The weakening of the Walker circulation arises in these models from processes that are fundamentally different from those of El Nià ± o — and is present in both mixed - layer and full - ocean coupled models, so is not dependent on the models» ability to represent Kelvin waves (by the way, most of the IPCC - AR4 models have sufficient oceanic resolution to represent Kelvin waves and the physics behind them is quite simple — so of all the model deficiencies to focus on this one seems a little odd).

part of the utility is that Charney sensitivity, using only relatively rapid feedbacks, describes the climate response to an externally imposed forcing change on a particular timescale related to the heat capacity of the system (if the feedbacks were sufficiniently rapid and the heat capacity independent of time scale (it's not largely because of oceanic circulation), an imbalance would exponentially decay on the time scale of heat capacity * Charney equilibrium climate sensitivity.

Changes in oceanic circulation in the North Atlantic have influence on a planetary level by affecting, in particular, the water cycle.

(2010) presents evidence of the unique impacts of Central Pacific (CPAC) El Niño events (i.e., El Niño episodes when the warmest waters are located in the central tropical Pacific) on the Northern Hemisphere atmospheric and oceanic circulation on interannual and decadal time scales.

24) Climate in any given location is simply a product of the current balance in the troposphere between the solar and oceanic effects on the positions and intensities of all the global air circulation systems

Once the sign of the solar effect on the stratosphere is reversed it becomes possible to propose a system of climate change arising simply from the latitudinal shifting of the air circulation systems in response to competing forces from variable oceanic and solar cycles.

This Section places particular emphasis on current knowledge of past changes in key climate variables: temperature, precipitation and atmospheric moisture, snow cover, extent of land and sea ice, sea level, patterns in atmospheric and oceanic circulation, extreme weather and climate events, and overall features of the climate variability.

While the circulation of the Atlantic Ocean has a complex three - dimensional spatial structure, the zonally integrated flow in the basin, referred to as the Atlantic Meridional Overturning Circulation (AMOC), is largely responsible for the net northward oceanic heat transport on climate - relevant circulation of the Atlantic Ocean has a complex three - dimensional spatial structure, the zonally integrated flow in the basin, referred to as the Atlantic Meridional Overturning Circulation (AMOC), is largely responsible for the net northward oceanic heat transport on climate - relevant Circulation (AMOC), is largely responsible for the net northward oceanic heat transport on climate - relevant timescales.

The problems we are working on range from basic studies of circulation patterns of water in the ocean and groundwater flow systems to the variability of the oceanic circulation under natural and anthropogenically forced conditions or the transport and transformation of contaminants.

Climate threshold - The point at which external forcing of the climate system, such as the increasing atmospheric concentration of heat - trapping gases (greenhouse gas es), triggers a significant climatic or environmental event which is considered unalterable, or recoverable only on very long time - scales, such as widespread bleaching of corals or a collapse of oceanic circulation systems.

Any variability in oceanic circulation could have strong effects on local, and hence average temperature, even with a fixed energy budget.

However, with the new evidence that changes in atmospheric and thus oceanic circulation may have obscured changes in sea level (http://environment.newscientist.com/article/dn12547-flatter-oceans-may-have-caused-1920s-sea-rise.html), is there any evidence that the previously apparently static sea levels caused groups to self - censor data on ice sheet melting?
