Large rises in sea level caused by low pressure and high winds of a storm.

How can tropical storms be predicted?
Scientists use data from equipment such as radar, satellites and aircraft to track storms. Computer models are used to calculate a predicted path for the storm.

What are the advantages of predicting a storm?
Gives people time to evacuate, reducing injuries and death. Also gives time to protect homes and business by boarding up windows

What are some secondary impacts How do building techniques reduce the impact of tropical storms?
Using reinforced concrete, fixing roofs securely, put buildings on stilts so they are safe from floodwater, flood defences such as sea walls and levees

What can governments do to reduce the impact of a tropical storm?
Educate people about how to prepare e.g. told how to make a survival kit, including water, food and medication. Told how to evacuate

What are the primary effects of tropical storm?
Buildings and bridges destroyed, flooding, people injured or killed, roads, railways, ports and airports damaged, electricity and telephone cables damaged, crops and livestock lost, erosion

Why is it difficult to define a drought?
Because the length of a drought can differ globally. E.g. A drought in the UK can signify 16 months without average rainfall, but in the Sahel region in Africa it could signify a decade!

Describe 2 causes of droughts.
Changes in atmospheric circulation means there might not be as much rain. High pressure system which prevents a depression moving into the area.

What are ways you can reduce the impacts of drought in an MEDC?
Don’t water the lawn, don’t wash the car, don’t fill a new pool, don’t wash hard surfaces.
9 of 12
What are some secondary impacts of droughts?
People and animals die from dehydration/famine. Farms close causing unemployment. Wildfires
10 of 12
Why in the Sahel Region did the drought turn into a full blown famine, yet in the UK we have simply introduced a hose pipe ban?
Different levels of development, access to alternative water and food sources, length of drought.
11 of 12
What type of climatic zones are prone to drought?
Areas of high and very high aridity. Generally found near the equator or between 30o N and S.
