TRANSCRIPT
To be able to explain the characteristics and causes of hurricanes
What is latitude? Why is it relevant? What is longitude?
Why is this relevant?
Find a map of tropical storm distribution
• Describe the patterns • What language are we going to use?
Starter: Match the correct definition
Magnitude How often do hazards of similar magnitude occur?
Frequency How easily and accurately can the hazard event be predicted?
Duration How long does the hazard event last?
Areal extent The size of the event on a standard scale
Speed of onset What impact does the event have on people, environment, economy
Predictability The size of the area affected
Effects How quickly does the hazard reach its peak intensity?
Key terms
• High and low latitudes • Coriolis force • Trade winds• Rapid evaporation • Convection • Depression • Tropical disturbance • Ascending and descending air
Why do hurricanes form and what are their characteristics?

Now create your own guide to hurricane formation
• Use plasticine, photographs, videos or diagrams
• Take photos at each stage and annotate using the key terminology
Homework
• Create a map to show the typhoons, hurricanes and cyclones that have taken place in 2013.
• Identify the major cities affected by their latitude and longitude
• Read and make notes on this: http://www.bloomberg.com/news/2013-08-30/no-atlantic-hurricane-by-august-in-first-time-in-11-years.html
