What is a Hurricane and how do they form?

Hurricanes need the following conditions: They need an ocean temperature of more than 27°c. The warm-water depths of 70 metres. It also needs high levels of heat causing violent updrafts of air. High levels of humidity. Major winds blowing in the same direction. These are the vital conditions that a hurricane needs. This is how a hurricane forms. Large thunderstorms drift over warm water. The warm air from the storm combines with the ocean surface and then they begin to rise. This creates low pressure at the surface. Trade winds blowing in the opposite direction cause the storm to start spinning. Rising warm air causes pressure to decrease at higher altitudes. Air rises faster and faster to fill this pressure then drawing warm air off the sea and sucking cooler drier air downwards. As the storm moves over the ocean it picks up warm moist air. Wind speeds start to increase as more air is sucked into the low pressure centre. It can take hours of several days for a depression to grow into a fully- formed hurricane. Hurricanes are made up of an eye of calm winds and low pressure surrounded by a vortex of high winds and heavy rainstorms. When a hurricane hits land it often has devastating effects.
