Numerical simulation study on inversion of two dimensional flow field using acoustic ray travel time

  • 摘要: 基于南海1998年夏季调查航次诊断计算的流函数场,选取越南以东偶极子发生海域,进行不同的声层析观测站位设置实验。模拟计算声线传播时间信息,然后应用基函数重建方法进行了流函数场的模拟反演研究,讨论了不同随机观测误差对反演结果的影响。研究结果表明该方法是可行的,在所选取的约833 km×833 km海域内,在观测海域外围配置19个声层析观测站位就能够很好地重构原流函数场,空间分辨率约为63.7 km,可以分辨模拟海域中尺度涡场结构,这是传统的基于海流计(CM)或声学多普勒剖面仪(ADCP)等观测方法所不能企及的。该观测技术和方法可以实际应用于近海大范围流场结构的遥感实时监测,为近海污染物等的扩散研究,海洋环境变化等提供实时观测流场资料。
