摘要

　　The relation between track of typhoons and the height of waves against the coast is studied by solving equations numerically. Coastal waves caused by typhoons crossing the Bashi Channel has been taken as an example.
　　Waves produced by a typhoon moving in the direction of W, WNW, or NW and passing the area 55-165 km south of Kentin are higher than by a typhoon in other situation. Along the coast of Kentin, the waves produced by a typhoon moving in the direction of NW are higher than those produced by a typhoon in the direction of NNW and W. When the advancing speed of a typhoon is high (30km/hr), or low (10km/hr), the wave heights will decreases.
