Presentation transcript:

Describe the conditions needed for a thunderstorm to form. Bell Ringer Describe the conditions needed for a thunderstorm to form. Warm, moist air, uplift, instability

Hurricanes Whirling tropical cyclones (low pressure system) producing winds of at least 119 km per hour (73 mph) US – Hurricanes Pacific – Typhoons Indian Ocean – Cyclones Most powerful storm on Earth

Occurrence and Development of Hurricanes Form between 5 and 20 degrees north and south latitude Season: June 1 to November 30th Development of Hurricanes Hurricane develop most often in the late summer when water temperatures are warm enough to provide the necessary heat and moisture to the air Low Pressure: Spins counterclockwise

Parts of a Hurricane Video Eye: Center of storm, warmest part, winds cease, rain ceases Eye wall: Strongest winds and rain Spiral Rain Bands: extend out from the eye wall

Hurricane Intensity Storm Surge: is a dome of water that sweep across the coast causes by the hurricane’s winds Caterized on the Saffir-Simpson Scale (based on wind speed) What is Storm Surge Video

Hurricane Warning and Watches Hurricane Watch: could see hurricane related hazards within 48 hours Hurricane Warning: Could see hurricane winds within 36 hours

Create a chart/thinking map comparing and contrasting tornadoes and hurricanes. You should include: Location Associated storms Pressure associated with the storm Impact on society Maximum wind strength
