Introduction In 2005, the hurricane season in the Atlantic was the most dynamic season, so much so that it surpassed preceding records in history. The impact of these storms left over 3,000 deaths and record damages of approximately 130 billion (US) dollars. The First Storm formed on June 8th of 2005, and the last storm ended January 6, 2006
Tropical Storm – TS
Categories – 1,2,3,4,5
Tropical Depression - TD

Controversy
The Effect of Sea Surface Temperature on the strength of Hurricanes has been very controversial for some time. Many theories and atmospheric models all predicted a stronger hurricane at higher Sea Surface temperature. However, field observations of sea surface temperature and wind speed yielded inconclusive or contradicting results.

Using Resources
Using the NASA Website (http://Poet.jpl.NASA.gov) we were able to insert specific data from each hurricane

Take the data of the highest wind speed, then the distance, temperature, longitude, and latitude (which was sorted from the smallest to largest) and place them in a separate excel document. Next, you create the graph, wind speed being the y axis, and sea surface temperature being the x axis. This is done for every hurricane of 2005. Placing all of the final data together from each storm, will accumulate the final correlations analyze.

Based on the Final Correlation graph, Higher wind speed only occurs in higher temperatures. In areas with lower temperature, high wind speed doe not occur. Thus supporting the belief that sea surface temperature is not a primary factor in hurricane formation.
