海洋水文多参数测量仪确定主波向的方法和应用

A METHOD FOR DETERMINING DOMINANT WAVE DIRECTION BY USING MULTI-PARAMETER HYDROLOGICAL GAUGE AND ITS APPLICATION

海洋水文多参数测量仪是南海海洋研究所新研制的一种可以同步测量海流、波浪、潮位、水温、电导率的仪器,利用同步观测压力和矢量流速估计海面方向谱的方法(PUV方法)可以计算得到海面方向谱,进而求得主波向。利用该仪器现场实测数据与荷兰MARKⅡ型“波浪骑士”方向浮标观测资料进行对比分析,表明两者的主波向吻合性好。

Multi-parameter hydrological gauge is an instrument developed by the South China Sea Institute of Oceanology to measure synchronous current, wave, tide, water temperature and conductivity. By using the PUV method, a method to compute wave directional spectrum with observed pressure and current vectors, the wave directional spectrum can be calculated and the dominant wave direction is then obtained. The comparison of the dominant wave directions derived ＂Wave-Rider＂ directional from the multi-parameter hydrological gauge and the MARK Ⅱ buoy shows that both results coincide with each other well.
