摘要/Abstract

摘要：

利用海南东方近岸海域2014年至2015年间一整年的海浪观测资料, 分析了海浪的时间变化特征。观测时间段内, 有效波高最大值为4.03m, 平均值0.79m; 平均周期最大值为6.32s, 平均值为3.58s。该海域冬季波高较大, 秋季最小, 常浪向为SSW方向, 强浪向为WSW向。基于该长期观测数据, 文章亦研究了平均周期、有效波高之间的关系, 同时还确立了该海域波高与平均持续时间之间的关系。最后讨论了观测时间段内波浪能流密度的变化特征, 发现一年中能流密度大于2kW·m^-1的频率为26%, 且从全年的计算结果来看, 观测位置处12月的波浪能较适宜开发, 但总体波浪能资源不够丰富。文章对于认识海南东方近岸海域波浪特征以及工程设计都具有重要的意义。

Abstract:

Temporal variation characteristics of ocean waves in the coastal area of Dongfang, Hainan are analyzed based on observations of ocean waves for a whole year from Aug 1, 2014 to Jul 31, 2015. During the observation period, the maximum height of the significant wave height was 4.03m, the average was 0.79m; the maximum value of the mean period was 6.32s, and the average was 3.58 seconds. In this sea area, the wave height was higher in winter, with minimum in autumn. The normal wave direction was SSW, and the strong wave direction was WSW. Based on the one-year observation data, the relation between the mean period and significant wave height was studied, and the relation between the significant wave height and its mean duration was also established. Finally, the variation characteristics of wave energy density in the observation period were discussed. We found that the frequency of wave energy density above 2kW·m^-1 in one year was 26%, and the wave energy at the observation location increased faster in December, but the total wave energy resources were not rich enough. The results obtained in this study are of great significance for understanding the wave characteristics and engineering design of the coastal area of Dongfang, Hainan.
