A systematic method of estimation of alongshore windstress and Ekman transport associated with coastal upwelling [PDF]

open access: yesMethodsX, 2023
A standard method for estimating alongshore windstress (AWS) and related cross-shore Ekman transport (ET) is proposed. In the absence of standard methodologies for estimating coastal angles required for AWS estimation, an estimation is typically derived ...

Estimating zonal Ekman transport along coastal Senegal during passage of Hurricane Fred, 30–31 August 2015

open access: yesSN Applied Sciences, 2021
We examine the role of zonal Ekman transport along the coast of Senegal on 30 August 2015 when the tropical disturbance associated with Tropical Cyclone Fred was located to the west of Senegal, causing considerable coastal damage in the southern Senegal ...

The partitioning of poleward energy transport response between the atmosphere and Ekman flux to prescribed surface forcing in a simplified GCM

open access: yesGeoscience Letters, 2018
Recent studies have indicated that ocean circulation damps the atmospheric energy transport response to hemispherically differential energy perturbations, thereby muting the shifts of the Inter-Tropical Convergence Zone (ITCZ).

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

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 ...

On the numerical resolution of the bottom layer in simulations of oceanic gravity currents [PDF]

open access: yesOcean 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 ...

Spatiotemporal trends in the southwest monsoon wind-driven upwelling in the southwestern part of the South China Sea.

open access: yesPLoS 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 ...

Extension of Ekman (1905) wind-driven transport theory to the β plane [PDF]

open access: yesOcean Science, 2023
The seminal Ekman (1905) f-plane theory of wind-driven transport at the ocean surface is extended to the β plane by substituting the pseudo-angular momentum for the zonal velocity in the Lagrangian equation. When the β term is added, the equations become

Influence of Stratification and Bottom Boundary Layer on the Classical Ekman Model

open access: yesJournal 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
