摘　　要：用在南海产生、发展的台风的风场资料和海浪资料,总结出处于不同发展阶段的南海台风影响下海面波浪的分布特征和预报关系式。在比较了南海台风与西北太平洋台风形成的波浪分布的差别后,探讨了造成这些差别的原因。最后,对所得的预报关系式作了验证,预报值与观测值比较符合。Based on wind and wave data in the typhoon area of South China Sea,the distribution model of wave height and period in different stages of typhoons which were formed in South China Sea is presented, with its forecasting relationship.It is found that: 1. In the typhoon formation stage, the waves are wind waves; 2. In the development stage, the waves are mixed with wind waves and swell. The wind waves propagated in the wind direction, and the path of the main wave (wave pocket) was in a spiral line, but the swell moved from the maximum wind area near the center and propagated towards the outside of the typhoon; 3. The distribution of wave height in the typhoons of South China Sea was different from those which moved on the Pacific Ocean. 4. when the typhoon moved faster. then the high waves tended more towards the right side of the typhoon.By using wave data of Waglan Island and the offshore area, the test results show that the calculated height of typhoon waves coincides basically with those measured.
