The Norwegian Sea is the meeting place of warm and salty Atlantic waters with cold fresh Arctic waters. thermal haline frontal zones (FZs) formed as a result this interaction are areas increased horizontal gradients physical, chemical, biological parameters, have significant impact on regional circulation.

Strong rotation makes an underlying turbulent flow quasi-two-dimensional that leads to the upscale energy transfer. Recent numerical simulations show under certain conditions, is accumulated at largest scales of system, forming coherent vortex structures known as condensates. We analytically describe interaction a strong condensate with weak small-scale pulsations and obtain equation allows us ...

Abstract. A method for objectively extracting the displacement signals associated with coherent eddies from Lagrangian trajectories is presented, refined, and applied to a large dataset of 3770 surface drifters Gulf Mexico. The method, wavelet ridge analysis, general analysis modulated oscillations, here modified be more suitable eddy-detection problem. means formally assessing statistical sign...

We explore the Barreirinhas Eddies, submesoscale vortices generated by North Brazil Current (NBC) off Bight (Brazil, centered at 1.75°S), using vessel-mounted and moored ADCP data, a Global HYCOM reanalysis. These double-stacked anticyclones with incredibly high Rossby Number O (10)] occur independently different depths (high Burger number). Anticyclones number greater than unity are unstable a...

The mid-latitude atmosphere is dominated by westerly, nearly zonal flow. Occasionally, this flow is deflected poleward by blocking anticyclones that persist for 10 days or longer. Experiments in a rotating annulus used radial pumping to generate a zonal jet under the action of the Coriolis force. In the presence of two symmetric ridges at the bottom of the annulus, the resulting flows were near...
