A. Wind-Driven Circulation The circulation in the ocean can usually be divided usefully into the thermocline region 0 - m and deep sea flows below this region. The subsurface circulation above the main pycnocline is strongly influenced by wind forcing. Thus the general wind-driven flow pattern above the thermocline (i.e., pycnocline). This book commemorates the 70th birthday of Eugene Morozov, the noted Russian observational oceanographer. It contains many contributions reflecting his fields of interest, including but not limited to tidal internal waves, ocean circulation, deep ocean currents, and Arctic oceanography.

An ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. Depth contours, shoreline configurations, and interactions with other currents influence a current's direction and strength. Ocean currents are primarily horizontal water.

Wind-driven circulation on a shallow, stratified shelf by Jay Alan Austin Download PDF EPUB FB2

A model of wind driven circulation in a shallow sea is devised, where two components of sea current due to wind stress and water slope are given. The central problem, found in every wind current model, that is the turbulent exchange of momentum in vertical direction, is also solved here.

The solution is based on the equation of turbulent by: 9. circulation, advectively driven circulation, and horizontal mixing circulation. They found that the lateral advection can be a major driving force for the estuarine circulation in some estuaries.

This motives us to examine the effects of the lat-eral flows on the wind-driven flows in the along-channel direction.

define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by exchange of ocean heat and water with the atmosphere, inducing.

A theory of wind-driven circulation. Mid-ocean gyres initially stratified but motionless, adjusts to a suddenly applied wind stress is examined. Circulation on the shelf is essentially. In the stratified rotating estuary of Chesapeake Bay, the Ekman transport drives a counterclockwise lateral circulation under down?estuary winds and a clockwise lateral circulation under up?estuary winds (looking into estuary).

The clockwise circulation is about twice as strong as the counterclockwise circulation. Analysis of the streamwise vorticity equation reveals a balance among three.

circulation and the wind-driven variations of the circulation remain to be described for the CH estuary. Since these aspects of the circulation largely control both the stratifica-tion and the related state variable distributions, a more complete understanding of the circulation is necessary to support multidisciplinary ecological by: BOREAL ENV.

At first glance, most estuaries are governed by tidal oscillation and influenced by river discharges, so mixing processes account for most of the hydrodynamic characterization of estuaries.

pressure gradient in shallow waters, shifting to a balance between the Coriolis force and the wind stress terms in deeper waters. Introduction Wind-driven shelf circulation investigations have focused their attention on the effects of along-shelf winds, which result in upwelling or by: 5.

Confirmation of one of the oldest theories of the wind-driven circulation (due to Ekman), and one on which ocean circulation models are based, eluded oceanographers until the last decade, although the success of Ekman's theory in predicting the dominant features of the circulation has long provided indirect confirmation (Chereskin and Price, ).

The circulation and salt balance in the Albemarle-Pamlico Sound (APS) are investigated using a 3D hydrodynamic model. Aug 20,  · In the southern portion of the shelf, there is weakening of the northward, inner-shelf jet during the spring and a reversal of the outer-shelf circulation from a southward direction during the fall toward a northward direction during the spring.

There are no significant seasonal variations of the wind-driven circulation south of ∼50°S. CHAPTER THE WIND-DRIVEN CIRCULATION Figure The ocean comprises a warm, salty, stratified lens of fluid, the ther- mocline, circulating on top of a cold, fresh, relatively well mixed, abyss.

The surface layer, above the horizontal dotted line at a depth of about m,isdriven directly by the wind. The tides vary locally, but will in general add only little to the net water transport.

Therefore the wind-generated and estuarine circulations, are important for the exchange of water between fiords and the outside shelf. The wind-driven circulation is dictated by the. Jun 05,  · It has been 24 years since Pratt () published his book on the physical oceanography of straits.

Research on the dynamics of straits has much advanced since that time and the literature is wide and scattered. Thus we first aim to provide a short review of the circulation in straits, focusing on the key processes controlling the net circulation with an emphasis on shallow by: On continental shelves the classical Ekman upwelling circulation does not reach into shallow waters of the inner continental shelf.

Instead, upwelling close to shores generally follows from offshore wind. This offshore wind moves water away from the shore and triggers a situation in which the water surface tends to slope against the wind by: 2. What are the two major types of ocean circulation.

The inner continental shelf, which spans water depths of a few meters to tens of meters, is a dynamically defined region that lies between the surf zone (where waves break) and the middle continental shelf (where the along-shelf circulation is usually in geostrophic balance).
