Generation and Propagation of Internal Bores and Solitons in the South China Sea.
Abstract
The generation of internal bores and solitons by the interaction of the barotropic tide with sills in the Luzon Strait was studied with numerical models, along with their westward propagation across the South China Sea. The model domain extends from 116E-123E and 18N-23N, and includes the sills, gaps and islands of the Luzon Strait between Taiwan and the Philippines. Two classes of initial conditions were considered: (1) horizontally homogeneous density profiles representing an average over the domain, obtained from CTD's and/or climatology; (2) geostrophically balanced 3-D fields obtained from model solutions. Resolutions were typically 100m in the horizontal and 10-20 m in the vertical. The primary generation region was found to be the sill just south of Taiwan, and the sills between islands of the Batan Group in the Strait. The simulation results were compared with current meter records and CTD observations taken during the 2000-2001 ASIAEX experiments; these observations included both shallow and deep water locations.
