Not exact matches

The main feedbacks between climate and the ice sheet arise from changes in ice elevation, atmospheric and ocean circulation, and sea - ice distribution.

Climate and ocean - circulation changes that happened millions of years ago likely contributed to the differences in appearance between certain species of male and female seals.

There is a potential for both positive and negative feedbacks between the ocean and atmosphere, including changes in both the physics (e.g., circulation, stratification) and biology (e.g., export production, calcification) of the ocean.

What if the mixing between the oceans were drastically reduced due to changes in ocean circulation?

Everything else that might try to alter that base level simply results in atmospheric circulation changes (atmosphere includes oceans for this purpose) that adjust the rate of conversion between kinetic and potential energy so as to keep the base level of system energy content stable.

Here a simple biologically and physically - based model of sapflow potential is used to assess observed changes in sapflow across the Northeastern US from 1980 to 2006; document the correspondence between these observations and independent downscaled atmosphere ocean general circulation model (AOGCM) simulations of conditions during this period; and quantify changes in sapflow potential through 2100.

Climate and ocean - circulation changes that happened millions of years ago likely contributed to the differences in appearance between certain species of male and female seals.

There seems to be some sort of interaction between the air circulation and the ocean circulation which changes depending on whether the oceans are globally warming the air or globally cooling it.

«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.»»

«The situation is important for us, as the reduced temperature gradient between the equator and the North Pole is changing the circulation patterns and behaviours of the atmosphere and oceans, contributing to our direct experience of climate disruption.»

Between its Second and Third Assessment Reports, the Intergovernmental Panel on Climate Change elaborated long - term greenhouse gas emissions scenarios, in part to drive global ocean - atmosphere general circulation models, and ultimately to assess the urgency of action to prevent the risk of climatic cChange elaborated long - term greenhouse gas emissions scenarios, in part to drive global ocean - atmosphere general circulation models, and ultimately to assess the urgency of action to prevent the risk of climatic changechange.

This major change in ocean circulation, along with a climate that had already been slowly cooling for millions of years, may be what led to ice accumulation most of the time — but also to climatic instability, with flips every few thousand years or so between warm - and - wet and cool - and - dry.

As sub-surface oxygen concentrations in the ocean everywhere reflect a balance between supply through circulation and ventilation and consumption by respiratory processes, the absolute amount of oxygen in a given location is therefore very sensitive to changes in either process, more sensitive perhaps as other physical and chemical parameters.

The seasonal climate may relate to changes in the ocean circulation pattern prior to 4.6 Ma that resulted in an increased temperature and atmospheric pressure gradient between the east coast of North America and the Atlantic Ocean, but this climate phase seems to be only a temporary condition, as underlying and overlying sediment are both consistent with drier conditocean circulation pattern prior to 4.6 Ma that resulted in an increased temperature and atmospheric pressure gradient between the east coast of North America and the Atlantic Ocean, but this climate phase seems to be only a temporary condition, as underlying and overlying sediment are both consistent with drier conditOcean, but this climate phase seems to be only a temporary condition, as underlying and overlying sediment are both consistent with drier conditions.

The dust - induced thermal contrast changes between the Eurasian continent and the surrounding oceans are found to trigger or modulate a rapidly varying or unstable Asian winter monsoon circulation, with a feedback to reduce the dust emission from its sources (Zhang et al., 2002).

In addition, the authors provide compelling evidence of both the important coupling of ocean and atmosphere processes and the strong communication, of effects of climatic change, between the waters of the Northern and Southern hemisphere through global ocean circulation.»

Irrigation effects on climate may also be indirect, especially in monsoon regions where alteration of the thermal contrast between land and ocean may produce changes in monsoon circulation and the accompanying climatic variables.
