本文收集整理了2013—2014年朝鲜半岛周边的海浪观测数据,统计分析了该海域的波候(海浪气候态)特征,结果表明:(1)朝鲜半岛周边海域的海表风速、有效波高的峰值都出现在12月—翌年2月,有效波高在8月的次峰值比风速明显。(2)风向频率随季风变化明显,波向与风向没有很好的对应关系,其中,朝鲜海峡的波向在各个季节都以偏西南向为主。(3)朝鲜半岛周边海域在各个季节整体以3级浪为主,4级浪次之。(4)大部分海域的阵风系数常年在1.4左右。

The ocean environment should be considered in advance before the actions of marine search and rescue,disaster prevision and reduction,military and non-war military operations.Until now,there is on scientific research on the ocean environment of KoreanPeninsula in our country,which was presented in this study based on a hourly observation data from year 2013 to 2014of the surrounding waters of the KoreanPeninsula.The results show that,(1)the peak values of sea surface wind speed and significant wave height(SWH)appear from December to next year's February.There is also a comparative peak value of SWH in August.(2)The wind direction occurrence drifts with the monsoon obviously.The wave direction does not exhibit a good consistency with the wind direction.The high occurrence wave direction in the KoreanStrait is southwest all year round.(3)The high occurrence of SWH is class 3in each season in the surrounding waters of the Korean Peninsula,followed by class 4,except station 1(class 2all year round).(4)The high unite-occurrence of wave height and wave period in station 2is 4~6swave period and<1.0m SWH in autumn and winter,3~5swave period and<1.0mSWH in spring,4~6swave period and<1.0mSWH and>7swave period and<1.0mSWH in summer.station 7is 5swave period and 1.0m SWH in winter,4~5swave period and 0.5¹.0mSWH in spring,5~6swave period and 0.5¹.5m SWH and>8swave period and 1.0².5mSWH in summer,4~6swave period and 1.0¹.5mSWH in autumn.(5)The gust index in the research waters is 1.4all year round.From May to October,the gust index in station 1and station 2is larger than that in other stations,and the gust in station 2in December is high unusually.
