A typhoon is a tropical storm occurring especially in the region of the Philippines or the China Sea. It is basically a cyclone originating from the Northwestern Pacific Ocean. The storm’s areas of activities expand from the north of equator to the west of International Date Line. Reportedly, these basins receive the strongest cyclones. Though typhoons are not limited to any particular season of the year, they form mostly between May and November.
Usually a typhoon is accompanied by heavy rainfalls and can generate a heavy wind up to 290 kilometers per hour. Its coverage area can expand up to 800 kilometers. Every year Japan receives significant damage from such tropical storms. The rainfall caused by a typhoon can lead to severe landslides and devastating tides.
Typhoons normally move along a looping track. These courses were identified by analyzing the path records of typhoons formed between 1980 and 2005. There are three most common paths of typhoons. The straight path is the westward path of typhoons across the Philippines, Taiwan, Southern China and Vietnam. The recurving path of typhoons is the most devastating, inflicting damage more than any other path. It lies across China, Korea, Taiwan and Vietnam. Typhoons sometimes follow a northward path from their origin, but only affect some small islands along the path.

Hurricane and Typhoon
The terms “typhoon” and “hurricane” are two different names for the same type of tropical system “cyclone.” These storms have a mass of air that spirals around a low pressure center more than 74 mph. If they form in the Western hemisphere (North Atlantic), then they are called hurricanes while in the Eastern hemisphere, they are given the name typhoon (Northwest Pacific Ocean). These tropical disturbances are accompanied by rain, thunder and lightning.
In the Northern Pacific, almost 90 percent of the typhoons originate from the Federated States of Micronesia (FSM), also known as “Chuuk” (formerly Truk). The sea in that area is comparatively shallow, which makes perfect condition for the birth of typhoons. According to Saffir-Simpson scale, a typhoon sometimes can turn into a super-typhoon, when it crosses the wind speed of 300 kilometers per hour.
A typhoon is formed when warm air and cold air collide together and then rotate in counter-clockwise direction. They spin until the wind gets strong enough to form the typhoon. The eye of a typhoon has clear skies and light winds. But outside the eye, strong winds spiral around and these storms often bringing heavy precipitation. A typhoon can persist as long as two weeks or even more over an open sea.
