Abstract:

The long term goal of this project is to develop a better understanding of oceanic processes in the range of 100 m to 10 km, in the so-called sub-meso-scale range. In particular, it is important to explore and find out whether and what type of sub-meso-scale instabilities exist, how they are connected to both larger scale and smaller scale motions, and to what extent they influence transport processes in the ocean. Another important objective of this project is to test how well subgrid-scale SGS models for large eddy simulations LES work in the presence of backward energy cascade that may be characteristic in sub-meso-scale motions. Another long term objective of this effort would be how to improve the predictive skill of the Navy numerical models in the light of the impact of sub-meso-scale motions in the ocean.
