True Gravity in Ocean Dynamics Part 1 Ekman Transport [PDF]

Dynamics of Atmospheres and Oceans, 2021
Abstract The direction normal to the Earth spherical (or ellipsoidal) surface is not vertical (called deflected vertical) since the vertical direction is along the true gravity g (= igλ+ jgφ+ kgz). Here, (λ, φ, z) are (longitude, latitude, depth), and (i, j, k) are the corresponding unit vectors.

Ekman Transport Patterns in the Area Close to the Galician Coast (NW, Spain)

Vital, 2005
A 40 year time series of daily and monthly Ekman transport is analysed in an oceanic area 150 km offshore Cape Finisterre (43°N, 11°W). The periodicity of the signal showed an annual component (365 days), a seasonal fluctuation (50 days) and a time scale related to passing storms (20 days). The Ekman transport showed different seasonal patterns.

Wind-Driven Ocean Currents and Ekman Transport

Science, 1987
Oceanographers have long sought to verify the theoretical Ekman transport relation, which predicts that a steady wind stress acting together with the Coriolis force will produce a transport of water to the right of the wind. In situ measurements of wind and ocean currents provide a detailed view of this phenomenon. By separating the wind-driven current

Contribution of Ekman Transport to the ENSO Periodicity Estimated With an Extended Wyrtki Index

Geophysical Research Letters, 2021
Abstract Off‐equatorial wind stress curl anomalies that mainly drive geostrophic transport are essential for the phase transition of the El Niño‐Southern Oscillation (ENSO) induced by a recharge‐discharge process. The ENSO‐induced zonal wind stress anomaly also drives surface Ekman currents, which may counteract the geostrophic ...

Role of Ekman Transport Versus Ekman Pumping in Driving Summer Upwelling in the South China Sea

Journal of Ocean University of China, 2013
Relative roles of Ekman transport and Ekman pumping in driving summer upwelling in the South China Sea (SCS) are examined using QuikSCAT scatterometer wind data. The major upwelling regions in the SCS are the coastal regions east and southeast of Vietnam (UESEV), east and southeast of Hainan Island (UESEH), and southeast of Guangdong province (USEG ...

Anthropogenic Carbon Dioxide Transport in the Southern Ocean Driven by Ekman Flow

Nature, 2010
The Southern Ocean, with its large surface area and vigorous overturning circulation, is potentially a substantial sink of anthropogenic CO(2) (refs 1-4). Despite its importance, the mechanism and pathways of anthropogenic CO(2) uptake and transport are poorly understood.

Nonlinear Damping of ITCZ Migrations Due to Ekman Ocean Energy Transport

Geophysical Research Letters, 2020
AbstractThe role of tropical wind‐driven ocean circulation in setting the position of the Intertropical Convergence Zone (ITCZ) is studied using an atmospheric model coupled to a slab ocean with parameterized Ekman energy transport. Unlike previous studies, the parameterized cross‐equatorial ocean energy transport, which is critical for the coupled ...

The Effect of Stokes Drift on Ekman Transport in the Open Sea

Acta Oceanologica Sinica, 2012
By introducing the wave-induced Coriolis-Stokes forcing into ageostrophic motion equation, the Eulerian transport is modified by the wave-induced Stokes drift. The long-term mean contributions of the Stokes transport with remotely generated swells being included to the ageostrophic transport are analyzed using the ECMWF (European Centre for Medium ...
