Hurricane Attributes Causes of a Hurricane
Warm wet ______________ (intense low pressure) over the sea begins to ____ water and becomes stronger.
Hurricanes always have circulation ____________ in the Northern Hemisphere.
If the water is at __ degrees or above. Combined actions of air, water, and heat

Conditions Necessary First, the ocean waters must be warm
enough at the _________ to put enough ______ and _______ into the atmosphere
![Page 7: Hurricanes](https://reader035.vdocument.in/reader035/viewer/2022062814/56816727550346895ddbbdb9/html5/thumbnails/7.jpg)
Conditions Cont. Second, ________ from the evaporated
sea water must combine with the heat and ______ to form a source of fuel for the hurricane
![Page 8: Hurricanes](https://reader035.vdocument.in/reader035/viewer/2022062814/56816727550346895ddbbdb9/html5/thumbnails/8.jpg)
Conditions Cont. Third, a wind pattern must be near the _____________
This will allow the air to spiral ________
This process causes bands of ____________ to form, warming the air even further and causing it to rise higher in to the atmosphere
If winds at these higher levels are relatively light, the storm structure will remain intact, forming the basis for a hurricane

Tracking Hurricanes
![Page 19: Hurricanes](https://reader035.vdocument.in/reader035/viewer/2022062814/56816727550346895ddbbdb9/html5/thumbnails/19.jpg)
Tracking Hurricanes (Doppler Radar) Doppler ______ can detect rain associated
with tropical cyclones
It typically covers rain within a ___ to ___ mile distance from the location of the radar station
Doppler radar can also provide estimates of ________ amounts and help depicts a hurricane's rain bands, eye and eye wall.
![Page 20: Hurricanes](https://reader035.vdocument.in/reader035/viewer/2022062814/56816727550346895ddbbdb9/html5/thumbnails/20.jpg)
Tracking Hurricanes (Satellites) _________ allow meteorologists to look over several images of a
forming tropical storm
From here they can determine the symmetry of _____ patterns, and the character of the hurricane’s eye.
![Page 21: Hurricanes](https://reader035.vdocument.in/reader035/viewer/2022062814/56816727550346895ddbbdb9/html5/thumbnails/21.jpg)
Tracking Hurricanes (Reconnaissance Aircraft) During _____________, the Army Air Corps and Navy
pilots began making reconnaissance flights into the eye of hurricanes
The pilots gathered information on a hurricane's location and intensity
Today, reconnaissance aircraft are still actively used to gather tropical cyclone information
The information is then passed on to the National Hurricane Center (NHC) in Miami, Florida, and to _______________________________________.

WHY DO HURRICANES FOLLOW A CERTAIN PATH?
• Hurricanes that affect the US start out near the ________________ in Africa
• ____________ push hurricanes to the US• The eastward blowing ___________causes
hurricanes to approach the east coast• Areas in the US have their own fronts and
pressure zones which influence the hurricane

How Hurricanes Die When hurricanes
travel over ____ or ____ water, its energy source (warm water and moisture) is gone and the storm is weakened, causing it to lose its energy and die.

HURRICANE SAFETY
• Learn hurricane evacuation routes and follow authorities’ directions
• Secure your home and cover all windows
• Listen to ________ or radio for information
• Ensure a safe, plentiful supply of food and _____
• Take refuge in a small interior room on the lowest level
• Return out of cover only when officials say it is safe

Types of Hurricane Damage __________-An abnormal rise of water generated
by a storm. Caused primarily by strong winds of a hurricane. When the circulation of water reaches the continental shelf the water rises causing flooding and destruction of the coast.
__________-Very strong winds can blow down trees and remove roofs as well as create flying debris
__________- Flooding of major rivers and lakes add to the storm surge flooding as well as the torrential downpour from the Hurricane itself.
