- Tropical Storms
- A large area of low pressure that causes swirling masses of clouds, strong wind and rain
- They can be called hurricanes, cyclones, typhoons and willy-willies
- Begins on seas between the tropic of cancer and the tropic of capricorn
- It is close to the equator
- They tend to move towards the west due to the rotation of the earth
- Causes of Tropical Storms
- 1. The sea is at 27 degrees or more. This causes evaporation and warm water vapour rises from the sea
- 2. The water vapour cools as it rises into the atmosphere and turns back into water droplets, clouds are then formed.
- 3. When clouds can no longer hold the water it falls as rain (called precipitation)
- 4. The whole storm spins because of the earths radiation - this is called the cordis effect. The "eye" of the storm is created here.
- 5. Trade winds blow the storm along
- 6. The tropical storm can then blow on to the land and makes landfall. This is where it loses its energy.
