Sentences with phrase «drive ocean surface currents»

Not exact matches

It is producing a «Submaran»: an unmanned device that can float on the surface of the ocean and also drive 200 meters under the water to monitor pipelines, currents, temperature or whatever a customer might want.

This is to be expected because the spin - up of the wind - driven ocean circulation speeds up the currents (Ekman transport) which carry heat out of the tropics in the near - surface layers toward the subtropical ocean gyres.

If the NAO were driving an ocean current that contains higher SST's and more saline surface water into the Arctic region, I suspect it would be a possible correlation that salinity may be playing a part in the Arctic ice loss.

It's always worth remembering that the other end of the AMOC involves two main factors: (1) vorticity - mixing of heat from surface waters into the deep abyssal ocean (which decreases density causing the Atlantic Deep Water to start rising above the colder Antarctic Bottom Water) and (2) the wind - driven upwelling around the Antarctic Circumpolar Current.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

For example, atmospheric carbon dioxide grew by approximately 30 % during the transition from the most recent cold glacial period, about 20,000 years ago, to the current warm interglacial period; the corresponding rate of decrease in surface ocean pH, driven by geological processes, was approximately 50 times slower than the current rate driven largely by fossil fuel burning.

Surface currents are largely wind - driven, although the rotation of the earth, the presence of continents, and the oceans» internal dynamics also have a strong influence.

In contrast to the wind - driven currents, the THC is not confined to surface waters but can be regarded as a big overturning of the world ocean, from top to bottom.

I do understand that the winds are driven by the uneven heating of the earth and, in turn, the winds effect surface currents, but the oceans of water, with it's peculiar properties, have an outsized effect.

15 Heat Transport in the Biosphere The unequal heating of Earth's surface drives winds and ocean currents transport heat throughout the biosphere Winds form because warm air tends to rise and cool air tends to sink air that is heated near the equator rises

After entering the Atlantic Ocean, the surface waters join the wind - driven currents in the Atlantic, becoming saltier by evaporation under the intense tropical sun.

Oceanic currents are largely driven by the surface wind stress; hence the large - scale atmospheric circulation is important to understanding the ocean circulation.

This empirical finding contradicts Spencer's hypothesis that cloud cover changes are driving global warming, but is consistent with our current understanding of the climate: ocean heat is exchanged with the atmosphere, which causes surface warming, which alters atmospheric circulation, which alters cloud cover, which impacts surface temperature.

Hamish Pritchard prepares us, «In most places in Antarctica, we can't explain the ice - shelf thinning through melting of snow at the surface, so it has to be driven by warm ocean currents melting them from below.

This wind distribution drives a system of surface currents in the uppermost 100 metres of the ocean.

wind and ocean surface currents are as much or possibly even more important than temperature in driving sea ice variability.

The induced current around the equator would drive the atmosphere and surface ocean currents simultaneously, although being lighter, the atmosphere might show a change before ocean currents.

Physically, it is difficult to see how ocean temperatures can cause a consistent pattern of winds high up into the atmosphere while we have a very good physical explanation of how the winds can drive the surface ocean currents and temperature.

They also drive the great surface ocean currents such as the Gulf Stream: which is why ideas that these currents could stop due to changes in water temperature is absurd.

In places surface water sinks — driving deep ocean currents — and in others it upwells.

Heat transfer into the deep oceans is pretty much all mechanically driven by «circulation» factors, so a cooling of the southern oceans due to changes in surface winds and currents would tend to change deep ocean uptake.

Currents that move through the upper ocean then dive down to depth may move some of the surface heat to the deeper waters, especially where the currents have dived not just from cooling water (hot water would tend to go up, cold water would tend to go down) but because it is driven in «conveyor» systems which may run counter to expectations of where water should go when considering only local conditions, and especially, if the water is dropping because of an increase in sCurrents that move through the upper ocean then dive down to depth may move some of the surface heat to the deeper waters, especially where the currents have dived not just from cooling water (hot water would tend to go up, cold water would tend to go down) but because it is driven in «conveyor» systems which may run counter to expectations of where water should go when considering only local conditions, and especially, if the water is dropping because of an increase in scurrents have dived not just from cooling water (hot water would tend to go up, cold water would tend to go down) but because it is driven in «conveyor» systems which may run counter to expectations of where water should go when considering only local conditions, and especially, if the water is dropping because of an increase in salinity.

The westerlies of middle latitudes and the trade winds of the tropics drive the most prominent features of ocean surface motion, large - scale roughly circular current systems elongated in the east - west direction known as gyres.
