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?

Global circulation

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

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

Characteristics

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
