摘要To study the behaviors of near-inertial waves and the physical mechanism of nonlinear interaction between near-inertial waves and diurnal internal tidal waves by employing the data collected by moored ADCP in the northwestern South China Sea, the authors analyzed kinetic energy spectra, rotary spectra and the spectra of horizontal component difference in vertical direction. The authors investigated the upper-ocean responses after Typhoon Neoguri in the South China Sea (SCS) in April, 2008, and found that the intense energy of near-inertial waves after Typhoon Neoguri was dominant in the upper 250 m,which is about 40 times of the average value of near-inertial waves induced by winds (excluding Typhoon Neoguri). The energy of near-inertial waves can propagate downward to similar to 450 m. Furthermore, the intense horizontal flow difference drives interaction between near-inertial waves and diurnal internal tidal waves, and (f+D-i) were oberserved. The wave-wave couple mechanism provides observational evidence for theoretical results. The process of nonlinear interacting reveals a significant energy dissipation mechanism in SCS.
