transporting, or risk the hot
water leaking from the cap.
These large Northern Hemisphere cooling events have previously been linked to a change in the Atlantic Ocean circulation that led to a reduced
transport of
warm water to the high latitudes in the North.
Japan, the east coast of the US, northern Brazil and south eastern Africa are also strongly influenced by coastal currents that
transport warm tropical
waters.
As the oceans have
warmed and the climate has changed, hotspots are developing in regions where the currents that
transport warm tropical
waters towards the poles are strengthening.
«As the climate gets
warmer, the thawing permafrost not only enables the release of more greenhouse gases to the atmosphere, but our study shows that it also allows much more mineral - laden and nutrient - rich
water to be
transported to rivers, groundwater and eventually the Arctic Ocean,» explained Ryan Toohey, a researcher at the Interior Department's Alaska Climate Science Center in Anchorage and the lead author of the study.
Warm and saline
water transported poleward cools at the surface when it reaches high latitudes and becomes denser and subsequently sinks into the deep ocean.

Transport your mind to a realm of
warm crystalline
waters where fascinating wrecks and playful sea lions await you.
Conceptually, it's hard to see how the Gulf Stream western boundary current could be weakened by conditions around Greenland; this is a fluid dynamics system, not a mechanical «belt»; a backup due to less deep
water formation should have little effect on the physics of the gyre and the formation of the western boundary current, and it also seems the tropical
warming and the resulting equator - to - pole heat
transport are the drivers — but perhaps modulation by jet stream meandering is playing some role in the cooling?
There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep
water formation where excessive
warming patterns are changed, 2) enhancing (local convective scale) deep
water formation where the changed excessive
warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep
water formation locations as a result of a) shifted patterns of enhanced
warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which
transport these enhanced ocean features to critically altered destinations.
In addition, it's hard to say how the wind - driven Atlantic gyre (whose western intensification drives the Gulf Stream's
transport of
warm salty
water northward) will affect a weakened northern end of the AMOC.
As more
warm water is
transported north, the cooler
water sinks and moves south to make room for the incoming
warm water.
Consenquently, the associated SST pattern is slightly cooler in the deep convection upwelling regions of the Equitorial Pacific and the Indian Ocean, strongly cooler in the nearest deep convection source region of the South Atlantic near Africa and the Equator,
warm over the bulk of the North Atlantic, strongly
warmer where the gulf stream loses the largest portion of its heat near 50N 25W, and strongly cooler near 45N 45W, which turns out to be a back - eddy of the Gulf Stream with increased
transport of cold
water from the north whenever the Gulf Stream is running quickly.
Finally, to return to the original issue, I think that most of the
water borne fraction of the heat
transport that makes the UK and Europe anomalously
warm is in the GSC.
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?
The surface
waters of the tropical Atlantic are then
transported, via the Gulf Stream, towards the high latitudes where they
warm the atmosphere before plunging into the abysses in the convection zones situated in the seas of Norway, Greenland and Labrador.
Dr. Czimczik cautioned that her study was a small one conducted only in Southern California, an area where
water has to be
transported from afar and lawns have to be maintained year - round because of the
warm climate.
So when you
transport enormous amounts of
warm tropical
waters to the poles for about 400,000 years, you end up with ice ages, which after a while may shut down the MOC again, further increasing the polar cooling, as for instance happened at the Younger Dryas.
This mass of
warm water, nicknamed «the Blob,» was the result of a persistent atmospheric high - pressure ridge in the Northeastern Pacific that decreased cooling and
transport of surface
water.
However the negative NAO also implies a spin - down of the subtropical gyre and therefore a drop in the pole - ward
transport of
warm tropical
waters.
illustrating the correlation between the pole - ward
transport of
warm tropical
water and the North Atlantic Oscillation.
The notion of an H2O positive feedback (which probably is present on a clear day) is squashed by this process.While
warmer air can hold exponentially more
water vapor, presumably increasing greenhouse effects (an process the IPCC hangs its collective hat on), it is also this exact same property that vastly improves the chances of convective and phase change heat
transport by thunderstorms.
A strengthening ACC created a barrier inhibiting intrusions of
warm tropical
waters and minimizing both oceanic and atmospheric heat
transport resulting in the Refrigerator Effect.
I argued that Greenland's glaciers would soon stabilize and sea ice in the Barents Sea would soon recover based on trends in the
transport of
warm Atlantic
water into the Arctic.
The amount of
warm water entering the Irminger Current is particularly limited because the sub-Polar gyre also shunts the pole - ward
transport to the east towards the Barents Sea.
Some of the
water though is presently observed to form giant (up to 300 km) eddies, that round the cape and
transport warm water masses westwards into the Atlantic.
Warm surface
water flows from the tropical South Atlantic, through the Caribbean, and is then
transported, via the Gulf Stream and North Atlantic Drift, to the northernmost North Atlantic.
A greater - than - normal volume of
warm salty tropical

It is analogous to the Gulf Stream in the Atlantic Ocean,
transporting warm, tropical
water northward towards the polar region.
The Atlantic Meridional Overturning Circulation (AMOC)- the
transport of
warm tropical surface
water northward - is indeed propelled by dense
water sinking in the North Atlantic and travelling equatorward in the deeper layers, but it also has a wind - driven component to it.
But equally important changes in insolation affected the volume of
warmer tropical
waters that were
transported toward the poles.
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?
So
warmer - than - normal surface
waters in the South Atlantic created by the changes in atmospheric circulation during an El Niño should be
transported northward into the North Atlantic (and vice versa for a La Niña).
Storms help replenish
warm water next to the ice, and help carry addtional heat into the melting region via atmospheric
transport of
warmer moist air.
AGW climate scientists seem to ignore that while the earth's surface may be
warming, our atmosphere above 10,000 ft. above MSL is a refrigerator that can take
water vapor scavenged from the vast oceans on earth (which are also a formidable heat sink), lift it to cold zones in the atmosphere by convective physical processes, chill it (removing vast amounts of heat from the atmosphere) or freeze it, (removing even more vast amounts of heat from the atmosphere) drop it on land and oceans as rain, sleet or snow, moisturizing and cooling the soil, cooling the oceans and building polar ice caps and even more importantly, increasing the albedo of the earth, with a critical negative feedback determining how much of the sun's energy is reflected back into space, changing the moment of inertia of the earth by removing
water mass from equatorial latitudes and
transporting this
water vapor mass to the poles, reducing the earth's spin axis moment of inertia and speeding up its spin rate, etc..
But these large reservoirs of heat
warm the air over them, that
warm air and
water vapor is then
transported over land, which adds to surface temps.
When we get a arctic season with great cyclones, those cyclones can lead to a break up of the ice (more lateral melting), If currents conspire we end up with more
transport out of the arctic (ice then melts in the
warmer water), and we get Eckmen pumping and more ice melts.
Through horizontal averaging, variations of
water vapor and temperature that are related to the horizontal
transport by the large - scale circulation will be largely removed, and thus the
water vapor and temperature relationship obtained is more indicative of the property of moist convection, and is thus more relevant to the issue of
water vapor feedback in global
warming.
Next year, I expect sea ice free conditions in the Arctic based on heat
transport via
water vapor in the Arctic atmosphere, storm conditions driven by latent heat in the atmosphere, and a good deal of snow this fall that insulates sea ice and permafrost from the cold, thereby allowing them to remain
warm and weak.
The extra boost from the
warmer water is adding even more energy into this storm system, increasing the availability and
transport of moisture toward land and producing more efficient wind gusts to the surface.
The Gulf Stream
transports warm salty
water from the subtropical region to mid-latitudes in the North Atlantic, and changes in its path can have a strong impact on regional marine ecosystems and fisheries.
Do you not believe in vertical ocean circulations or that
warm water can be
transported down by these?
As part of the planet's reciprocal relationship between ocean circulation and climate, this conveyor belt
transports warm surface
water to high latitudes where the
