摘要：

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.
