Influence of Remote Internal Tides on the Locally Generated Internal Tides upon the Continental Slope in the South China Sea

In this paper, the M<sub>2</sub> internal tides (ITs) originating from the continental slope in the South China Sea are studied using the CROCO model. The simulation results show that there are two origins of ITs on the continental slope: at 118°–119.5° E along 22° N near the southern en...
