Geography
Year 9 Geography Exam Revision Pack
When is the exam? 1st February
What will you be examined on?
WILD WEATHER: 1) Tropical storms 2) Floods 3) Droughts
1) Tropical storms / Hurricanes / Typhoons / Cyclone (all the same event)
The strongest tropical storms are called hurricanes, typhoons or tropical cyclones. The different names all mean the same thing, but are used in different parts of the world. If these huge storms start in the Atlantic, off the west coast of Africa, they are called hurricanes.

In an average year, over a dozen hurricanes form over the Atlantic Ocean and head westwards towards the Caribbean, the east coast of Central America and the southern USA (Florida in particular). Hurricanes may last as long as a month and although they travel very slowly - usually at about 24 km/h (15 mph) - wind speeds can reach over 120 mk/h (75 mph).
Effects of tropical storms
The intense winds of tropical storms can destroy whole communities, buildings and communication networks. As well as their own destructive energy, the winds generate abnormally high waves and tidal surges. Sometimes the most destructive elements of a storm are the subsequent high seas and flooding.
MEDCs are better placed to reduce the effects of tropical storms because they have more financial, educational and technological resources to help deal with them. They better able to observe and predict storm behaviour and can invest in infrastructure to withstand storms - as well as spending more money on repairing the damage caused.
Preparation and prediction
Preparation and prediction techniques to help cope with hurricanes can be very different in MEDCs and LEDCs.
MEDCs
MEDCs have the resources and technology, such as satellites and specially equipped aircraft, to predict and monitor the occurrence of storms. They are also equipped to train the emergency services appropriately and to educate people about necessary
