- Tropical Stroms
- The 3 different types
- Cyclone- A system of winds rotating inwards towards an area of low pressure
- Hurricane- a violent tropical storm in the Caribbean region
- Typhoon- a violent tropical storm over the indian and pacific oceans
- How are these created?
- Fast-rising warm air creates an area of very low pressure - the eye- which sucks in air.
- The rotating winds cause low pressure close to the equator and absorb moisture from the oceans creating hurricanes, cyclones and typhoons.
- Fast-rising warm air creates an area of very low pressure - the eye- which sucks in air.
- What are the conditions for tropical storms?
- Ocean temperatures must exceed 27 and the water needs to be 60m deep
- Wind speeds are usually 74mph. Typically 700km in diameter and can exceed 13km in height
- What is a tropical storm?
- A large depression or cyclone that forms over tropical oceans and moves away from the equator.
- How do tropical storms affect people.
- When tropical reach land they cause 1.damage to buildings 2.Flooding caused by heavy rainfall.
- MEDC
- They have technology like weather satellites to monitor storms.
- Well-equipped infrastructure to deal with storms when they strike.
- LEDC
- People do not have the means to travel inland like people in MEDC's which have: emergency procedures, robust transport, resources and food supplies.

- When tropical reach land they cause 1.damage to buildings 2.Flooding caused by heavy rainfall.
- How can people be saved from the impacts of tropical storms?
- Disaster aid
- Set up relief camps to provide food, water and shelter in the immediate aftermath of a storm
- Promote individual responsibility
- Inform people on insurance
- Educate people so they know what to do if a storm happens.
- Offer low costing loans to help people strengthen their properties to make them more resistant.
- Hazard-resistant design
- Build embankments or levees around settlements so storm surges are less likely to flood areas.
- Strengthen houses and roofs so they are damaged during the high winds.
- Build houses on stilts so they are less likely to flood.
- Improve sanitation so there is less of a chance of sewage leaking into drinking water.
- Build better roads so that evacuation is easier and effective
- Strengthen and raise banks of rivers so increased precipitation will not lead to flooding.
- Build sea walls to protect densely populated areas.
- Warning and forecasting
- Improve weather stations to allow a more accurate warning of storms.
- Improve land use planning.
- Plant shelter belts of trees to along the coast that will shield homes from strong winds
- Zone land use so houses are not close to the coast
- Disaster aid
