| 中文摘要 | A three dimensional parabolic equation, including the current effect in both x and y axis, has been derived to investigate the effect of mesoscale eddies on acoustic propagation. The sound structure of a warm-core ring in the southwest of South China Sea is presented. Then propagation through the warm-core eddy is discussed. Further, the transmission loss for different cross angles has been examined. It is found that the influence of eddy on acoustic propagation decreases greatly with cross angle. In addition, the position of the eddy relative to the source causes changes in transmission loss of as much as 18dB. |
