  1. Natural Disasters Hurricanes

  2. Hurricanes • Massive tropical storms • Occur over oceans near the equator

  3. Characteristics • Rotational winds • Circular motion • High-speed winds

  4. Characteristics • Energy 12X that of other storms • Eye • Area of low pressure • Clear skies • No rainfall

  5. Causes • Warm air forced upward by cooler air • Drop in atmospheric pressure and increased wind speed

  6. Prediction • 1943 US military aircraft • mid-1950 coordinated system • Currently • Radar, recording devices and satellite data

  7. Major Hurricanes • Fran 1996 (Florida) • Luis 1995 (East Coast) • Andrew 1992 (Gulf of Mexico)
