«For example, the best global atmospheric models driven by specified sea surface temperatures can do a good job of simulating global temperature, winds and water vapor distributions.

Not exact matches

«Which of those is correct at this stage is unknown, but the droughts being driven by atmospheric greenhouse gas concentrations is in line with some of these global circulation models,» Lewis said.

In a study set to come out in Nature tomorrow, an international group of scientists reports that they simulated atmospheric behavior using several different models and used them to forecast anthropogenically driven changes in average annual rainfall at different latitudes from 1925 to 1999.

In this work, using a simple time - dependent 1D model, we demonstrate that radiative cloud feedback can drive spontaneous atmospheric variabilities in both temperature and cloud structures under conditions appropriate for brown dwarfs and directly imaged EGPs.

People who work in this field, called atmospheric scientists, use computers and math to model the properties of Earth's atmosphere that drive weather, climate and the movement of gases and pollutants through the air.

The advantage of such partially - coupled models is that they can be driven by past atmospheric conditions and the simulations match well the observed sea ice variability, which is strongly forced by the atmosphere.

And, the IPCC projection is probably too high because it was driven by a collection of climate models which new science indicates produce too much warming given a rise in atmospheric carbon dioxide levels.

This prediction failure has been due to the climate models assuming that minimum temperatures (nighttime temps) are driven by atmospheric CO2 levels, resulting in predicted minimum temperatures that are too high.

In contrast to Trenberth's 2015 lament that atmospheric circulation patterns are not robustly simulated by CO2 - driven climate models, predicting storm tracks and blocking are the most critical factors for providing early warnings.

The retrospective investigation consists of a model hindcast for more than a half century using «reality - based» atmospheric forcing to drive the model.

This result suggests that current projections of regional climate change may be questionable.This finding is also highly relevant to regional climate modelling studies where lower resolution global atmospheric models are often used as the driving model for high resolution regional models.

While the computer climate models exaggerate the warming effect of atmospheric carbon dioxide, they plausibly simulate that greater economic development driven by growing use of fossil fuels will add more carbon dioxide to the atmosphere.

This drives the evolution from atmospheric models to physical climate models to earth system models.

«What we've done is we've taken a model that was once tied to plant phenology and adapted it to be more tuned to the atmospheric component so that we can isolate the part that's driven by the climate system or is driven by the atmosphere.»

Most CM experiments based on RCPs will be driven by greenhouse gas concentrations (Hibbard et al. 2007).8 Furthermore, many Earth system models do not contain a full atmospheric chemistry model, and thus require exogenous inputs of three - dimensional distributions for reactive gases, oxidant fields, and aerosol loadings.

Therefore, a model run driven with atmospheric data from 2007, which is started from spring ice conditions in 2008 instead of 2007, leads to an even smaller ice extent.

As discussed in the article on natural cycles of ocean «acidification», and illustrated in the graph below by Martinez - Boti, over the past 15,000 years proxy data (thick lines) has determined surface pH has rarely been in equilibrium with expectations (green line) based on models driven by atmospheric CO2.

-- ... and thus it is only an assumption based on models (i.e., the idea that oceans are a net sink is based upon modeling, not observations) that the tiny changes in human emissions from year to year are driving the atmospheric CO2 concentration changes.

In other words, we obtained a site specific, tortuosity - depth relationship by adjusting diffusivity until the model reproduced the observed CO2 firn - air profile when driven by the independently derived atmospheric CO2 history (see Fig.
