针对位于东海外缘台湾东北部冲绳海槽张裂带以西的深海海域声速场的统计资料,分析利用少于5号经验正交函数描述声速场,探索利用经验正交函数、海表和温跃层水温对海水声速剖面进行预报的方法.研究结果对于声速场数据库的建设、海洋声速场的预报和水下声层析技术具有重要的意义.
According to the statistical data of the sonic velocity field in the deep sea west of the Okinawa Trough in the northeastern part of the Taiwan Strait on the outer edge of the East China Sea, this paper analyzes the acoustic velocity field by using the empirical orthogonal function of less than 5, and explores the use of the empirical orthogonal function, Layer water temperature on the sea sound velocity profile.The research results are of great significance for the construction of the sound speed field database, the prediction of ocean sound velocity field and underwater acoustic tomography.
