The Behaviors of Internal Solitary Waves near the Continental Shelf of South China Sea Inferred from Satellite Images
The behaviors of internal solitary waves (ISWs) near the continental shelf of SCS are analyzed. We interpret manifestations of four kinds of ISWs in MODIS images: mode-1 depression wave, bolus, mode-1 elevation wave, and mode-2 convex wave. The geographical distributions of these ISWs are investigated. Bolus and mode-1 elevation wave, the two evolution stages of polarity conversion process of depression ISW, only exists around 22˚N, which is in agreement with the sign of mode-1 nonlinear coefficient α1. The mode-2 convex waves generally follow the southern part of mode-1 depression ISW, where the steep terrain favors their generation. The information of a mode-1 depression ISW, such as amplitude and propagation speed, is also derived from the MODIS image.
