【摘要】：利用两台高频地波雷达(ground wave radar,WERA)站对山东半岛北部雷达覆盖海区的浪、流场进行了观测,并且利用海洋-大气-波浪耦合沉积输运模型(coupled-ocean-atmosphere-wave-sediment transport modeling system,COAWST)对该区域的一个强风暴过程进行了数值模拟,对雷达观测数据、现场声学多普勒流速剖面仪(acoustic Doppler current profilers,ADCP)调查数据和数值模拟结果进行比对分析发现,模型模拟的水位变化与ADCP测量结果一致,WERA所观测到的有效波高和ADCP结果比较吻合,模型模拟的ADCP站位的流速相位、大小与雷达观测结果比较接近,与ADCP的结果有一定偏差。雷达观测的海区流场结果与模型反映趋势基本一致,但是在近岸方向上变化较大,其原因可能与ADCP的投放位置、模型的分辨率设置等因素有关。高频地波雷达系统是海岸带动力环境观测的一个有效工具,在实际应用中有着广泛的前景。
[Abstract]:Two high frequency ground wave radar (ground wave Radar WERA) stations were used to observe the waves and current fields in the radar covered sea area of the northern Shandong Peninsula. A strong storm process in the region is simulated by using the coupled-ocean-atmosphere-wave-sediment transport modeling system coupled wave transport model (COAWST), and the radar observation data are analyzed. The results of field acoustic Doppler velocity profiler (acoustic Doppler current) were compared with the results of numerical simulation. It was found that the simulated water level of the model was consistent with the measured data of ADCP. The effective wave height observed by WERA was in good agreement with that of ADCP. The velocity phase and magnitude of the ADCP station simulated by the model are close to the radar observation results, and deviate from the results of ADCP. The results of the current field observed by radar are basically consistent with the trend of the model, but there is a great change in the inshore direction. The reasons may be related to the location of ADCP and the resolution of the model. High frequency ground wave radar system is an effective tool for coastal dynamic environment observation and has a wide prospect in practical application.
