Not exact matches

Furthermore, even if the net meridional overturning circulation, which is broader than just the Gulf Stream, slows, that doesn't mean that the poleward heat transport will be reduced, as a warmer wetter atmosphere can also transport a great deal of heat (latent heat) to poleward regions, which seems to be what has been happening.

This paper is an assessment of the current climate poleward heat transport.

Changes here have a long term effect, affecting the strength of the north - ward horizontal flow of the Atlantic's upper warm layer, thereby altering the oceanic poleward heat transport and the distribution of sea surface temperature (SST — AMO), the presumed source of the (climate) natural variability.

As the ocean circulation takes up the role of transporting heat poleward the atmospheric circulation spins down.

Scientists are still trying to decide how the poleward heat transport will be affected by global warming — but the rapid changes at the poles seem to involve a lot of heat transport into that region via both the atmosphere and the oceans.

Is less poleward transport of heat by the Gulf Stream as the AMOC weakens a positive feedback for global warming, since that energy will escape more slowly in the humid (higher water vapor GHG effect) tropics than near the poles?

You have variations in poleward heat transport and a change in the intensity of Sudden Stratospheric Warming events.

Although more research is needed, there is some agreement among oceanographers that, for the entire area north of 30 N latitude, the ocean's poleward transport of heat is the equivalent of about 15 watts per square metre of the earth's surface (W / m2).

Temperatures there are strongly dependent upon poleward transport of heat.

The vertical transfer of energy is directly proportional to the poleward transport or advection of heat.

If you have faith in the climate models and have any knowledge of what they do with reduced poleward ocean heat transport, then you are expecting cooling unless the AMOC should speed back up.

John Wise - it seems to a be natural phenomenon tied to the poleward transport of heat.

Conversely, during low solar activity during the Little Ice Age, transport of warm water was reduced by 10 % and Arctic sea ice increased.17 Although it is not a situation I would ever hope for, if history repeats itself, then natural climate dynamics of the past suggest, the current drop in the sun's output will produce a similar cooler climate, and it will likely be detected first as a slow down in the poleward transport of ocean heat.22 Should we prepare for this possibility?

In our model simulations this weakens the AMOC and poleward ocean heat transport, and diminishes the contribution of ocean heat transport to the reduction of Arctic sea ice extent.

The conventional view on the connection between the AMOC and Arctic sea ice is that a weakening of the AMOC should reduce ocean poleward heat transport and, hence, expand sea ice.

They forced the model with CO2 and happened to catch it when it was in the process of increasing poleward ocean heat transport.

Warm currents transport heat from lower latitudes poleward and tend to occur on the western sides of oceans.

Put another way, a warmer climate will place greater demands on the atmosphere to transport heat upward and poleward, but this will be done more efficiently, in a smaller number of events that each accomplish more of the required transport.

In which case, half of the global warming in the last three decades is due to the negative feedback of increased poleward oceanic heat transport as a result of weaker solar activity.

The Arctic responds strongly through teleconnections controlling the rates of poleward oceanic and atmospheric heat transport.

These oscillations are superimposed on a long term trend of increasing poleward ocean heat transport.

All of the warming since the LIA can easily be explained by increases in poleward ocean heat transport.

Waters moving in the western boundary currents adjacent to the major gyres (North and South Pacific and Atlantic basins and the Indian basin) transport large quantities of heat poleward from the tropics.

To ascertain with confidence the extent to which deep water production impacts the ocean's meridional circulation and hence the ocean's contributions to the global poleward heat flux, continuous measures of trans - basin mass and heat transports are needed.

MOCHA array — provide a means to evaluate intergyre connectivity within the North Atlantic and allow for a determination of how and whether deep water mass formation impacts overturning and poleward heat and freshwater transports throughout the North Atlantic.

Additionally, the intensified winds of the mid-latitude westerlies, and a poleward shift of the strongest winds toward the Antarctic Circumpolar Current will also lead to stronger convergence of surface currents, and stronger downward heat transport.

While the baroclinic systems are efficient in transporting heat, the enormous negative radiative forcing (Fig. 2) associated with these cloud systems seems to undo the poleward transport of heat by the dynamics.

However, the mechanism of increased poleward heat transport can not be the only physical mechanism driving the reduced temperature gradient because it is in fact the surface temperature gradient that ultimately drives the flux of heat poleward.

Most of the observed decline in the latitudinal temperature gradient during the Pliocene can be explained by increased poleward heat transport.

back to the horizontal gradient, if the upper tropospheric thermal wind shear increase is greater than the decrease of the lower layer, then maybe the overall baroclinic instability would be stronger — but currently the upper level eddy circulations do not transport much heat poleward, so would the structure of cyclones change so that a deeper layer of air is involved in the thermal advection, compensating for a weaker temperature gradient?

Furthermore, even if the net meridional overturning circulation, which is broader than just the Gulf Stream, slows, that doesn't mean that the poleward heat transport will be reduced, as a warmer wetter atmosphere can also transport a great deal of heat (latent heat) to poleward regions, which seems to be what has been happening.

On Earth this happens close to 30 degrees latitude, and poleward of this the heat transport is dominated by mid-latitude eddies rather than being under the wings of a giant overturning circulation (you can still find references to a mid-latitude «Ferrell cell» in textbooks, but this is not a good description of what happens).
