Experiments carried out in the OU Mars Simulation Chamber — specialised equipment, which is able to simulate the atmospheric conditions on Mars — reveal that Mars» thin atmosphere (about 7 mbar — compared to 1,000 mbar on Earth) combined with periods of relatively warm surface temperatures causes water flowing on the surface to violently boil.

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.

So, if each underwater artic volcano emitted 1 km3 a week (a rather large average flow) and did it for a year (about 52 weeks) you would need about 620 very active and extremely powerful volcanoes in order to warm the artic ocean by just 1 C (and that ignores surface cooling, in / out water flows and time rates that would require even more volcanoes.)

It is a narrow (85 km) and very shallow (55 m) strait with a continuous northward flow (1 m / s) that siphons warm surface water from the Pacific.

eadler2 January 10, 2015 at 5:54 pm ... When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

When ocean surface temperatures cool, due to a La Nina, the warmer surface water is mixed deeper into the ocean and cooler ocean water flows along the surface of the Pacific.

The soil thaws, the surface collapses, lakes form, water flows, land surfaces erode which in turn releases more carbon dioxide to create more warming, to make the tundra even more vulnerable to spring thaw, and of course to accelerated warming.

The relatively warm water flowing through the glacier also carries surface heat deep inside the ice sheet far faster than it would otherwise penetrate by simple conduction.

The results suggest that warm Atlantic water never ceased to flow into the Nordic seas during the glacial period; inflow at the surface during the Holocene and warm interstadials changed to subsurface and intermediate inflow during cold stadials.

The warm intruding Atlantic water is saltier and denser and flows between 100 and 900 meters below the surface.

El Ni o an irregular variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south; does not usually extend farther than a few degrees south of the Equator, but occasionally it does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising sea - surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing

«once you remove a large heat flow, for example by letting all the water boil away, the surface heats up» So, Eli is saying, if absorptive material is added (to the atmosphere) the surface cools; if absorptive material is removed, the surface warms.

Much of it is forced down and it flows back to the east at 200 metres depth and when the warm water surfaces at the Galapogos Islands in 9 months (replaceing the water which is flowing east - west at the surface), it starts to slow down the Trade Winds because of the convection effect.

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.

Although the flows are vastly more complex than I make out — the vast area of warmer surface water warms the atmosphere.

Warm water flows between Australia and Indonesia influencing sea surface temperature in the Indian Ocean and rainfall in Africa and Australia.

By 1961 the oceanographer Henry Stommel was beginning to worry that these warming currents might stop flowing if too much fresh water was added to the surface of the northern seas.

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 water warms the air, then cools, sinks, and returns towards the equator as a deep flow.»

It is not «conduction» but exchange of radiation; if you keep your hands parallel at a distance of some cm the right hand does not (radiatively) «warm» the left hand or vice versa albeit at 33 °C skin temperature they exchange some hundreds of W / m ² (about 500 W / m ²) The solar radiation reaching the surface (for 71 % of the surface, the oceans) is lost by evaporation (or evapotranspiration of the vegetation), plus some convection (20 W / ²) and some radiation reaching the cosmos directly through the window 8µm to 12 µm (about 20 W / m ² «global» average); only the radiative heat flow surface to air (absorbed by the air) is negligible (plus or minus); the non radiative (latent heat, sensible heat) are transferred for surface to air and compensate for a part of the heat lost to the cosmos by the upper layer of the water vapour displayed on figure 6 - C.

Yet an increase in the surface area of crevasses can accelerate the flow because it means more of the ice's interior is exposed to warming by surface melt water.

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.
