莺歌海洋站附近海域波浪特征分析

Analysis of Wave Characteristics in the Sea Area Near the Yinggehai Station

本文利用莺歌海站多年的波浪实测资料,对其附近海域的波浪要素的基本特征、变化规律、风与浪的相关规律进行分析研究,阐明了海区海浪的特点及变化规律。该海区属热带季风气候区,波浪主要受季风影响,季风时期的风向、风浪传播方向、涌浪传播方向基本一致。通过对观测资料统计分析发现:该海域波浪主要是以风浪为主,常浪向是SE向,次浪向是SSE向,强浪向是SE向,波高以轻浪为主。波型方面,春季和夏季SE向风浪占绝对优势,秋季和冬季NNW向风浪占优势,涌浪频率四季均是S向最大,并结合国内海洋波浪测量技术现状,在仪器装备研发、算法模型及数据处理分析软件升级、站位布局优化、计量标准化研究等方面提出几点建议。

Based on the measured wave data of Yinggehai station for many years,this paper analyzes and studies the basic characteristics of wave elements,variation rules and the correlation between wind and wave in the sea area near Yinggehai ocean station,and clarifies the characteristics and variation rules of waves in the sea area.The sea area belongs to the tropical monsoon climate zone,the waves are mainly affected by the monsoon,and the wind direction,wave propagation direction and swell propagation direction are basically the same in the monsoon period.Through the statistical analysis of the observed data,it is found that the waves in the sea area are mainly wind waves,dominated wave direction is SE direction,the secondary wave direction is SSE direction,the strong wave direction is SE direction,and the wave height is mainly light wave.In combination with the current status of domestic ocean wave measurement technology,the research and development of instrument equipment,algorithm models and Several suggestions were put forward in terms of data processing and analysis software upgrade,station layout optimization,and measurement standardization research.
