  1. Storms and Disasters Have any been in the news recently?

  2. Weather Disasters • http://p6atkingspark.weebly.com/the-beaufort-scale-photos.html

  3. The Beaufort Scale • Force 0 = Calm, wind less than 1km/h, water like a mirror. • Force 2 = Light breeze, winds 6 - 11 km/h, water rippled into wavelets. • Force 3-4 = Gentle to moderate breeze, winds 12 - 28 km/h, flags blow about. • Force 5 = Fresh breeze, winds 29 - 38 km/h, moderate waves, many whitecaps. • Force 7 = Moderate gale, winds 50 - 61 km/h, sea heaps up, white foam blown about. • Force 9 = Strong gale, winds 75 - 88 km/h, slight damage to trees and buildings. • Force 10 = Whole gale, winds 89 - 102 km/h, severe damage to trees and buildings. • Force 11 = Storm winds, 103 - 117 km/h, widespread damage. • Force 12 = Hurricane, winds over 117 km/h, devastation. http://www.metacafe.com/watch/1068104/storm_with_force_10_by_beaufort_scale_in_atlantic_ocean/

  4. Your Task… • Use a blank piece of paper to illustrate a number from the Beaufort Scale. • Remember to use the whole page! • Include: • Force Number • Speed • Effect on sea and land • Title of force e.g. “hurricane”, “light breeze”
