西北太平洋2017年秋季海浪、波浪能观测分析

Study on the wave and wave energy in the northwestern Pacific in autumn 2017 based on the observational data

针对西北太平洋浪场特点研究中现场观测数据的不足,本文利用海洋综合调查船的现场观测数据综合分析了混合浪、涌浪和风浪的变化特点,并计算波能的空间分布。结果表明:所观测海域的混合浪、涌浪和风浪的波高变化范围分别为0.7~5.7、0.3~5.7和0.6~4.1 m。周期和波能的变化范围分别为5.2~9.5 s和1.3~143.1 kW/m。ST0303站风速较小,混合浪浪高、浪向和波能均与涌浪具有较高的相关性,浪场特点主要取决于涌浪场。

Considering the insufficiency of observation data in the study of wave field characteristics in the northwestern Pacific Ocean,the variation characteristics of mixed waves,swells,and wind waves are comprehensively analyzed based on the observational data from a ship,and the spatial distribution of wave energy is also calculated.The results show that the ranges of wave heights of mixed waves,swells,and wind waves are 0.7~5.7 m,0.3~5.7 m,and 0.6~4.1 m,respectively.The ranges of the periods and wave energies are 5.2~9.5 s and 1.3~143.1 kW/m,respectively.The wind speed at the ST0303 station is small and the wave height,wave direction,and wave energy of the mixed wave are highly correlated with the swell.The characteristics of the wave field mainly depend on the swell field.
