摘要

Abstract

During the observational period of our study

Typhoon Hagupit passed over the mooring site and induced strong near-inertial waves (NIWs)

which provided an opportunity to investigate the interactions between internal tides (ITs) and NIWs. Based on the mooring data

we compared the current spectra during the typhoon period and non-typhoon period in the northern South China Sea

and found that the high-frequency waves (fD1 and fD2) were evident during the former. Moreover

the observations of the current revealed that fD1 and fD2 occurred near the depth of strong vertical shear in the NIWs. In order to confirm the generation mechanism of fD1 and fD2

we compared the positions of strong vertical shear in the NIWs and strong vertical velocity in the ITs. It was established that the vertical shear of the horizontal current of the NIWs and the vertical current of the ITs contributed to the generation of fD1 and fD2.
