This is caused by the tidal diffusion asymmetry in which the vertical turbulence diffusion in the ebb tides is weaker than the one in the floodtides.
动力分析表明这是由潮扩散的不对称性造成的,即落潮期间垂向湍流扩散比涨潮期间弱。

The basic pattern during floodtides is for oceanic water to flow north into Mirs Bay, west through Victoria Harbourand north through Kap Shui Mun and the Ma Wan Channel.
潮涨时的基本模式是海水向北流入大鹏湾,西经维多利亚港,北通汲水门及马湾海峡。

So unless the sub just happens to find itself close to a familiar shoreline, where it is unlikely to survive the floodtides and sloshing of the shift, they will be lost.
