Ekman Transport in Balanced Currents with Curvature [PDF]

open access: yesJournal of Physical Oceanography, 2017
AbstractEkman transport, the horizontal mass transport associated with a wind stress applied on the ocean surface, is modified by the vorticity of ocean currents, leading to what has been termed the nonlinear Ekman transport. This article extends earlier work on this topic by deriving solutions for the nonlinear Ekman transport valid in currents with ...

A Bound on Ekman Pumping [PDF]

open access: yesJournal of Advances in Modeling Earth Systems, 2020
Momentum transport by boundary layer turbulence causes a weak synoptic‐scale vertical motion. The classical textbook solution for the strength of this Ekman pumping depends on the curl of the surface momentum flux.

On the seasonal cycles and variability of Florida Straits, Ekman and Sverdrup transports at 26° N in the Atlantic Ocean [PDF]

open access: yesOcean 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]

open access: yesOcean 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 ...

Rigorous bounds on the heat transport of rotating convection with Ekman pumping [PDF]

open access: yesJournal of Mathematical Physics, 2020
We establish rigorous upper bounds on the time-averaged heat transport for a model of rotating Rayleigh-Bénard convection between no-slip boundaries at infinite Prandtl numbers and with Ekman pumping. The analysis is based on the asymptotically reduced equations derived for rotationally constrained dynamics with no-slip boundaries, and hence, includes ...

The Impact of Ekman Pumping and Transport on Dosidicus gigas (Jumbo Flying Squid) Fishing Ground by Chinese Jiggers off the Coast of Peru [PDF]

open access: yesJournal of Marine Science and Engineering
Upwelling is often associated with high productivity, biodiversity, and fishery resource abundance. This study employed a generalized additive model (GAM) to analyze the effects of Ekman pumping and transport on the abundance and distribution of jumbo ...

Global simulation : Ekman + Geostrophic transport [PDF]

open access: yes, 2021
Global simulation including Ekman and geostrophic transport. Created using the Ocean Parcels framework (https://oceanparcels.org/) The simulation was started with a uniform input distribution, with particles every 1 degree (34,515 particles total). All

On the meridional ageostrophic transport in the tropical Atlantic [PDF]

open access: yesOcean Science, 2017
The meridional Ekman volume, heat, and salt transport across two trans-Atlantic sections near 14.5° N and 11° S were estimated using in situ observations, wind products, and model data. A meridional ageostrophic velocity was obtained as the difference

Ekman-Inertial Instability [PDF]

open access: yes, 2020
We report on an instability, arising in sub-surface, laterally-sheared geostrophic flows. When the lateral shear of a horizontal flow in geostrophic balance is of opposite sign to the Coriolis parameter, and exceeds it in magnitude, embedded ...

Pengaruh Ekman Mass Transport dan Ekman Pumping Velocity Terhadap Upwelling di Perairan Selatan Pulau Bali-Sumbawa [PDF]

open access: yes, 2023
Upwelling merupakan pengangkatan massa air laut dari perairan yang lebih dalam ke permukaan. Massa air tersebut membawa banyak nutrien yang selanjutnya akan mempengaruhi pertumbuhan fitoplankton.
