Sentences with phrase «cold deep water»

Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific, she said.

Consider, as you say, that «If the warm water heated by the sun is driven by the wind into the deeper layers, and also bringing colder deep waters to the surface, the surface stays cool, the heat is transferred down...» If we agree that oceanic warming (especially at depth) means more heat in the overall system without a corresponding increase in its radiative efficacy, then from a systems point of view, La Nina warms, not cools.

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.

However, in their wake, hurricanes set up large - amplitude waves that mingle warm surface water with colder deep water, says climate scientist Matthew Huber of Purdue University.

Scientists thought strong upwelling of colder deep waters spared the region from the warming seen in other parts of the Pacific, she says.

Between 2 and 3 million years ago the cooling of the deep oceans reached a tipping point, and modern upwelling regions ogf cold deep water off the coast of Peru, California and the west coast of Africa were established.

The nightly migration of zooplankton from the thermocline [a layer of water in the ocean that marks the transition from warmer surface waters to colder deep waters] to the surface, we saw that.

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.

OTEC is a relatively marginal alternative energy source that uses cold deep water and warm surface water to run the equivalent of a reverse fridge cycle.

Arrays monitor circulating currents in the Atlantic Ocean, in which warm shallow waters move north (red), while cold deep waters move south (blue).

When the wind - driven ocean circulation is intense, such as during the negative phase of the IPO & La Nina, there is strong upwelling of cold deep water along the equator, and along the eastern coasts of the continents.

12 vertical density currents that occur when cold deep water comes to the surface can occur anywhere, prevalent along western coasts of continents

They identified wind patterns that mixed the warmer surface and colder deep waters to cool the ocean's surface and reduce the intensity of the storm.

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

Stronger trade winds push warm surface water towards the west, and bring cold deeper waters to the surface to replace them.

This raises the thermocline (boundary between warm surface water and cold deep water), and increases the amount of heat stored in the upper few hundred meters of the ocean.

[Response: It's not so much that the warmer water is pushed to the warm pool, as that the wind pattern thickens the warm layer, making it harder for upwelling to tap into the colder deeper waters.

The BWT peaks are followed by an abrupt drop in temperature at the onset of interstadials, indicating the abrupt start of convection and renewed generation of cold deep water.

It is this colder deeper water reaching the surface waters that restrains an increase in GMST to less than that naively expected from solar or atmosperic changes just as it is warmer water rising to the surface (such as, obviously, El Nino) that boosts an increase in GMST to more than that naively expected from solar or atmosperic changes.

It is not that heat enters the oceans which could reduce an increase in GMST, it is that colder deeper water must rise to the surface if warmer surface waters are being pushed downwards.

Re # 134 AK, as you point out, cold deep water brought to the surface will sink unless it is distributed widely enough to mix with the surface water and reach an equilibrium temperature that will keep it near the top.
