| 摘 要： | 针对海洋初始温度场误差到水声传播误差的传递以及随时间演变发展的问题,优化海洋-声学耦合模式,通过对比遥感数据,验证了模型的可靠性。在此基础上,采用在控制试验温度初始场上加扰动的方法进行传播损失全局误差发展和区域误差发展试验。结果表明,初始温度场全局扰动在经过5天繁殖后使传播损失误差达到饱和,且扰动分布结构和海洋运动规律基本保持一致;对于在黑潮流域设定的目标海区,其上游区域的初始扰动发展最快。该结论可为开展海洋声学适应性观测提供依据。

| Abstract: | Focusing on transfer and evolvement of initial perturbation from temperature of ocean to the underwater acoustic propagation,optimizing Ocean-Acoustic coupled model,comparing with remote sensing data,the reliability of the model is verified.On this basis,global and regional error development experiments are carried out by adding perturbation on the initial temperature of a controlled test.The results show that after 5 days evolution of the initial temperature field,the global perturbation of the propagation loss is satured,and the perturbation structure is basically consistent with the law of the dynamic ocean;for the target area in Kuroshio region,the initial perturbation in the upstream region is the fastest.This conclusion can provide the basis for the adaptive observation of ocean acoustics. |
