Sentences with phrase «include ocean circulation models»

Not exact matches

Salinity of the surface waters can be influenced by the amount of river water flowing into the oceans, yet no computer models of ancient ocean circulation had included this variable.

Some of the variables controlling the models are not all that well known,» he adds, including forces such as winds, ocean circulation, and how icebergs calve.

Our study compares climate models that include ocean circulation (top right) with climate models that have no ocean circulation (bottom right).

I'd love to know what they did take into account in attempting to model that period — must include astronomical location, sun's behavior, best estimates about a lot of different conditions — where the continents were, what the ocean circulation was doing, whether there had been a recent geological period that laid down a lot of methane hydrates available to be tipped by Pliocene warming into bubbling out rapidly.

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.

The periods considered were mainly the Pleistocene ice age cycles, the LGM and the Pliocene, but Paul Valdes provided some interesting modeling that also included the Oligocene, the Turonian, the Maastrichtian and Eocene, indicating the importance of the base continental configuration, ice sheet position, and ocean circulation for sensitivity.

«GCM — General Circulation Model (sometimes Global Climate Model) which includes the physics of the atmosphere and often the ocean, sea ice and land surface as well.»

Although previous studies have offered a general global overview of water circulation between the oceans and land, this traditional two - region model does not take into account the considerable precipitation that occurs over tropical coastal regions, including the Indonesian maritime continent, the Indian subcontinent, and the Bay of Bengal.

The ensemble and seasonal forecast systems use a coupled atmosphere - ocean model, which includes a simulation of the general circulation of the ocean and the associated coupled feedback processes that exist.

But certainly models with such a grand name as «General Circulation Model», would include average diurnal atmospheric circulation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the deCirculation Model», would include average diurnal atmospheric circulation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the decirculation patterns in tropics, and diurnal and seasonal patterns at latitudes outside the tropics, as well as heat transfer to the deeper ocean.

The fact that Wahl and Ammann (2006) admit that the results of the MBH methodology does not coincide with the results of other methods such as borehole methods and atmospheric - ocean general circulation models and that Wahl and Ammann adjust the MBH methodology to include the PC4 bristlecone / foxtail pine effects are significant reasons we believe that the Wahl and Amman paper does not convincingly demonstrate the validity of the MBH methodology.

The response of atmospheric CO2 and climate to the reconstructed variability in solar irradiance and radiative forcing by volcanoes over the last millennium is examined by applying a coupled physical — biogeochemical climate model that includes the Lund - Potsdam - Jena dynamic global vegetation model (LPJ - DGVM) and a simplified analogue of a coupled atmosphere — ocean general circulation model.

These studies include regional surveys, modeling ocean circulation and identifying shipwrecks.

The answer is not likely in line by line radiative transfer models but in ocean dynamics including equator to pole circulations.

The chemistry - climate models used for the 2006 Ozone Assessment, predict that the Antarctic ozone hole will achieve full recovery in the second half of this century, and that this may have profound impacts on the surface winds and, likely, on other aspects of the Earth's climate, including surface temperatures, locations of storm tracks, extent of dry zones, amount of sea ice, and ocean circulation.

When a full - depth ocean model is used, something intriguing happens: the loss of Arctic sea ice triggers a far - flung response that mimics climate change itself, including a slowdown of the Atlantic Meridional Overturning Circulation (AMOC), a build - up of heat in the tropical oceans over several decades, and a warming of the atmosphere a few miles above the tropics.
