- Storm Hazards
- Huge spinning storms with strong winds and torrential rain
- Specific conditions needed to develop
- Area of low pressure
- Sea water must be above 27 degrees celsius
- so form in tropics as water is warm enough
- convergence of air in lower atmosphere, which forces warm air to rise
- Location at 5 degrees from the equator
- coriolis effect isn't strong enough to make them spin
- force that is caused by earths rotation which deflects path of winds but its weaker at the equator
- coriolis effect isn't strong enough to make them spin
- Lose strength as they travel over land as their supply of warm, moist air is cut off
- move westward, due to easterly wins in the tropics (trade wins)
- also move away from the equator
- characteristics
- hundreds of kilometres wide
- circular shape
- last 7-14 days
- low pressure at centre called the eye
- rising air spirals around the eye wall causes strong winds
- Saffir-simpson scale
- based on wind speeds
- estimates how much damage a storm of a given magnitude will do
- 5 categories, 1 is weakest and 5 is strongest
- satellite imagery
- certain cloud formations can be identified from this and are able to tell when a tropical storm is forming
- they can use this to work out when and where the storm is likely to hit land
- path of or tropical storm can be predicted
- they can use this to work out when and where the storm is likely to hit land
- certain cloud formations can be identified from this and are able to tell when a tropical storm is forming
