Decadal Evolution of Ocean Thermal Anomalies in the North Atlantic: The Effects of Ekman, Overturning, and Horizontal Transport [PDF]
Journal of Climate, 2014 Basin-scale thermal anomalies in the North Atlantic, extending to depths of 1–2 km, are more pronounced than the background warming over the last 60 years.

Offshore Ekman transport and Ekman pumping off Peru during the 1997–1998 El Niño [PDF]
Geophysical Research Letters, 2002 Satellite ocean vector wind measurements are used to describe onshore‐offshore Ekman transport and Ekman pumping/suction (i.e., downward/upward velocity) in the coastal ocean at 15°S off Peru, where upwelling is the dominant physical process. Normal and El Niño conditions are defined for May 1992 – April 1997 and May 1997 – May 1998, respectively ...

True gravity in ocean dynamics Part 1 Ekman transport
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.

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 ...

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 ...

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 ...

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 ...
