Hurricanes are tropical cyclones. They are like giant engines that use warm , moist air as fuel. That is why they form only over warm ocean waters near the equator.
How a Hurricane is Formed
A hurricane is made of bands of thunderstorms that spiral around the centre. The surrounding clouds may have a diametre of 300 miles and reach a height of six miles. In order for a hurricane to form a layer of warm sea water must be at least 27 ℃ and 60 metres deep. Wind must be converging near the surface. As air rises, more air flows into replace it, causing wind. The water vapour in rising air condenses into droplets, releasing latent heat, the latent heat warms the surrounding air which makes the air become lighter, so it rises. the winds, at all altitudes must be the same speed and direction. In high pressure areas in the upper atmosphere pumps away air rising in the storm. When all these factors happen, a hurricane is created.
The safest place in a hurricane is the eye and the most dangerous part is the eye-wall.
