Typhoon

Typhoon is a severe, tempestuous tropical storm of northwestern Pacific Ocean. It has 75mile-per-hour winds which rotates around a calm central area, covering a huge surface. A typhoon has the same mechanical and climatological characteristics of a hurricane. The basin is demarcated within the Pacific Ocean from Asia, north of the equator, and west of the international date line. Although a typhoon may arise any time in the year, most storms tend to form between May and November.

Typhoon paths follow three general directions: 1) Straight; a general westward path affects the Philippines, southern China, Taiwan, and Vietnam. 2)Recurving; storms recurving affect eastern China, Taiwan, Korea, and Japan.
3) Northward; from point of origin, the storm follows a northerly direction, only affecting small islands.

Unlike hurricanes, typhoons are not named after people. Instead, they generally refer to animals, flowers, astrological signs, and a few personal names. However, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) retains its own naming list, which does consist of human names. Therefore, a typhoon can possibly have two names.
