Generation and Evolution of Mode-Two Internal Waves in Ocean
The objective of this study is to investigate the generation and evolution of mode-two internal waves on the shelf break. In this study, some historical mooring and satellite SAR data have been investigated for the detection of mode-two solitons in the ocean. A recent field experiment in May 2009 near Dong-Sha Island in the South China Sea (SCS) is first described and analyzed. During the experiment, a small mode-two wave has been observed following a huge mode-one soliton on the shelf. Then, the environmental conditions for the evolution of mode-two internal waves are assessed for parametric and sensitivity study. The generation of mode-two waves on the shelf by disintegration of mode-one solitons in the deep oceanis proposed and analyzed based on the theory of modal-decomposition. For comparison, the soliton characteristics of mode-one and –two waves from environmental parameters have been estimated. It ’s been shown that the soliton width of large mode-two waves is much sharper than mode-one waves.
