- How can the effects of tropical storms be reduced?
- Prediction
- Weather data is fed into supercomputers which run models.
- These models predict the path and intensity of tropical storms.
- Supercomputers can give five days' warning
- A more accurate location within 400 kilometres
- The National Hurricane Centre in Florida predicts the storms path and intensity
- for up to seven days using a 'track cone'
- The cone shape allows for error with the unpredictable behaviour of tropical storms.
- Especially when it hit lands.
- Around 70 per cent of tropical storms occur within the predicted cone.
- The cone shape allows for error with the unpredictable behaviour of tropical storms.
- for up to seven days using a 'track cone'
- National Hurricane Centres issue early warnings
- This is so people have time to prepare to evacuate.
- Some may not bother.
- Evacuation is costly and time-consuming, particularly if the path of the tropical storm doesn't pass the area.
- This is so people have time to prepare to evacuate.
- Weather data is fed into supercomputers which run models.
- Planning
- American National Hurricane PreparednessWeek in May
- Aims to encourage people to plan what they need to have and do in the event of a tropical storm
- Preparing disaster supply kits
- Having fuel in vehicles
- Knowing where official evacuation shelters are
- Storing loose objects
- Planning with family what to do

- Monitoring
- Satellites
- There is a classic cloud pattern associated with tropical storms that satellites monitor.
- It was discovered that rainclouds that reach approx. 16km in altitude are more likely to indicated that a tropical storm will intensify within 24 hours,
- The Global Precipitation Measurement satellite was launched in 2004.
- It monitors precipitation every three hours.
- Between latitudes 65 degrees north and south of the Equator to identify high altitude rainclouds.
- Aircraft
- A plane first flew purposely into a hurricane in 1943
- To make observations
- Now specially equipped aircraft frequently fly into tropical storms
- At 10,000 feet to collect air pressure, rainfall and wind speed data.
- They release sensors which send measurements every second by radio back to the aircraft.
- A plane first flew purposely into a hurricane in 1943
- NASA measures weather patterns across the Atlantic
- Using two unmanned aircraft called Global Hawk drones
- With on-board radar and microwaves to help scientists understand more about the formation of tropical storms.

- Protection
- Buildings have areas of weakness that can be reinforced to reduce damage by forces winds of tropical storms
- Mitigation
- Install hurricane straps (galvanised metal) between the roof and walls.
- Install storm shutters on windows
- Install an emergency generator
- Tie down windburn objects e.g. garden furniture
- Reinforce garage doors
- Remove trees close to buildings
