Seasonal variability of the Ekman transport and pumping in the upwelling system off central-northern Chile (∼ 30° S) based on a high-resolution atmospheric regional model (WRF) [PDF]
Ocean Science, 2016 Two physical mechanisms can contribute to coastal upwelling in eastern boundary current systems: offshore Ekman transport due to the predominant alongshore wind stress and Ekman pumping due to the cyclonic wind stress curl, mainly caused by the abrupt ...

Horizontal Gravity in Ocean Ekman transport [PDF]
, 2021 Abstract Three-dimensional gravity vector field g (= igλ+jgφ+kgz) in geodesy has been greatly simplified to a uniform vertical vector (-g0k) in oceanography with (λ, φ, z) the (longitude, latitude, height), (i, j, k) the corresponding unit vectors, and g0 = 9.81 m/s2. Recent studies by the author show such simplification incorrect.

On the numerical resolution of the bottom layer in simulations of oceanic gravity currents [PDF]
Ocean Science, 2010 The role of an increased numerical vertical resolution, leading to an explicit resolution of the bottom Ekman layer dynamics, is investigated. Using the hydrostatic ocean model NEMO-OPA9, we demonstrate that the dynamics of an idealised gravity current ...

Influence of Stratification and Bottom Boundary Layer on the Classical Ekman Model
Journal of Marine Science and Engineering, 2022 A depth understanding of the different processes of water movements produced by the wind surface stress yields a better description and improvement of the marine food chain and ecosystem. The classical Ekman model proposes a hypothetical ocean, excluding

Nonlocal and local wind forcing dependence of the Atlantic meridional overturning circulation and its depth scale [PDF]
Ocean Science, 2022 We use wind sensitivity experiments to understand the wind forcing dependencies of the level of no motion as the depth of maximum overturning and the e-folding pycnocline scale, as well as their relationship to northward transport of the mid-depth ...

Wind-Controlled Transport of Saltwater in the Southeastern Baltic Sea: A Model Study
Frontiers in Marine Science, 2022 We hypothesized that the saltwater transport in a system of the southeastern Baltic basins including the Gdańsk and Gotland deeps connected by the Hoburg Channel, is greatly controlled by wind forcing, which has a clear physical explanation.

Ekman Transport as the Driver of Extreme Interannual Formation Rates of Eighteen Degree Water [PDF]
Journal of Geophysical Research: Oceans, 2022 AbstractIn the North Atlantic subtropical gyre, the Eighteen Degree Water (EDW) is a voluminous heat reservoir, submerged under a seasonal pycnocline that can be progressively removed through the winter, allowing EDW ventilation in the early spring. We target the EDW formation extremes, namely 2004–2005, 2009–2010, and 2012–2013 for the strong years ...

Major variations in subtropical North Atlantic heat transport at short (5 day) timescales and their causes [PDF]
, 2016 Variability in the North Atlantic ocean heat transport at 26.5°N on short (5-day) timescales is identified and contrasted with different behaviour at monthly intervals using a combination of RAPID/MOCHA/WBTS measurements and the NEMO-LIM2 1/12° ocean ...
