Where do Tropical Storms occur?
They occur 5° North or South of the equator over tropical oceans
kWhat do you need for a Tropical Storm to form?
- Sea surface temperature has to be over 27°C with a depth over 60m
- Very little wind shear
- Thunder storms
- Lots of moist air
How does a Tropical Storm or Hurricane form?
- Sun sends incoming solar radiation to earth which warms the ocean
- This warms ocean to 27°C
- This causes warm moist air to rise in thermals
- This gives low pressure at the centre of the storm
- This air cools as it rises at 1°C per 100m, this causes condensation to occur and clouds form. It rains.
- Cooled air sinks back down helping to create the eye
- Air rushes in from higher pressure area outside of the storm to lower pressure at the centre of the storm creating winds .
- The whole storm rotates because of the coriolis force
What is a primary impact?
Impacts during and straight after the event
What is a secondary impact?
Impacts long after the event
How does Climate Change affect tropical storms?
- More of the worlds oceans could be 27°C therefore more places could experience them
- Oceans will stay at 27°C for more of the year so number of storms per year could increase
- Higher temp means tropical storms will be stronger leading to more damage
