内波存在的海洋温度场的构建

Construction of marine temperature field under the circumstance of internal waves

在内波发达的海区和季节里,内波是引起浅海声场起伏的主要原因之一。本文依据2010年青岛近海声学试验实测温度数据构建内波存在时的海洋温度场模型,利用实测温度数据分别获得恒温背景场、内潮波和内波,并对三部分进行叠加以获得内波环境下的海洋温度场。通过声模拟数据和实测数据的比对验证该海洋温度场模型的合理性。

Internal waves is one of the main reasons caused acoustic field fluctuation of shallow water in the sea area and seasons with developed internal waves. Based on the measured temperature data from the acoustic experiment in the shallow water of Qingdao in 2010, by obtaining and overlaying three parts of thermostatic ambient field, internal tides and internal waves respectively, this paper constructs the model of marine temperature field under the circumstance of internal waves. The rationality of the model of marine temperature field is verified by comparing the acoustic simulation data and measured data.
