Upwelling age: an indicator of local tendency for coastal upwelling

Journal of Oceanography, 2011
A proxy named “upwelling age”, defined as the ratio of wind time scale to “advection time”, was developed to quantify the local tendency for coastal upwelling. The formulation of the “advection time” was derived from Ekman theory. A 3D numerical model was used to validate and refine the theoretical formula by simulating a total of 30 cases of different

The Peruvian-Chilean Coastal Upwelling System

, 2016
This chapter describes the Peruvian-Chilean coastal upwelling system which is by far the most productive system in terms of pelagic fish among the Big Four coastal upwelling systems—a feature that is known as the Peruvian Puzzle. Also discussed are fluctuations of fish and bird abundance in the context of the El Nino Southern Oscillation, overfishing ...

Greenhouse gas, upwelling‐favorable winds, and the future of coastal ocean upwelling ecosystems

Global Change Biology, 2010
AbstractCoastal ocean upwelling ecosystems generally represent the most productive large marine ecosystems of the world's oceans, in terms of both primary production rates and tonnages of exploitable fish produced. The Peruvian upwelling system, in particular, stands out as a major factor in world fish production.

A documentary proxy for coastal upwelling

2023
Coastal upwelling is a process in which sea water from intermediate depths emerges along the west coast of continents in response to the intensity of the alongshore component of the wind. These areas are economically relevant as upwelled water is rich in nutrients, creating regions of great interest for fisheries.Quantifying upwelling intensity at ...

A Cyclesonde View of Coastal Upwelling

Journal of Physical Oceanography, 1976
Abstract In August 1973, 320 vertical profiles of temperature and horizontal velocity were recorded during a 64 h period by an array of three Cyclesondes in the coastal upwelling region off Oregon. The mean interior along-shore velocity was geostrophic and a linear function of density, with a near-surface, equatorward jet at mid-shelf, and a poleward ...

A Numerical Model of Coastal Upwelling

Journal of Physical Oceanography, 1972
Abstract A wind-driven model of coastal upwelling induced into a stratified, rotating ocean is solved numerically. The circulation is on an f plane and longshore variations are neglected. A multilevel model is derived, but only solutions for a two-layer model are discussed. A longshore baroclinic surface jet is discovered.
