Parts of Hurricane 1. Exhaust Hot air drawn into the atmosphere. 2.  Storm Clouds Spiral in upper atmosphere. 3.  Eye Cool air descends into the 20-mile wide eye, a low pressure calm center of circulation. 4.  Eye Wall  Storm's fiercest winds.

Tracking of Hurricanes Methods used: Remote Sensing data Data collected from Hurricane Hunters Radars A radar image showing Charley Hurricane 2004

My approach using GIS I have used GIS to draw the tracks of Various Hurricanes. Acquiring Data: National Hurricane Center Data Used 1995-2002

Steps Involved Downloading the data into a Microsoft Excel Sheet Sorting the data to fit the GIS formats Getting the World Map

Importing the Excel sheets into GIS Creating a Shape file Creating a New Geo database Clipping the Part of World where Hurricanes Strike Extracting the US Cities struck between 1995-2002 Generating a Time Series Showing the Time series Variation Using Tracking Analyst

The Highlighted area shows the states that were struck by Hurricanes during 1995 - 2002
