1. Bellwork 5/5
Today we are going to learn about Hurricanes. . . BUT, we are going to head into our final unit on Climate next week.
What are you curious to know about climate? What would you like to learn about?
COME UP WITH SOMETHING!!!

2. Hurricanes! Most violent storms on Earth To be called a hurricane
Wind speed in excess of 119 kilometers (74 miles) per hour
Rotary cyclonic circulation
Profile
Form between the latitudes of 5 degrees and 20 degrees
Known as:
Typhoons in the western Pacific
Cyclones in the Indian Ocean

3. Hurricane Names:
Named by ocean basin
A-Z
Male/Female

4. Anatomy of a Hurricane Eyewall Eye Wall of cumulonimbus clouds
Greatest wind speeds
Heaviest rainfall
Most dangerous part of the storm
Eye
At the very center
About 20 km (12.5 miles) diameter
Precipitation ceases
Winds subsides
Air gradually descends and heats by compression
Warmest part of the storm

6. Heat Engine
a device that produces motive power from heat, such as a gasoline engine or steam engine.

7. Hurricane Formation Form in all tropical waters except the
South Atlantic and
Eastern South Pacific
Energy comes from condensing water vapor
Develop most often in late summer when warm water temperatures provide energy and moisture
Most form as clusters of thunderstorms
Initial stage is not well understood
Tropical depression – winds do not exceed 61 kilometers (38 miles) per hour
Tropical storm – winds between 61 to 119 km (38 and 74 miles) per hour

9. Hurricane Decay Diminish in intensity whenever
They move over cooler ocean water
They move onto land
The large-scale flow aloft is unfavorable

10. Formation of a Hurricane
How is Global Circulation of Winds involved?
How does moisture in the atmosphere have an effect?
Why does a hurricane carry so much precipitation?
How does ocean surface temperature play a role?
How can ocean surface temperature change?
