We rely on the f-plane approximation to derive nonlinear governing equations for arctic wind-drift flow in regions that are not vicinity of North Pole. An exact solution is derived material (Lagrangian) framework, a setting suitable accurate description particle paths. This approach facilitates identification oscillations superimposed mean spiralling Ekman current.

Abstract The prediction of ocean currents is essential for the path planning and control Autonomous Underwater Vehicles. Regional physics-based forecast models provide valid predictions but are too computationally expensive real-time necessary AUV navigation. While vehicle sensors can measure spatial evolution currents, temporal remains an open problem as existing data-driven with capabilities ...

Abstract Oceanic tides lead to some of the largest currents world ocean and have important implications for oceanic circulation. In last decade, feedback effect surface on overlying winds has been shown strongly regulate Here we present evidence, using coupled high-resolution ocean-atmosphere simulations in situ measurements, that can drag atmosphere above. The current-induced tidal expand acro...

Signatures of eddy variability and vorticity forcing are diagnosed in the atmosphere and ocean from weather center reanalysis and altimetric data broadly covering the same period, 1992–2002. In the atmosphere, there are localized regions of eddy variability referred to as storm tracks. At the entrance of the storm track the eddies grow, providing a downgradient heat flux and accelerating the me...

Recent studies predict that the Arctic Ocean will have ice-free summers within the next 30 years. This poses a significant challenge for the marine organisms associated with the Arctic sea ice, such as marine mammals and, not least, the ice-associated crustaceans generally considered to spend their entire life on the underside of the Arctic sea ice. Based upon unique samples collected within th...

A cloud-resolving model coupled to an ocean model with high vertical resolution is used to investigate air– sea interactions in 10-day long simulations. Modeled fields showed good agreement with two different convective regimes during the Tropical Ocean Global Atmosphere Coupled Ocean–Atmosphere Research Experiment (TOGA COARE) Intensive Observing Period. The model simulates the formation of pr...
