Sentences with phrase «mechanisms for ocean circulation»

Figuring out the mechanisms for ocean circulation modes depends on the evidence from paleoclimate, and on the stabilities seen via the great computer simulations.

Not exact matches

It's theoretically possible that some internal cycle in the ocean circulation could give Holocene temperature fluctuations as big as the LIA, but until one identifies such a mechanism, it's essentially impossible to say what the consequences would be for climate sensitivity.

«Changes in ocean circulation have been proposed as a trigger mechanism for the large coupled climate and carbon cycle perturbations at the Paleocene - Eocene Thermal Maximum (PETM, ca. 55 Ma).

It's theoretically possible that some internal cycle in the ocean circulation could give Holocene temperature fluctuations as big as the LIA, but until one identifies such a mechanism, it's essentially impossible to say what the consequences would be for climate sensitivity.

1) It seems to me that the key mechanism for any impact must be the changes that increased arctic ocean temperatures will impose on the atmospheric circulation feature known as the Polar Cell, and via this on the Ferrel cell which sits over the mid latitudes.

In the case of oceans the energy does penetrate the surface layers and is often carried away for eventual release elsewhere and at another time, depending on the ocean currents and other internal oceanic mechanisms such as the flow of the Thermohaline Circulation with a period of more than 800 years for a full circuit.

The atmosphere and oceans, through their general circulation, act as vast heat engines, compensating for this imbalance by providing nonradiative mechanisms for the transfer of heat from the Equator to the poles.

So, it is not surprising that those modellers who «need» to get warm surface waters to move into the depths of the oceans, and remain sequestered there for long periods of time, would turn to the physical mechanism of this vertical circulation system.

It includes results from a variety of different empirical approaches, including (1) time series analyses of the published temperature record; (2) examination of the response of the earth's outgoing radiation response to transient climate events; (3) calorimetric studies of the ocean - atmosphere system; (4) mechanisms for secular climate change arising from ocean circulation systems and astronomical influences; and (4) radiative and convective heat transfer in the oceans and atmosphere.

One of the most significant potential mechanisms is a shift in an ocean circulation pattern known as thermohaline circulation, which would have widespread consequences for Europe and the U.S. East Coast.

Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations in the climate forcing must be sufficiently small that the lower free troposphere warms evenly over land and ocean; second, the temperature response must not be large enough to change the global circulation to zeroth order; third, the temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.

The magnitude of the [geomagnetic - CO2] mechanism is small compared to the magnitude of the preponderant mechanisms driving the exchange of carbon between ocean and atmosphere, such as water temperature, biological pumping, overturning circulation... it would be preposterous to make the weakening Earth's magnetic field responsible for global warming.
