Sentences with phrase «cold deep waters flowing»

The Atlantic Meridional Overturning Circulation (AMOC)-- characterized by warm surface waters flowing northward and cold deep waters flowing southward throughout the Atlantic basin — is defined as the zonal integral of the northward mass flux at a particular latitude.

In red the relatively warm surface flow is seen, in blue the cold deep water flow.

Not exact matches

Today, cold water sinks near the Arctic and flows deep below the surface of the Atlantic toward the southern oceans, where it rises up.

The models reveal a «hydrothermal siphon» driven by heat loss from deep in the Earth and the flow of cold seawater down into the crust and of warmed water up out of the crust.

One result is a flow of cold deep water toward the equator and warm surface water toward the poles, and this «overturning circulation» plays a crucial role in moving heat around the globe.

Both of the recorded winters were unusually cold and created similarly large amounts of deep water, but the strength of the AMOC whipsawed wildly between 8 and 25 sverdrups, a unit of flow roughly equivalent to the total flow of all the world's rivers.

Thus it appears that disruption of deep water formation in the North Atlantic, via a blob of colder fresher water coming off of Greenland, would not «shut down» or even affect the Gulf Stream net mass transport at all, but instead would shift its northern return flow southwards, with many severe regional consequences.

The Atlantic overturning is driven by the differences in the density of the ocean water: when the warm, lighter water flows from south to north it becomes colder, denser and heavier, making it sink deeper and flow back southwards.

Enhanced north / south blocking patterns in periods of low solar activity enhance flow in the Peruvian and Californian Currents facilitating increased eastern Pacific upwelling of cold and nutrient rich water from the deep ocean.

In addition, under the surface, deep cold waters which have sunk in the arctic are moving south and returning the net flow northwards on the surface.

Turbulent deep ocean flows surface and set up wind and current responses that again extend the cold tongue and piles warm surface water up against Australia and Indonesia.

The cold water at the poles sinks, flows equatorwards across the ocean deeps.

Atlantic Meridional Overturning Circulation A major current in the Atlantic Ocean, characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder water in the deep Atlantic.

If Arctic waters become fresh this inhibits the flow of cold arctic waters to the depths warming the deep oceans.

Heat does transfer from the warmer upper part of the ocean to the deeper cooler part, not the other way around as you claim, but it's balanced by flows of cold water descending into the deep ocean near the poles.

On the other side, the oceanographer Wallace Broecker [Broecker, 1997] has argued that the present warm climate in Europe depends on a circulation of ocean water, with the Gulf Stream flowing north on the surface and bringing warmth to Europe, and with a counter-current of cold water flowing south in the deep ocean.
