What Are Typhoons?
A typhoon is a region-specific term given to a type of tropical cyclone, usually occurring within the northwestern region of the Pacific Ocean, west of the International Date Line. These same systems in other regions are referred to as either hurricanes, or more generally, tropical cyclones. The center of a cyclone is referred to as the eye. The eye is a circular area of calm, fair weather. On average, a tropical cyclone eye is about 30 miles across. Surrounding the eye are eyewalls which are regions of dense convective clouds. The winds of eyewalls are the highest and generally cause the most damage. Spiraling into the eyewalls are more convective cloud regions referred to as spiral bands. These areas contain heavy winds and extend out from the typhoon eye.
How Typhoons Form
Typhoons or hurricanes form in hot, humid conditions over the ocean when winds traveling in opposite directions meet, a phenomenon known as convergence. As the opposing winds collide, hot air is forced upward and cools to form storm clouds. Usually these storms produce nothing more than lightning or a period of heavy rain, but in some cases high pressure and wind in the upper atmosphere can allow the hot air to continue its upward motion for a sustained period, creating a much stronger type of storm. A hurricane's wind is caused by air rushing up from the surface of the ocean to replace air blown away in the upper atmosphere. Due to the Coriolis effect, which can affect the direction water drains down a sink, hurricanes in the northern hemisphere spin anti-clockwise, while in the southern hemisphere they spin clockwise.
