into the air.

4. Hurricanes have a very predictable life cycle which is categorized by wind speeds.
Tropical Disturbance
Tropical Depression
Tropical Storm
Hurricane
*Only until the wind speed reaches 74 mph is the storm considered a hurricane

5. III. Structure
air sinks in the center called the eye, which is clear because of this sinking air.
spiral bands of rain clouds extend out form the center.

6. IV. Movement counterclockwise rotation (low pressure)
they move west between 00 and 300N.
their rotation carries them north above 300 .
above 300N, they are carried by prevailing winds up the east coast of North America.

8. V. Damage and Destruction
storm surge is created by waves piling up on the coastline.
intensity of hurricanes are measured using the Saffir-Simpson scale which categorizes hurricanes as 1-5 based on wind speed, storm surge and damage caused.
