On the seasonal cycles and variability of Florida Straits, Ekman and Sverdrup transports at 26° N in the Atlantic Ocean [PDF]
Ocean Science, 2010 Since April 2004 the RAPID array has made continuous measurements of the Atlantic Meridional Overturning Circulation (AMOC) at 26° N. Two key components of this system are Ekman transport zonally integrated across 26° N and western ...

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.

Heat transport in rotating convection without Ekman layers [PDF]
Physical Review E, 2009 Numerical simulation of rotating convection in plane layers with free slip boundaries show that the convective flows can be classified according to a quantity constructed from the Reynolds, Prandtl and Ekman numbers. Three different flow regimes appear: Laminar flow close to the onset of convection, turbulent flow in which the heat flow approaches the ...

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 ...

IOP Conference Series: Earth and Environmental Science, 2021 Abstract Arafura sea is located between the southern part of Papua Island and Aru Island. Previous studies on Sea Surface Temperature (SST) have described that the SST is strongly affected by the upwelling, but the effect of Ekman Mass Transport (EMT) and Ekman Pumping Velocity (EPV) has not yet been studied.

PLoS ONE, 2017 This study analyzes two wind-induced upwelling mechanisms, namely, Ekman transport and Ekman pumping that occur during the southwest monsoon. The results suggest that the coastline of the east coast of Peninsular Malaysia (ECPM) is affected by upwelling ...

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 ...

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 ...
