«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric circulation.»»

That would change the air circulation patterns resulting in the observed wind effect on the ocean surfaces but would itself have been caused by changes in the rate of release or absorption of energy from the ocean surfaces.

«You may be getting global cooling of 1 - 2C on average, but that's entirely confined to certain regions and that would really upset weather patterns, ocean circulation and local biology.»

The most natural type of long term variability is in my view based on slowly varying changes in ocean circulation, which doesn't necessarily involve major transfer of heat from one place to another but influences cloudiness and other large scale weather patterns and through that the net energy flux of the Earth system.

Oceanographers also had reasons to believe that the pattern of North Atlantic Ocean circulation could change on a short timescale.

A change in ocean heat content can also alter patterns of ocean circulation, which can have far - reaching effects on global climate conditions, including changes to the outcome and pattern of meteorological events such as tropical storms, and also temperatures in the northern Atlantic region, which are strongly influenced by currents that may be substantially reduced with CO2 increase in the atmosphere.

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.

Falling back on the surface temperatures as the metric for the most societal relevant climate metric, even if its period of record is longer, is not a reason to focus on it, if it does not serve the purpose of telling us if humans are significantly altering these circulation patterns, and thus the weather and ocean conditions that matter the most in terms of the impacts on water resources, food, energy, human health and ecosystem function.

Identify the impacts of a changing climate on sea ice loss; sea ice loss on patterns of atmospheric circulation and precipitation; oceanic circulation both within and beyond the Arctic, including the meridional overturning circulation in the Atlantic Ocean; and weather patterns in middle latitudes.

Advance research on the interactions between arctic sea ice and global physical systems such snow cover extent, ocean and atmospheric circulation patterns, and mid-latitude effects.

While on first thought this might seem undesirable because we are looking for a global number, it might make sense to separate them due to the large difference in land / ocean ratio and the fact that atmospheric circulation patterns isolate them WRT shorter term changes.

Gyre - Basin - scale ocean horizontal circulation pattern with slow flow circulating around the ocean basin, closed by a strong and narrow (100 - 200 km wide) boundary current on the western side.

Modes or patterns of climate variability - Natural variability of the climate system, in particular on seasonal and longer time scales, predominantly occurs with preferred spatial patterns and time scales, through the dynamical characteristics of the atmospheric circulation and through interactions with the land and ocean surfaces.
