摘要
印度洋北岸的波浪来自于几千公里以外的风浪传播变化,波向集中、周期长、强度大。实测波浪进行统计时波周期经常呈现混合浪的特征,季节性变化比较大,雨季周期长、旱季周期短。根据2010年2月～2011年12月在印尼爪哇岛南岸中部的实测波浪资料,对波浪谱进行分析研究。通过对各月份内逐日的波浪过程进行能量谱分析,得出印尼面向印度洋的爪哇岛南岸存在2种波浪结合的双峰谱特征,雨季低频涌浪能量大,旱季低频涌浪和高频波浪能量相当。
The wave of the north shore of the Indian Ocean is generated by the wind wave propagation from thousands of miles away,with the characteristics of concentrated wind direction,long wave period and high intensity . When the wave was measured,the period characteristic of mixed wave often occurred,including large seasonal variation,long rainy season period and short dry season period. According to the measured wave data during February 2010 to December 2011 in the middle of southern bank of the Indonesian island of Java,the wave spectrum was analyzed. On the daily analysis of wave energy spectrum in each month,the spectrum characteristic was obtained that 2 kinds of wave were combined into double-peaked wave at the south bank of the island of Java. The low frequency surge takes more energy in the rainy season,while the low frequency surge and high frequency wave take almost equal amount of energy.
