- Tropical storm distribution - Where the storms occur
- Tropical storm intensity - How strong a tropical storm is.
- Formation
- 1. Sun sends solar radiation. warms sea to critical 27 degrees.
- 2. Warm moist air rises and gives low pressure at middle of storm.
- 3. Air cools as it rises causing condensation, cloud formation and rain. Some air sinks and creates the eye.
- 4. Air rushes from a high to low pressure, creating circling wind rotation.
- Coriolis - process by which warm air is spun.
- Wind categories
- 1. Dangerous winds, 119-153mph, bendy trees, roof tile damage
- 2. Extremely dangerous wind, 154-177mph, trees breaking, roof tile damage, weakened infrastructure
- 3. worse wind, 178-208mph, uprooted trees, broken windows, doors roof
- 4. Even worse winds, 209-251mph, trees gone, roof gone, walls gone
- 5. Even worse wind, 252+mph, Trees really gone, catastrophic damage

- 30 degree water and no land mass
- Secondary effects - business destroyed, looting, food supply damaged, illness
- Immediate responses - none in remote areas, RAF delivers aid within 10 days, supply boat, charities
- Primary effects - storm surge, 20ft floods, strong wind, lack of water and communication
