Sentences with phrase «internal circulations of the oceans»

Not exact matches

Given the strength of the Hurst coefficients — something we all agree on — is it not possible that a large portion of the current warming trend is a product of internal climate variability, as mediated by complex dynamics of ocean circulation?

Discussion requires examination of how the freshwater injections alter the ocean circulation and internal ocean temperature.

Climate modeling groups have also been experimenting with ways to use the predictability of deeper ocean circulations (where internal variations can persist for up to a decade), but results have been mixed at best.

In attempting to substantiate this internal variability hypothesis, Spencer & Braswell (2011) assumed that the change in top of the atmosphere (TOA) energy flux due to cloud cover changes from 2000 to 2010 was twice as large as the heating of the climate system through ocean circulation.

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.

It should also be noted that observations related to sub-surface ocean circulation (oceanology), the prime source of internal variability, have only recently commenced on a consistent global scale.

The temperature of the troposphere is constantly being affected by variations in the rate of energy flow from the oceans driven by internal ocean variability, possibly caused by temperature fluctuations along the horizontal route of the thermohaline circulation and by variations in energy flow from the sun that affect the size (and thus density) of the atmosphere and the rate of energy loss to space.

Patterns of ocean and atmosphere circulation shift in response to internal climate dynamics and at a rapid pace determined by the dynamics of the system rather than any external factor.

The efficiency of each resistor varies independently because each has it's own set of internal circulations, the ocean cycles in the seas and the weather systems in the air.

While we have not evaluated all of the feedback mechanisms and internal and external forcing factors involved, we have shown evidence that the West Antarctic warming is consistent with the regional decline of sea ice in the ABS and with the atmospheric circulation trends over the Southern Oceans.

The existence of that cooler layer is evidence that the rate of evaporation is the primary influence on variability in the rate of ocean energy loss (apart from internal ocean circulation variability which is not relevant here) and it follows that more evaporation for the same rate of conduction and radiation (from a stable temperature differential) will send that cooler layer deeper and / or intensify the temperature differential between it and the ocean bulk below.

Some examples from energy balance model calculations indicate that: (1) solar variability has a near - global response, with the amplitude of response slightly larger over land; (2) volcanism has a proportionately larger amplitude of response over land than over ocean; and (3) the most oft - cited mode of internal variability, changes in the North Atlantic thermohaline circulation, has a hemispheric asymmetry in response.

The natural internal variability of the climate system arises from factors such as El Niño, fluctuations in the thermohaline circulation, and changes in ocean heat content.

Dr. Andreas Schmittner [responding to Dr. Paltridge's claim that the observed surface warming could have been caused by internal ocean fluctuations]: Could the Earth's observed surface warming of the last 50 years have been caused by ocean circulation?

This natural internal variability of surface temperature is an interaction between ocean circulations and winds.

Given the strength of the Hurst coefficients — something we all agree on — is it not possible that a large portion of the current warming trend is a product of internal climate variability, as mediated by complex dynamics of ocean circulation?

The medieval warm period and little ice age (whther they are local or global phenomena) are believed to be associated with thermohaline circulations in the atlantic; correct simulation of such long term internal oscillations in an ocean basin requires long term simulations for the ocean for which we don't really have any observational constraints.
