Ingredients for a Hurricane
Hurricanes form in tropical regions with warm water and warm, moist air.
When tropical waters are heated to about 80F (27C) at the surface AND to a depth of 150 feet, a hurricane can form.
Hurricanes also need a cool atmosphere, a still ocean surface, and a distance of at least 300 miles from the equator.
Hurricanes can't just form anywhere...

How Do Hurricanes Form?
The very warm surface water evaporates and water vapor rises.
The water vapor condenses to form storm clouds and raindrops.
The condensation process releases a great deal of heat.
Water warming, evaporating, condensing, and releasing heat builds clouds and a core of low pressure.
7
Look closely at this storm...
Can you identify the eye of the storm?
In which direction is the hurricane spiraling?
8
Multiple Choice
Which way is this storm spinning?
9
The Movement of a Hurricane
Northern Hemisphere = counterclockwise
Southern Hemisphere = clockwise
Earth's rotation helps with the spinning of a storm and east-to-west winds help send the storm across the ocean
10
Parts of a Hurricane
The calm, low pressure center is called the "eye"
The area on the outside of the eye is the "eye wall"
"Feeder bands," or rain bands, are the outermost winds and rain.

FACT
Scientists estimate that the heat energy thrown off every 20 minutes by a single hurricane is equivalent to the energy released by the explosion of a 10-megatron nuclear bomb.
13
Storm Surge
As a hurricane strikes land (landfall) is pushes ahead of itself a hill of ocean water as high as 15 feet and 100 miles wide.
This hill of ocean water is called storm surge.
Rains worsen flooding near the shore.
