  1. TROPICAL STORMS AND HURRICANES Increased Storm Intensity due to Climate Change: Marques Miller Jordan Langworthy

  2. What is climate change? • Substantial increase in global temperatures over a long period of time. • Greenhouse effect. • Ocean circulation

  3. Climate Change Predictions

  4. Tropical Storms and Hurricanes • How are they formed? • Warm ocean water • Low pressure systems

  5. Considering factors when assessing storm intensity and occurrence Frequency Storm Surge Wind speed Inland effect

  6. Frequency Change in the number and percentage of hurricanes in categories 4 and 5 for the 15-year periods 1975–1989 and 1990–2004 for the different ocean basins. Period Basin 1975-1989 1990-2004 Number Percent Number Percent East Pacific 36 25 49 35 West Pacific 85 25 116 41 Northern Atlantic 16 20 25 25 Southwest Pacific 10 12 22 28 North Indian 1 8 7 25 South Indian 23 18 50 34

  7. Storm Surge • Definition • Effect • Factor of Influence • SLOSH http://www.nhc.noaa.gov/HAW2/english/surge/slosh4.gif

  8. Wind Speed • ACE Accumulated Cyclone Energy (ACE) =  • Damage

  9. Inland Effect • Inland cities • Topography • Flooding • Pressure release

  10. Is there a link? Heat energy theory of cyclone intensity One popular theory:

  11. Is there a link? *2003 case study • Attempted to find a link between tropical storm/hurricane intensity and sea surface temperatures. • Results were inconclusive when looking to find a linear relationship.

  12. Is there a link? • A report published in 2009 took a slightly different approach • Analyzed “potential intensity”

  13. Additional suspected effects of climate change • Melting of glaciers can cause the sea levels to rise • Warm air can hold more moisture possibly affecting rainfall

  14. Human Cost • Coastal Living • Money due to damage • Infrastructure effect • Prediction/Prevention
