Nonhydrostatic and Hydrostatic Hindcasts and Simulations of Internal Wave Generation in Straits

摘要

The purpose of this study is to understand the feasibility of forecasting the dynamics of the generation and life cycle of large amplitude internal waves and their impact on the larger scale flow. The forecasting system may include imbedded nonhydrostatic models, subgrid scale models or subgrid scale parameterizations in hydrostatic models. The scope of the dynamics and the resolution which can be included in a forecast system will be explored. 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. To investigate the generation, development, propagation and interaction of IWs and NLIWs in straits using nonhydrostatic and hydrostatic models. 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.
