Adjustment of the basin-scale circulation at 26 degrees N to variations in Gulf Stream, deep western boundary current and Ekman transports as observed by the Rapid array [PDF]

, 2009
The Rapid instrument array across the Atlantic Ocean along 26 degrees N provides unprecedented monitoring of the basin-scale circulation. A unique feature of the Rapid array is the combination of full-depth moorings with instruments measuring temperature,

The effect of Ekman mass transport and Ekman pumping velocity on the variability of sea surface temperature in the Arafura Sea

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.

A nonlinear model for rotationally constrained convection with Ekman pumping

, 2016
It is a well established result of linear theory that the influence of differing mechanical boundary conditions, i.e., stress-free or no-slip, on the primary instability in rotating convection becomes asymptotically small in the limit of rapid rotation ...

Surface mixing and biological activity in the four Eastern Boundary Upwelling Systems [PDF]

, 2009
Eastern Boundary Upwelling Systems (EBUS) are characterized by a high productivity of plankton associated with large commercial fisheries, thus playing key biological and socio-economical roles.

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

Journal 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 ...

A fast and physically grounded ocean model for GCMs: the Dynamical Slab Ocean Model of the Generic-PCM (rev. 3423) [PDF]

Geoscientific Model Development
We present an improved dynamical slab ocean model implemented in a 3-D General Circulation Model (GCM) called the Generic Planetary Climate Model (Generic-PCM; formerly the LMD-Generic GCM).

Boundary Zonal Flow in Rotating Turbulent Rayleigh-Bénard Convection [PDF]

, 2019
For rapidly rotating turbulent Rayleigh–Bénard convection in a slender cylindrical cell, experiments and direct numerical simulations reveal a boundary zonal flow (BZF) that replaces the classical large-scale circulation.

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

Journal 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 Role of Coastal Upwelling in Suppressing the Warming Trend of Sea Surface Temperature along the Southern Coast of Java

Ilmu Kelautan
This study examines the unclear role of wind-driven upwelling through Ekman transport and pumping, along with the combined effects of the Indian Ocean Dipole (IOD) and El Niño-Southern Oscillation (ENSO) trends on the warming rate of Sea Surface ...

The effects of Ekman pumping on quasi-geostrophic Rayleigh-Benard convection

, 2016
Numerical simulations of 3D, rapidly rotating Rayleigh-Benard convection are performed using an asymptotic quasi-geostrophic model that incorporates the effects of no-slip boundaries through (i) parameterized Ekman pumping boundary conditions, and (ii) a
