  1. Hurricane Tracks A Closer Look GIS in Water Resources By Veerender Garg Fall 2004

  2. Parts of Hurricane • 1.ExhaustHot air drawn into the atmosphere. • 2.  Storm CloudsSpiral in upper atmosphere. • 3.  EyeCool air descends into the 20-mile wide eye, a low pressure calm center of circulation. • 4.Eye Wall Storm's fiercest winds. Many agree that the most deadly area of a hurricane is the eye wall. • 5.Spiraling WindsIn the hurricane's lower realms, air flows in toward the center and whirls upward.

  3. What Causes a Hurricanes • How long do Hurricanes last? • How are Hurricanes named?

  4. Classification of Hurricanes: • Category One Hurricane: • Wind Speed 74-95 mph (64-82 kt or 119-153 km/hr) • Category Two Hurricane: • Wind Speed 96-110 mph (83-95 kt or 154-177 km/hr) • Category Three Hurricane: • Wind Speed 111-130 mph (96-113 kt or 178-209 km/hr) • Category Four Hurricane: • Wind Speed 131-155 mph (114-135 kt or 210-249 km/hr) • Category Five Hurricane: • Wind Speed greater than 155 mph (135 kt or 249 km/hr)

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

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

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

  8. 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

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

  10. A map showing the Track of Hurricane Allison

  11. Conclusions • Possibilities of an area being hit by Hurricanes • Is there a Particular Trend

  12. Places where Hurricanes struck more often within USA between 1995 - 2002 A table showing the States where Hurricanes have struck mostly in USA between 1995 - 2002

  13. Some fields where such Information be used • Investments • By Finance companies • Building purposes • Deciding the Economy

  14. Questions …… Suggestion……. Thank You!
