摘要
基于Argo资料,利用一种新的海洋声场季节特征分析方法,对127°E—130°E、20°N—22°N区域内声速一年的时间变化特征进行了定性的分析,按其相似性特点进行归类,分析它们形成的原因。利用MATLAB软件对其声场传播进行了仿真,并讨论各种结构对作战的影响。通过分析可知,Argo数据能够提供中小尺度海洋声场的时间变化特征,主要结果如下:1)此海区声速垂直分布类型的时间变化与上层混合强度、太阳辐射有关;2)声速垂直分布的时间变化趋势可分为6个阶段。
Based on Argo data,a new way to analyze character of sound speed was brought forward.By this way,the sound speed time sequence of a small area of 127°E-130°E、20°N-22°N was qualitatively analyzed and classified by the comparability,then put a interpretation on the events.Then,simulate the sound field and analyze the relationship to military by MATLAB.The main results are as follows:(1)Argo data can offer a small scale of character of time sequence of sound speed;(2)The time sequence of the vertical distribut...
