Remote sensing observation and numerical simulation of oceanic internal waves around the Bali Island: A preliminary study on the possible causes of an Indonesian submarine wreck

  • 摘要: 基于巴厘岛北部海域海洋内波卫星遥感观测与数值模拟结果,本文对4·21印尼潜艇失踪事件原因进行了初步分析。结果表明,在印尼潜艇失事海域和时间,源于龙目海峡的海洋内波向北传播并广泛分布于巴厘岛北部海域,振幅可达50 m。潜艇很可能遭遇了大振幅海洋内波发生“掉深”而导致失事。

    Fig.  2  Propagation of the internal waves from the LOMBOK strait simulated by the ray tracing method. The background color indicates the distribution of the maximum depth-integrated body force for the M2 constituent. The blue and red lines represent the leading wave front observed from the MODIS image acquired on April 19, 2021 and April 21, respectively. The black lines represent the simulated wave fronts in one-hour time step. The black solid dot marks the location where the sunken submarine was discovered
