How does the eye of a hurricane change as the strength of a hurricane increases?

2. HYPOTHESIS (Include a brief explanation of observations & other knowledge that support this hypothesis):
Based on the observations we have made of hurricanes that have come through our area and the observations we have made of astronaut images of hurricanes, we hypothesize that the stronger the hurricane, the more defined the eye will be. The more defined the eye is, we believe this will cause the eye to be more circular. We also believe stronger hurricanes will have "open" eyes. We believe this because we compare water going down a drain to hurricane. The stronger the water is draining, the more visible and open the center area.

The data we will collect from each image is as follows:
1) Image Identification #
2) Hurricane name
3) Wind Speed (knots)
4) Wind Speed (mph)
5) Storm Strength/Category (TS (Tropical Storm) = <74 mph; Hurricane Categories:1= 74-95mph; 2= 96-110mph; 3= 111-129mph; 4= 130-156 mph; 5= 157+ mph)
6) Hurricane location
7) Date of image
8)"Eye" State: Open or closed
9) "Eye" Shape: Circular, irregular
10) "Eye" Definition: Well defined, somewhat defined, or not well defined
11) Miscellaneous notes or observations
12) Sketches of Hurricane "eye"
13) Student(s) logging data [we included this so that we would know who collected the data if we had any questions about the info.]

(NOTE: The data to be collected as part of this research was revised/updated from the initial plan. This was due to the type of information found when searching for historical hurricane information on the NOAA website ( Always be prepared to make refinements and adjustments to your data collection based on data available. As adjustments are made, all team members should be sure to make those changes. This will help team members collect consistent data.)

Here is a blank data table (an excel spreadsheet) that will be used to log data.

We will need to use other information, other than astronaut images, to find the wind speed in knots, the wind speed in miles per hour (mph) and to determine the hurricane location of each hurricane in each astronaut image. We will gather this data from the NOAA website: This site includes detailed information on all hurricanes.

We will not make any measurements as part of our research.
