摘　　要：根据1983～1989年南麂海洋站在台风影响过程中的实测风和浪资料，分析了该海域的波浪特征。结果表明，这个海域的台风波浪通常是混合浪，在台风影响过程中出现的最大值波高，既有较大波陡的风浪，也有波陡较小的清浪；各向波高的均值变化不大，各向最大波高却有较大幅度的差距；本区的台风浪以4级波高占优，风浪以NNE向、涌浪以E向为常浪向；波高为4级的风浪和涌浪，其周期分别在4．0～4．9S和7．0～7．9S之间时，它们的出现频率最高。Based on the data of winds and hurricane wayes at Nanji ocean station during 1983-1989, the characteristics of wave distribution in the area are analysed. The results show that the hurricane waves in the area are usually of the type of mixing waves. The largest wave height of hurricane waves may be the wave height of a wind wave, which has larger wave slopes, or the wave height of swell, which has smaller wave slopes. The mean value of the wave heights in all directions fluctuates within a narrow range. The extreme value of the wave height in all directions fluctuates within a large range. The occurrence frequency of the hurricane waves with force-four wave height is the highest in this area. The wind wave with the direction NNE and the swell with the direction E are most frequent in the area. The frequency peak of occurrence falls on wind waves and surging waves of force-four in height with periods of 4.0-4.9s and 7.0~7. 9s, respectively.
