The paths of Typhoon
The chart shows three most frequent tendencies of tropical cyclones movement over Northwestern Pacific.
Most tropical cyclones form on the side of the subtropical ridge closer to the equator, then move poleward past the ridge axis before recurving north and northeast into the main belt of the Westerlies. When the subtropical ridge position shifts (due to El Niño), so will the preferred tropical cyclone tracks. Areas west of Japan and Korea tend to experience much fewer September–November tropical cyclone impacts during El Niño and neutral years. During El Niño years, the break in the subtropical ridge tends to lie near 130°E which would favor the Japanese archipelago. During La Niña years, the formation of tropical cyclones, along with the subtropical ridge position, shifts westward across the Western Pacific Ocean, which increases the landfall threat to China. Those that form near the Marshall Islands find their way to Jeju Island, Korea. Typhoon paths follow three general directions：
• Westward track. A general westward path affects the Philippines, Southern China, Taiwan, and Vietnam.
• Parabolic track. Storms recurving affect Eastern China, Taiwan, Korea, and Japan.
• Northwestward track. Storm follows a northwesterly direction, only affecting Taiwan and Eastern China.
