Abstract: onostrophic instability leads to the spontaneous emergence of zonal jets on a ? plane from a jetless basic-state flow that is damped by bottom drag and driven by a random body force. Decomposing the barotropic vorticity ...

Abstract: he Reynolds stress induced by anisotropically forcing an unbounded Couette flow, with uniform shear ?, on a ? plane, is calculated in conjunction with the eddy diffusivity of a coevolving passive tracer. The flow is damped ...

Abstract: AbstractOceanic surface submesoscale currents are characterized by anisotropic fronts and filaments with widths from 100 m to a few kilometers; an O(1) Rossby number; and large magnitudes of lateral buoyancy and velocity ...

Abstract: AbstractThe distribution and strength of submesoscale (SM) surface layer fronts and filaments generated through mixed layer baroclinic energy conversion and submesoscale coherent vortices (SCVs) generated by topographic ...

Abstract: AbstractAn idealized framework of steady barotropic flow past an isolated seamount in a background of constant stratification (with frequency N) and rotation (with Coriolis parameter f) is used to examine the formation, ...

Abstract: We present in situ and remote observations of a Mississippi plume front in the Louisiana Bight. The plume propagated freely across the bight, rather than as a coastal current. The observed cross-front circulation pattern ...

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 ...
