Not exact matches

For decades, research on climate variations in the Atlantic has focused almost exclusively on the role of ocean circulation as the main driver, specifically the Atlantic Meridional Overturning Circulation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large concirculation as the main driver, specifically the Atlantic Meridional Overturning Circulation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large conCirculation, which carries warm water north in the upper layers of the ocean and cold water south in lower layers like a large conveyor belt.

These storms result from the vertical circulation of water in the top layers, leaving large areas where air descends and becomes dry like the Sahara desert, and other areas where water rises to form the thunderstorms.

It * is * true too, that one can make numerical models, that when overlain with a large layer of fresh water that they reduce the so - called meridional overturning circulation.

We aren't talking about deep water here — most of the action is in the top 700m i.e. below the mixed layer, but not in the really slow deep circulations.

Extreme scenarios of climate change predict changes in the site of deep - water formation and a weakening of thermohaline circulation, which could result in changes in the oxygenation and biogeochemical cycles in the bottom layers of the deep Mediterranean Sea [148].

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.

00 meters), various exchange processes (well mixed layer turbulence, thermohaline circulation on 500 - 800 year timescale exposing deep water, biological pump aka «fish poo» moving carbon into deeper waters) that take considerably longer.

The waters that underlie the near - surface subtropical waters have freshened due to equatorward circulation of the freshened subpolar surface waters; in particular, the fresh intermediate water layer (at ~ 1,000 m) in the SH has freshened in both the Atlantic and Pacific Oceans.

Either this is a truism (the sun must be heating the ocean surface first) or it is meant to take into account the complex circulations that occur in the ocean, like the Gulf Stream's involvement in a vertical rise of waters from deep ocean layers in one region and sinking of the cooled surface waters as the stream reaches its northern limit.

Atlantic Meridional Overturning Circulation A major current in the Atlantic Ocean, characterized by a northward flow of warm, salty water in the upper layers of the Atlantic, and a southward flow of colder water in the deep Atlantic.

Because of their large size, tabular icebergs often travel great distances, and their movement can affect ocean circulation, the formation of bottom water (the dense layer of water at the very bottom of the ocean) and sea ice, and the productivity of life - forms in their path.

In the Atlantic Ocean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric Administration.

Water travels in the depths with the thermohaline circulation for centuries before it returns to the ocean surface layer.

This is seen observationally and in models as a weakening of the zonal circulation (Walker) in the tropics, and to a lesser extent, in the meridional (Hadley) since the rate of exchange of water parcels between the boundary layer and free atmosphere goes down.
