Abstract: The authors develop and test computational methods for advection of a scalar field that also include a minimal dissipation of its variance in order to preclude the formation of false extrema. Both of these properties are ...

Abstract: Dissipation in numerical ocean models has two purposes: to simulate processes in which the friction is physically relevant and to prevent numerical instability by suppressing accumulation of energy in the smallest resolved ...

Abstract: Density stratification and planetary rotation distinguish three-dimensional island wakes significantly from a classical fluid dynamical flow around an obstacle. A numerical model is used to study the formation and evolution ...

Abstract: The K-profile parameterization scheme is used to investigate the stratified Ekman layer in a ?fair weather? regime of weak mean surface heating, persistently stable density stratification, diurnal solar cycle, and broadband ...

Abstract: submesoscale filament of dense water in the oceanic surface layer can undergo frontogenesis with a secondary circulation that has a surface horizontal convergence and downwelling in its center. This occurs either because ...

Abstract: AbstractFour numerical simulations are used to characterize the impact of submesoscale circulations on surface Lagrangian statistics in the northern Gulf of Mexico over 2 months, February and August, representative of ...

Abstract: n this study, uncoupled and coupled ocean?atmosphere simulations are carried out for the California Upwelling System to assess the dynamic ocean?atmosphere interactions, namely, the ocean surface current feedback to the ...

Abstract: AbstractThis paper, the second of three, investigates submesoscale dynamics in the northern Gulf of Mexico under the influence of the Mississippi?Atchafalaya River system, using numerical simulations at 500-m horizontal ...
