Abstract
The oceanic response to a typhoon on the continental shelf of the East China Sea is analyzed using the thermal structure and the velocity data observed by Autonomous Drifting Ocean Station (ADOS) drifters and a bottom moored Acoustic Doppler Current Profiler (ADCP). The typhoon resulted in a collapse of the seasonal thermocline and sea surface cooling due to strong vertical mixing and surface heat loss, and generated a strong near-inertial current and the near-inertial internal oscillation. The clockwise component in the inertial frequency was enhanced in the near surface layer and at 63 m depth during the 5 days after the typhoon passage. The clockwise components in these layers were almost out-of phase, which is characteristic of the near-inertial internal oscillation. The vertical shear current was intensified by interaction of the wind-driven current in upper layer and the background semi-diurnal tidal current during the typhoon arrival, and also by near-inertial internal oscillation after the typhoon passage. After the typhoon’s passage, strong current shear due to the near-inertial internal oscillation occurred and persisted over several days, even though there was no significant interfacial structure since the seasonal thermocline had collapsed.
