1. IMPORTANT TERMS AND DEFINITIONS:
  • Hurricane: A low pressure system that has thunderstorm activity, wind speeds greater than 74 mph, and rotates (Also known as a tropical cyclone.) Only tropical cyclones that form over the Atlantic or eastern Pacific Oceans are called "hurricanes".
  • Tropical Storm: A low pressure system with winds lower than a hurricane (less than 74 mph).
  • Spiral Rainbands: Bands of heavy clouds. Rain (and winds) extends out to the extent of the spiral rainbands.
  • Eye: The center of a hurricane.
  • Safir-Simpson Hurricane Scale: A scale used to define hurricane strengths by categories. The weakest category storm is a Category 1 (winds range from 74 - 95 mph); the strongest category is a Category 5 (winds are greater than 155mph)
  • Knots (kt): A unit of speed used in meteorology. 1 knot (kt) is equal to 1.151 mph. (Source: Wikipedia)

2. EARTH SYSTEM INFORMATION:
Hurricanes are associated with the atmosphere. They gain strength through interactions with the hydrosphere. As the move over warm water, they can gain strength. As a hurricane moves over land, it affects the land (geosphere), often causing coastal erosion. This can also lead to serious concerns related to the biosphere (loss of human life, destruction of corals, loss of seagrass, etc.).

Hurricane Characteristics: The criteria for identifying a hurricane are:
1) A center of circulation (an eye)
2) Spiral rainbands
3) Wind speeds of at least 74 mph

Hurricane Eye Characteristics: The criteria for identifying the eye of a hurricane:
1) Located at the center of the hurricane
2) Somewhat circular in shape
3) Can be open or closed








5. ASTRONAUT IMAGES (2-3) THAT INCLUDE THE FEATURE YOU ARE STUDYING (links, ID#s, or images):

6. GEOGRAPHIC REGION OF FOCUS:
Will probably focus on hurricanes in the Atlantic or Pacific oceans.

7. IF YOU WILL CONDUCT A PLANETARY COMPARISON, PLEASE EXPLAIN:
This research will focus only on Earth.

8. OTHER DETAILS IMPORTANT FOR YOUR RESEARCH:
Will need to look at another source to find the strength of a storm on a specific date. Can use the National Weather Service National Hurricane Center Data Archive. Website: http://www.nhc.noaa.gov/pastall.shtml
