浅海内波与声场起伏

SOUND FLUCTUATIONS AND INTERNAL WAVES IN SHALLOW WATER

    摘要
  • 摘要: 本文对存在于尖锐负跃层浅海中的内波,及其引起的声场起伏进行了初步的实验研究,在3.6公里上测得的声场振幅起伏与内波活动有明显的关联性,但其统计特性不完全一致,所测内波温度谱接近于ω-3而振幅起伏谱接近于ω-2,对引起振幅起伏之机制我们倾向于Desaubies的看法。

     

    Abstract: In this paper the results of an experiment concerning internal wave and sound fluctuation in shallow water are presented. A very sharp thermocline occurs in August in the shallow water region of the Yellow sea near China coast, the temperature difference Δt is about 10℃ and the thickness of transition layer is only a fewmeters.
