Hurricane

The term hurricane is used for a tropical cyclone (tornado) in Atlantic, especially in the Caribbean Sea.. Hurricanes evolve when several strong storms burst out upon the ocean. There is a warm air, which goes up from the sea level. That makes low pressure upon the sea level. As the storm is moving upon the ocean, it takes more and more warm and vapourish air. Then it can last several days until the hurricane is formed. If the hurricane comes to the land, it makes a lot of damage. The power of hurricane is scaned by the Saffira and Simspon degree scale. The first degree of hurricane means the rate of the wind from 88 to 152 kilometres per hour and it causes slight floods, little damages on the land, and waves reach about 125 centimetres. But the last degree (fifth) means the rate of wind more than 248 kilometres per hour and the hurricane causes big damages of houses, floods intervening to inland, and waves reach to 6 metres upon standard sea level.
