Hurricanes are mind-boggling in their size and strength. Modern technology lets us see how big hurricanes are and track them through satellite imagery, while storm-penetrating aircraft measure their strength, in terms of wind speeds and atmospheric pressure. That technology gives us detailed warnings that people a century ago never had. Hurricanes usually form in the tropical zones north and south of the equator, where warm waters offer ample fuel for storm formation. That's where you see convection, where warm air rises and forms clusters of thunderstorms. The Coriolis effect, created by the Earth's spinning motion, may cause this cluster of storms to rotate (counter-clockwise above the equator, or clockwise below), but the system has to be a few hundred miles from the equator for the Coriolis force to exert an effect. If the system becomes organized and strong enough, with sustained winds of 39 miles per hour, it becomes a tropical storm. At 74 miles per hour or more, it becomes a hurricane. A hurricane can be hundreds of miles across. It's like a big engine, with upper-level winds acting as a vent, pulling the rising warm air away from the storm. Rain bands spiral around the center of the system. Air sinks in the clear center, or eye, which can be from 5 miles to more than 100 miles across. Because the atmospheric pressure is so low in the eye, the water rises up there in a sort of mound. This contributes to the devastating storm surge when a hurricane hits land, but most of the surge comes from winds pushing the sea water ahead of the storm, raising ocean levels by several feet. When a hurricane hits land, it tends to weaken mostly because it has lost its source of energy - the warm ocean waters. Friction might slow down the surface wind, but it also can enhance turbulence and therefore gusts, scientists have found. The Saffir-Simpson scale is used to classify hurricanes in the United States. It was invented by engineer Herbert Saffir and former National Hurricane Center director Robert Simpson. Here's a summary:

Warm water heats the air causing it to rise really quickly, then it gets pushed aside as it cools. This pushing causes the clouds to spin. When does it become a hurricane? Hurricanes are tropical storms where the winds get faster than 118 km/h (73 mph). The storms have a central area of calm known as the "eye", which is the funnel through which the warm air rises. Overland, the storms no longer have warm water to power them and die out within a few days, but not before winds do a lot of damage. Hurricanes generally last for about two to four weeks. It is rare to have a hurricane last longer, because they are eventually going to hit land or cold water, where they cannot survive. The only hurricane known to last in the Arctic for more than a day is Hurricane Erin, 2001. Hurricanes form when warm, wet air masses over the Atlantic Ocean heat up, expand, and rise up into the sky. Underneath the mass, a rush of wind suddenly appears to form a 'donut' shaped 'cloud'.

How are cyclones formed? Cyclones are formed when moist, hot air rises Water condenses out of it, and convection begins. If this convection develops a circulation, it can create a cyclone. This event usually happens in the doldrums. The Coriolis, which causes circulation makes tropical cyclones rarely, form close to the equator. Areas with cold waters do not see tropical cyclones, because this prevents formation. Tropical Cyclones derive their energy from the warm tropical oceans and do not form unless the sea-surface temperature is above 26.5�C, although, once formed, they can persist over lower sea-surface temperatures. Tropical cyclones can continue for many days and may follow quite unpredictable paths.

Hurricanes form when warm, wet air masses over the Atlantic Ocean heat up, expand, and rise up into the sky. Underneath the mass, a rush of wind suddenly appears to form a 'donut' shaped 'cloud'. Hurricanes last for about 9-12 days.

How do hurricanes form? Hurricanes begin as clusters of thunderstorms (tropical disturbances) over the warm waters of the Atlantic, Carribean and Gulf of Mexico. As development continues, they develop into Tropical Depressions, then Tropical Storms (at this point, the storm is named), and finally, hurricanes. Hurricanes are categorized on the Saffir-Simpson Scale, ranging from a category 1 (weakest) to a category 5 (strongest).

Hurricanes are formed by 3 steps. First, the oceans must be warm enough to give the hurricane moisture. Second, Atmospheric moisture from the oceans must combine with the heat and energy to make the engine needed to propel the hurricane. Third, you have to find it out your self.

Hurricanes form mostly during the warmer months of the year. During warm weather the sun heats the oceans surface all day long. Some of the water changes into a mist called water vapor. The warm water vapor rises high into the air as it does this cooler air ruches into replace it. This cause winds to form.

In meteorology, the study of motion and atmospheric phenomena of the atmosphere a cyclone is the rotation of a volume of air with low atmospheric pressure, which causes high winds in the area. Cyclones also cause a variety of other disasters such as hurricanes and typhoons.

A Cyclone begins when a warm, wet mass of air over the sea begins to rise quickly. Then combined actions of air, water and heat may then produce a huge, spinning system of clouds, rain and wind- a cyclone. The center, or eye, of a cyclone�is calm. It is a hole in a dough-nut of wind. It forms and builds strength over warm sea water of at least 26.5�c. It loses energy as it moves over cooler sea water or land. Here is a better picture.

1.winds going in opposite directions meet over the sea where heat from the sun evaporate huge amounts of water. 2.The warm air rises and more air rushes in to take it place. It goes around and up in a spiral. 3.Gradually the winds blow faster and faster until it reaches anything between 118KPH and 320 KPH. 4. The hurricane moves westward and it is usually about 300km across.
