亚帆赛间便携式高频地波雷达的海态观测

2010年汕尾亚运会帆船赛期间,便携式高频地波雷达OSMAR-S作为一种重要的海态监测手段在汕尾海域进行观测,为保障亚帆赛顺利举行提供海洋气象服务。雷达获取了汕尾海域近1个月连续的流速、流向、浪高、浪周期、风向和风速等数据,并与海监船搭载的海流计与测风仪以及现场布放浮标实测的数据进行了对比。对比结果表明:雷达与现场海洋仪器的观测数据较为吻合,初步验证了OSMAR-S探测近海海态特别是风浪参数的能力。

Sea states observation with a portable HFSWR during the 16th Asian Games Sailing Competition

As an important instrument for sea states monitoring,the portable high frequency surface wave radar(HFSWR) OSMAR-S was installed at the Honghai Bay of Shanwei,Guangdong Province to provide sea weather forecast services for the 16th Asian Games Sailing Competition in November,2010.The radar achieved continuous echo data and sea state parameters of the sea area for nearly 1 month,including current velocity,current direction,wave height,wave period,wind speed and wind direction.The radar-measured sea states are compared with the in-situ measurements by multiple instruments such as ship-borne current meter,anemometer and in-situ deployed buoys.The comparison results show good coincidence between measurements by radar and in-situ instruments,which preliminarily validates the capability of radar on monitoring coastal sea states,especially wind and wave.
