Hurricanes

Add labels to the diagram below. Include :- eye, eye wall, strongest winds, Storm Surge.

Cumulonimbus clouds, rotation of storm, Air drawn into the centre, Heavy rain.

Sort the statements below into where, when, what, why, consequences

Facts.

1.

Hurricanes start as tropical storms off the coast of West Africa

2.

Sea temperatures of 27C are needed

3.

Wind speeds get up to 300 km/h

4.

There is an eye around which the storm spins

5.

The eye is often fairly calm

6.

the eye wall has strongest wind speeds

7.

Warm moist air is drawn in from areas around

8.

The storm is often 600km across

9.

There is intense low pressure at the centre causing sea levels to rise

10.

The three hazards are torrential rain, strong winds and storm surges.

11.

Hurricanes get their energy from warm sea.

12.

Hurricanes die out on land

13.

in the Atlantic they form from August to November

14.

In the Pacific they are called Typhoons and in the Indian Ocean – Cyclones

15.

Hurricanes spin because of the rotation of the earth

16.

The best defence is a good weather forecast
