Hurricanes homework
1.
What causes a tropical cyclone or hurricane? Where does a hurricane get its energy?
-It forms over warm ocean waters near the equator. The release of latent heat can be the primary energy source for hurricane.
2.
What are the 2 main locations where hurricanes that strike eastern North America tend to originate
?
-Atlantic ocean and Caribbean sea
3.
Where in a hurricane is the atmospheric pressure the lowest, and approximately how low is the pressure for a category 3 storm?
-
The lowest pressure is at the center of the storm, which is the eye. The central pressure is in the range of 945 to 964 mb.
4.
What 4 factors do studies suggest can be used to help predict the number of North Atlantic hurricanes that will occur in a given year?
-
Sea Surface Temperatures, Atmospheric Wind Patterns,
Atmospheric Pressure Patterns, Atlantic Multidecadal Oscillation
5.
What is storm surge? As a hurricane moves onto land, where is the storm surge largest and why?
- Storm surge is a rapid rise in sea level that occurs during a hurricane. It is largest on the right side of the storm's eye in the Northern Hemisphere, because of the combined effect of the hurricane's forward motion and counterclockwise rotation.
