HideShow resource information
How hurricanes form (1)
Hurricanes need a lot of heat to form, which is why they usually occur over tropical seas (at least 26°C).
1 of 9
How hurricanes form (2)
The sun is close to the equator, providing energy to heat the ocean.
2 of 9
How hurricanes form (3)
The warm ocean heats the air above it causing it to rise rapidly.
3 of 9
How hurricanes form (4)
Water evaporates quickly from the hot surface of the ocean, so the rising air contains great amounts of water vapour.
4 of 9
How hurricanes form (5)
The rising air starts to spin (clockwise in the northern hemisphere)

As the air rises it cools, condenses and forms towering cumulonimbus clouds.

The rapidly rising air creates an area of intense low pressure. The low pressure sucks in air, causing very strong winds.
