Hurricanes are among good number destructive forces on earth. Thanks to Hurricane Katrina, we've all seen the break they can cause. Do you know how hurricanes approach about and why they occur so often in the tropics?

The earth, since we all know, rotates approximately the sun and its axis is tilted toward the sun. These factors are main fundamentals of tropical weather. The tropics get together a lot of heat, which must be dissipated. A tropical storm is how this heat is dissipated to nearby latitudes.

Hurricanes, typhoons and tropical cyclone are the most influential tropical storms. (They are called hurricanes east of the International Date Line, typhoons west of that line and tropical cyclone in the Indian Ocean and approximately Australia. They form when large cloud areas form into thunderstorms by convection and evaporation. If these storms are about 10 degrees or additional from the equator, they can be deflect by the Carioles Effect caused by the earth's rotation. This deflection causes the storm to turn, rising its power. As the storm moves away from the equator, it continues spinning faster and winds increase. If wind speed reaches 39 mph, it is classified as a tropical storm. If it reaches 74 mph, it is a hurricane, typhoon or tropical cyclone, depending on the location as listed above.

Because of the spinning natural world of a tropical storm, the center of the storm, call the eye, has very low pressure. Thus situation there are peaceful, the temperature is colder and the sky is clear. However, the strongest wind and heaviest rain are established at the eye wall, the area right away surrounding the eye. Thus the eye wall can cause the majority damage to property.

Since the eye wall is so powerful, meteorologists learn them carefully. Stronger storms might have eye ramparts that form a total circle, while weaker ones only have partially formed walls. Occasionally, the external rings of the storm will block moisture from reaching the wall, thus failing its momentum. As this happens, the storm may weaken but a new eye and eye wall may emerge additional out from the center. When this happens the storm get stronger.

The group of tropical storms is hard to predict, which is my meteorologists path them so closely. While they can path when high winds will arrive at an area, they cannot always predict when a tempest will reach land. Storms weaken as they travel over ground.
