Sentences with phrase «as oceanic circulation»

Not exact matches

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.

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.

World weather patterns will also start to change, as a frigid Antarctic continent and the icy ocean currents that surround it play an important role in global atmospheric and oceanic circulation.

«As the circulation changed from decade to decade — 1980s to 1990s to 2000s — the model predicted a big dip in oceanic CO2 uptake during the 1990s, then a large increase in uptake during the 2000s,» DeVries explained.

Possible reasons include increased oceanic circulation leading to increased subduction of heat into the ocean, higher than normal levels of stratospheric aerosols due to volcanoes during the past decade, incorrect ozone levels used as input to the models, lower than expected solar output during the last few years, or poorly modeled cloud feedback effects.

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.

Washington, D.C. — Seawater circulation pumps hydrogen and boron into the oceanic plates that make up the seafloor, and some of this seawater remains trapped as the plates descend into the mantle at...

There could, for example, be SOC events reflected in ice sheet dynamics, as oceanic heat transfer destabilises the Antarctic circulation, leading to acelerated ice sheet destabilisation.

We need to be cognizant of everything from local - scale stable boundary layer micrometeorolgy and ocean unstable boundary layer turbulent processes to global oceanic and atmospheric circulation patterns such as the Arctic Oscillation and the Gulf Stream's seasonal evolution.

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.

In fact, they may do so more efficiently than more uniform temperature change; warming one hemisphere with respect to the other is an excellent way of pulling monsoonal circulations and oceanic ITCZs towards the warm hemisphere (the last few years have seen numerous studies of this response, relevant for ice ages and aerosol forcing as well as the response to high latitude internal variability; Chiang and Bitz, 2005 is one of the first to discuss this, in the ice age context; I'll try to return to this topic in a future post.)

Sea ice with its strong seasonal and interannual variability (Fig. 1) is a very critical component of the Arctic system that responds sensitively to changes in atmospheric circulation, incoming radiation, atmospheric and oceanic heat fluxes, as well as the hydrological cycle1, 2.

Such oceanic temperature as now subsists would probably be a historical inheritance from a long past state possibly at the end of the last ice age when it was reset by a combination of changed energy throughput from the sun plus the resistor effect of the oceans and air combined with the then state of the air circulation.

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.

One important feature that plays a role in these variations is the periodic change of atmospheric and oceanic circulation patterns in the tropical Pacific region, collectively known as El Niño — Southern Oscillation (ENSO) variation»

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.

• Even without major change in atmospheric and oceanic circulation, local shifts in centers of production and mixes of species in marine and fresh waters are expected as ecosystems are displaced geographically and changed internally.

As a consequence, it is likely that ice cover and oceanic circulation will be affected, and the wave climate will change.

If we can model paleoclimate as a function of landmass distribution and oceanic circulation, we have a huge leg up because they are obviously major factors affecting climate.

In turn I would link that to latitudinal shifts in the air circulation systems as combined solar and oceanic influences compete as described by me in my model and elsewhere.

No less astonishing is the prevalence of notion that the sluggish density - driven currents known as the «thermohaline circulation» are the main mechanism for oceanic heat redistribution.

As a geologist, I would like to see more modeling of oceanic circulation as the continents drift and mountain ranges come and gAs a geologist, I would like to see more modeling of oceanic circulation as the continents drift and mountain ranges come and gas the continents drift and mountain ranges come and go.

In my articles to date I have been unwilling to claim anything as grand as the creation of a new model of climate because until now I was unable to propose any solar mechanism that could result directly in global albedo changes without some other forcing agent or that could account for a direct solar cause of discontinuities in the temperature profile along the horizontal line of the oceanic thermohaline circulation.

Variability associated with these latter processes, generally referred to as natural long - term climate variability, arises primarily from changes in oceanic circulation.

1) Abstract «Such changes could have significant ramifications for global sea level, the ocean thermohaline circulation, native coastal communities, and commercial activities, as well as effects on the global surface energy and moisture budgets, atmospheric and oceanic circulations, and geosphere - biosphere feedbacks.

Thus as sea ice expands in a cooler climate, the high - latitude oceanic heat loss to the atmosphere is inhibited, the thermohaline circulation weakens, and the sinking regions move equatorward, leading to a shallower and weaker deep circulation.
