Temporal variability of diapycnal mixing over 7 months in the northern South China Sea was examined based on McLane Moored Profiler observations from 850 to 2200 m by employing a finescale parameterization. Intensified diffusivity exceeding the order of 10−3 m2/s in magnitude was found over the first half of October 2014, and from 2 December 2014 to 21 January 2015 (a typical wintertime). Strong internal tides and winds in winter were the likely candidates for the high‐level diapycnal mixing in winter. As for the enhanced mixing during October 2014, we suspect the generation of near‐bottom near‐inertial waves through the interaction of mesoscale eddies and unique bottom topography was the cause.
