WaMoS Ⅱ测波雷达应用及对比分析

Comparative analysis on wave radar of WaMoS Ⅱ

利用大万山海洋环境监测站WaMoS Ⅱ雷达测量的数据与同步SZF遥测波浪浮标、SLC9-2型直读式海流计的数据分别进行了对比分析。结果表明WaMoS Ⅱ测波雷达获取的有效波高、波峰周期、表面流速、流向等海洋物理要素的变化趋势与SZF遥测波浪浮标获取的波浪数据及SLC9-2型直读式海流计测到的海流数据有较好的一致性。其中,2012年6月16—22日雷达和遥测波浪浮标对比结果为:波高、周期的相关系数分别为0.71,0.38,平均相对误差分别为23.3%,12.5%。6月28—29日的对比结果为:流速、流向的相关系数分别为0.83,0.89,平均相对误差分别为14.5%,4.1%。其中,WaMoS Ⅱ系统测量的有效波高值需通过对比分析进行校准,本文利用的对比分析数据时间序列较短,但经校准后,有效波高值的相关性仍可升至0.75。

This paper made comparative analysis of data from the WaMoS Ⅱ radar,synchronous SZF telemetering wave buoy and SLC9-2 direct-reading current meter at Dawanshan Marine Environmental Monitor Station.The result show that the trend of the significant wave height,wave period,surface current velocity and current direction from WaMoS Ⅱ radar have good consistency with the wave data from SZF telemetering wave buoy and the current data from the SLC9-2 direct-reading current meter.The correlation coefficient of wave height and wave periods are 0.71 and 0.38; and the APD of them are 23.3 ％ and 12.5 ％ between 16th June and 22nd June,2012.While from 28th to 29th,the result has shown that the correlation coefficient of the current velocity and direction are 0.83 and 0.89; and the APD of them are 14.5 ％ and 4.1％.And the significant wave height data of WaMoS Ⅱ could be corrected according to the comparative analysis.In this paper,the data for correcting is not enough but the correlation coefficient of significant wave height still reach to 0.75.
