摘要

LONG-TERM GOALS: The goal of this work is to better understand the generation, propagation, modal transformations and interaction of multiple Nonlinear Internal Waves (NLIWs) on the continental slope and shelf using nonhydrostatic models embedded in nested hydrostatic models with realistic forcing and bathymetry. Accuracy will be assessed by hindcasting and forecasting the temperature, salinity and velocity fields for the SCS (South China Sea) north and east of Dongsha island and comparing the results with data from the experiments of this DRI and from the ASIAEX experiment. This work will provide the understanding needed to build an operational system to predict the timing, location and intensity of NLIWs as required for tactical planning. OBJECTIVES: * To identify the mechanisms responsible for the generation, propagation, fission, interaction and modal transformations of NLIWs on the slope and the plateau north and east of Dongsha Island in the SCS. * To hindcast these NLIWs using high resolution nonhydrostatic and hydrostatic numerical models with realistic ocean topography and surface forcing and using open boundary conditions provided by the large scale ocean model. * To determine the space and time scales involved in these processes that influence NLIWs on the continental shelf and slope of the SCS and their relationship to local and remote forcing.
