Sentences with phrase «warm surface waters north»

The deep circulation that drives warm surface waters north is weakening, leading to a cooling of the north Atlantic relative to the rest of the oceans.

Not exact matches

Their results suggest a drop of as much as 10 degrees for fresh water during the warm season and 6 degrees for the atmosphere in the North Atlantic, giving further evidence that the concentration of atmospheric carbon dioxide and Earth's surface temperature are inextricably linked.

The opposite occurred in 1997 and 1998, when warm surface waters in the Pacific Ocean brought about by El Niño pushed rainfall systems north, leaving parts of the southern and eastern Amazon forest dry and prone to fires.

South of Spitzbergen, the oceans have been ice free the past 2 winters, reason being, the warm waters from the Gulf Stream are travelling further north, and closer to the ocean surface, only 25 meters at the last measurement, The ocean temperature has been +2 C instead of -2 C.

In general, the regions of expanding warming upwelling water in the Indian Ocean, North Pacific, or wherever they are, must create slight bulges in the surface, and the regions of shrinking, cooling, sinking water in the Arctic must create slight depressions in the sea surface (again, I mean in a very low pass sense — obviously storms, tides, etc, create all kinds of short - terms signals obscuring this).

Most interesting is that the about monthly variations correlate with the lunar phases (peak on full moon) The Helsinki Background measurements 1935 The first background measurements in history; sampling data in vertical profile every 50 - 100m up to 1,5 km; 364 ppm underthe clouds and above Haldane measurements at the Scottish coast 370 ppmCO2 in winds from the sea; 355 ppm in air from the land Wattenberg measurements in the southern Atlantic ocean 1925-1927 310 sampling stations along the latitudes of the southern Atlantic oceans and parts of the northern; measuring all oceanographic data and CO2 in air over the sea; high ocean outgassing crossing the warm water currents north (> ~ 360 ppm) Buchs measurements in the northern Atlantic ocean 1932 - 1936 sampling CO2 over sea surface in northern Atlantic Ocean up to the polar circle (Greenland, Iceland, Spitsbergen, Barents Sea); measuring also high CO2 near Spitsbergen (Spitsbergen current, North Cape current) 364 ppm and CO2 over sea crossing the Atlantic from Kopenhagen to Newyork and back (Brements on a swedish island Lundegards CO2 sampling on swedish island (Kattegatt) in summer from 1920 - 1926; rising CO2 concentration (+7 ppm) in the 20s; ~ 328 ppm yearly avnorth (> ~ 360 ppm) Buchs measurements in the northern Atlantic ocean 1932 - 1936 sampling CO2 over sea surface in northern Atlantic Ocean up to the polar circle (Greenland, Iceland, Spitsbergen, Barents Sea); measuring also high CO2 near Spitsbergen (Spitsbergen current, North Cape current) 364 ppm and CO2 over sea crossing the Atlantic from Kopenhagen to Newyork and back (Brements on a swedish island Lundegards CO2 sampling on swedish island (Kattegatt) in summer from 1920 - 1926; rising CO2 concentration (+7 ppm) in the 20s; ~ 328 ppm yearly avNorth Cape current) 364 ppm and CO2 over sea crossing the Atlantic from Kopenhagen to Newyork and back (Brements on a swedish island Lundegards CO2 sampling on swedish island (Kattegatt) in summer from 1920 - 1926; rising CO2 concentration (+7 ppm) in the 20s; ~ 328 ppm yearly average

The cold dry winds blowing eastward off Canada eagerly evaporate the warm surface water of the North Atlantic Current, and leave it heavy with excess salt.

The authors postulated that this warm salty water (WSW) layer, situated beneath the colder surface freshwater in the North Atlantic, generated ocean convective available potential energy (OCAPE) over decades at the end of HS1.

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.

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.

Desler, Alexander, and Timlin (1996) said: «A prominent decade - long perturbation in climate occurred during the time period [1970 — 1991] in which surface waters cooled by 1 °C in the central and western North Pacific and warmed by about the same amount along the west coast of North America from late 1976 to 1988.»

It would be surprising if the surface waters of the North Atlantic were not a bit warmer as a result.

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).

Similar processes in the tropical South Atlantic also contribute to the warming of the North Atlantic, since ocean currents carry the warmer - than - normal surface waters from the South Atlantic to the North Atlantic.

The Pentagon report describes a scenario in which human - caused global warming leads to a near - term collapse of the ocean's thermohaline circulation, which brings warm surface waters from the tropics to the North Atlantic, warming parts of Western Europe.

The overturning circulation pushes water through the Atlantic Basin, distributing heat as it moves warmer surface water from the tropics toward Greenland and the high northern latitudes and carries colder, deeper water from the North Atlantic southward.

But winters are long there, so there's still plenty of time, said experts, for the ocean surface to freeze after the water cools and the warm air stops funneling north.

The PDO is a 20 to 30 year pattern of warmer or cooler surface water in the north - east Pacific.

During the warm period, faster currents cause more tropical water to travel to the North Atlantic, warming both the surface and the deep water.

From there, that mass of warm Pacific surface water splits and moves north and south along the coasts of Asia and Australia towards the Poles.

Furthermore, the low - frequency variability in the SPG relates to the propagation of Atlantic meridional overturning circulation (AMOC) variations from the deep - water formation region to mid-latitudes in the North Atlantic, which might have the implications for recent global surface warming hiatus.»

North Atlantic surface warming decreases water density there, thus reducing the rate of sinking.

They flush the cooled surface waters down into the ocean depths, part of a giant conveyor belt that brings more warm surface water into the far north.

Gray first sounded the alarm in 1995, noting that the surface waters in the north Atlantic Ocean had warmed slightly.

More warm and salty subtropical surface water then can move northward into the eastern part of the North Atlantic basin.

As the waters curve north away from Antarctica due to the Coriolis effect, the warm water below the surface rises up to replace it.

It is apparently driven by the acceleration and slowing of the great ocean conveyor that carries warm surface water into the northern North Atlantic (Science, 1 July 2005, p. 41).

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.
