发布时间：2018-08-31 07:50
【摘要】：为了更好地掌握我国台湾岛周边的海浪特征,利用来自台湾岛的海浪观测数据,采用气候统计方法,分析该海域的波候(海浪气候态)特征,主要包括波高和波浪平均周期的季节特征、强浪向、大浪频率、阵风系数。结果表明:台湾岛周边的有效波高(SWH)在冬季最大,秋季次之,夏季最低,台东近海的SWH、平均周期常年大于台湾海峡;台湾周边的强浪向常年以偏北向为主,夏季的最大波高为全年最大,冬春两季偏低,冬季台湾海峡的最大波高大于台东近海,春、夏、秋季则相反;东沙岛、台东外洋的大浪频率明显高于其余站点,马祖、澎湖次之,其余站点整体较低;花莲和龙洞各代表月的阵风系数为1.4~1.5,鹅銮鼻常年在1.3左右,澎湖为1.2~1.4。
[Abstract]:In order to better understand the characteristics of the waves around Taiwan Island in China, using the observation data of the waves from the island of Taiwan and using the method of climate statistics, the characteristics of wave climate (wave climate state) in the sea area are analyzed. It mainly includes the seasonal characteristics of wave height and wave mean period, strong wave direction, wave frequency and gust coefficient. The results show that the effective wave height (SWH) around Taiwan Island is the largest in winter, followed by autumn, and the lowest in summer. The average period of SWH, in the coastal waters of Taitung is longer than that in the Taiwan Strait, and the strong wave direction around Taiwan is northward. The maximum wave height in summer is the largest in the whole year and is lower in winter and spring. The maximum wave height in the Taiwan Strait in winter is higher than that in the coastal waters of Taitung, but in spring, summer and autumn, the frequency of large waves in Dongsha Island and the outer ocean of Taitung is obviously higher than that of the other stations, Matsu. The gust coefficient of each representative month in Hualien and Longdong was 1.4? 1. 5. The annual wind coefficient of Luanbi was about 1. 3, and that of Penghu was 1. 2 and 1. 4.
