基于实测资料海洋内孤立波诊断模型设计

目的基于实测的海洋资料,研究设计海洋内孤立波诊断模型。方法首先对实测的ADCP海洋资料和温度链资料进行质量控制处理,然后利用海洋内波动力学理论和诊断分析技术,建立提取海洋内波特征的诊断模型。结果成功设计了能够提取海洋内波振幅、内波周期、变差流矢量时间序列、内波波致流和内波传播方向的诊断模型。结论该诊断模型通过实测的温度链、潜标、ADCP等连续观测的海洋资料,可诊断出海洋内波周期、内波振幅等特征要素,为实施海洋水文气象保障提供了重要技术手段。

Diagnosis Model Design of Internal Solitary Waves Based on In-situ Data

Objective To research and design a diagnosis model for oceanic internal solitary waves, based on the measured ocean data. Methods Firstly, the measured ADCP marine data and temperature data were processed, and then the diagnosis model of ocean internal wave feature was established by using the ocean internal wave dynamics theory and diagnosis technology. Results The diagnosis scheme was designed for extracting the amplitude, period, internal wave-induced flow and wave propagation direction. Conclusion The diagnosis model could diagnose the characteristic factor of ocean internal wave, such as period and amplitude, by using the measured temperature chain, submersible buoy and ADCP continuous observations of ocean data, which provided an important technical means for the implementation of marine hydrometeorological safeguards.
