Processes Coupling the Upper and Deep Ocean Over Topography: Towards Improving Model Initialization and Data Assimilation
نویسنده
چکیده
The specific scientific objectives of this project are focused on studying the dynamical coupling between meandering baroclinic jets with the deep flow over steep topography. Emphasis is placed on the initialization of baroclinic jets in numerical models and improving our understanding of the life cycle of energetic flow perturbations excited by meandering of baroclinic jets. The gained knowledge would allow us developing new model initialization and data assimilation techniques.

Our long term fundamental goals are 1) to develop a movable multiply nested mesh ocean model and investigate its application for air-sea interaction studies on the mesoscale, 2) to study coupled air-sea processes at very high wind speeds, 3) to investigate the capability of coupled tropical cyclone ocean models for improving predictions of the ocean response and tropical cyclone evolution, and ...
متن کاملEnhanced Predictions of Tides and Surges through Data Assimilation (TECHNICAL NOTE)
The regional waters in Singapore Strait are characterized by complex hydrodynamic phenomena as a result of the combined effect of three large water bodies viz. the South China Sea, the Andaman Sea, and the Java Sea. This leads to anomalies in water levels and generates residual currents. Numerical hydrodynamic models are generally used for predicting water levels in the ocean and seas. But thei...
متن کاملOcean Initialization for Seasonal Forecasts
The potential for climate predictability at seasonal time scales resides in information provided by the ocean initial conditions, in particular the upper thermal structure. Currently, several operational centres issue routine seasonal forecasts produced with coupled ocean-atmosphere models, requiring real-time knowledge of the state of the global ocean. Seasonal forecasting needs the calibratio...
