Sentences with phrase «oceanic circulation»

• How are the mechanisms controlling sea ice extent and volume changing and how are they related to changes in atmospheric and oceanic circulation patterns in lower latitudes?

There is some evidence that oceanic circulation systems can back up and reverse - and this may then have released the stored CO2.

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

Climate change is caused by factors that include oceanic processes (such as oceanic circulation), biotic processes, variations in solar radiation received by Earth, plate tectonics and volcanic eruptions, and human - induced alterations of the natural world.

In this study, scientists compared the daily movement over the course of 13 to 350 days of ~ 40 juvenile loggerhead turtles tracked by satellite with oceanic circulation data from various sources off New Caledonia.

Once again, I will ask you to document your unspecific conjecture (with data or with a reference that confirms your statement) that «a discontinuity in the temperatures along the flow line of the thermohaline circulation or some other oceanic circulation» is the cause of the 1995/96 rise in tropical Pacific OHC.

Evolutionary multilocus analyses of 34,192 genome fragments reveal a fast radiation of rorquals at 10.5 to 7.5 million years ago coinciding with oceanic circulation shifts.

Changes in oceanic circulation directly alter the THC (Oke and England, 2004) and may explain recent patterns of observed temperature change at SH high latitudes described by Gille (2002).

For example: could different oceanic circulation rates change the oceanic CO2 sink / source behaviour, or could different atmospheric conditions change the mixing rates of atmospheric gases hence modify their affect on the solar forcing?

[17] A 1500 year cycle corresponding to the North Atlantic oceanic circulation may have widespread global distribution in the Late Holocene.

Sea ice extent over polar oceans is a major critical parameter for understanding and forecasting oceanic circulation and earth climate...

As well the freshwater from river systems affects oceanic circulation, which could exacerbate climate change.

For example a very large underwater volcanic event (eg the Gakkel Ridge eruptions in 1999) could quite feasibly disturb the regional oceanic circulation.

Thermohaline circulation, also called Global Ocean Conveyor or Great Ocean Conveyor Belt, the component of general oceanic circulation controlled by horizontal differences in temperature and salinity.

Because the oscillating pressure patterns are located above the ocean downwelling area near Greenland, the question is whether that pattern affects the downwelling and, in turn, the global oceanic circulation conveyor belt.

Their research, published in Nature Climate Change on June 29, is the first attempt to examine and document these changes in the air - sea heat exchange in the region — brought about by global warming — and to consider its possible impact on oceanic circulation, including the climatologically important Atlantic Meridional Overturning Circulation.

Could you please give a short explaination of what «thermohaline oceanic circulation» means?

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.

At that time, changes in atmospheric - oceanic circulation led to a stratification in the ocean with a cold layer at the surface and a warm layer below.

The poles are on the front lines of climate change — melting ice, thawing permafrost, warming temperatures — but they are also at the forefront of weather patterns, global oceanic circulation and the marine food chain.

Countless additional forces — melting ice sheets, shifts in precipitation, changes in atmospheric and oceanic circulation, to name a few — will influence the process as well.

Most likely, the bulge indicates a change in oceanic circulation.

All this modelling work, combined with in situ measurements (oceanographic campaigns recently carried out as part of the AMOP project) help improve our understanding of the interactions between biogeochemistry, atmospheric circulation and oceanic circulation.

Thanks to high - resolution models of the oceanic circulation and water oxygen content, IRD researchers and their partners have now quantified this ecosystem's sensitivity to various disturbances in the equatorial Pacific.
