Energy and Information Fluxes at Upper Ocean Density Fronts

We present large eddy simulations of a midlatitude open ocean front using modified state-of-the-art computational fluid dynamics code. investigate the energy and information fluxes at submesoscale/small-scale range in absence any atmospheric forcing. find submesoscale conditions (Ro∼1, Ri∼1) near surface within baroclinic structures, related to partially imbalanced frontogenetic activity. Near surface, show significant scale coupling on scales larger than ∼103 (m). This is manifested as strong direct cascade intense mutual communication between scales, where latter evaluated an estimator based Mutual Information Theory. At smaller (m), results near-zero flux; however, this range, still shows values corresponding with level them. fact motivates investigation into nature self-organized turbulent motion weak energetic but inquire existence synchronization or functional relationships emphasis eventual underlying nonlocal processes.
