Review the development
of atmospheric models for use in weather prediction and climate studies on all scales, including the diagnosis of shortcomings.
Continued scientific advances in understanding processes and their simulation
in atmospheric models are needed to understand how secondary influences will affect ozone.
The current generation of
global atmospheric models in use for climate studies around the world do some things remarkably well, as I've tried to argue in several earlier posts.
Review the development of
atmospheric models for use in weather prediction and climate studies on all scales, including the diagnosis of shortcomings.
It is our belief that «theory leads experiment» on climate change because all well - accepted
atmospheric models predict a temperature rise.
This should be an important warning for most current studies that use one -
dimensional atmospheric models: in other worlds they assume that every bit of the planet is like the rest.
Using a
3D atmospheric model, the researchers separated the effect of the chemicals from those of weather and volcanic emissions, which can also destroy ozone.
The findings are relevant to modern -
day atmospheric models and to an understanding of what a loss of sea ice means to both sea and land temperatures.
By considering the chemical changes, scientists can fine
tune atmospheric models, allowing them to better simulate the effects of environmental and regulatory changes.
I was able to impose this condition in a convection scheme and tested several variations in a single
column atmospheric model.
This study employed three newly developed global coupled climate models to study the impact of
horizontal atmospheric model resolution (tile size) on precipitation extremes.
The most commonly used method for representing lightning in global
atmospheric models generally predicts lightning increases in a warmer world.
The impact of sea surface temperature bias was further investigated by using uncoupled
atmospheric models with prescribed sea surface temperatures, and those 3 models each with differing complexity showed less severe double ITCZ bias than the ensemble of coupled models.
Promote the timely exchange of information, data and new knowledge
on atmospheric modelling through publications, workshops and meetings.
This year we received 14 June SIO submissions from dynamical models, of which 3 were from ice - ocean models forced by atmospheric reanalysis or other
atmospheric model output and 12 were from fully - coupled general circulation models.
That information can then be plugged
into atmospheric models to calculate cumulative emissions across larger areas, says Steve Wofsy, an atmospheric scientist at Harvard who is working on the project.
This contradicts a fundamental assumption of the current
atmospheric models which assume the atmosphere is only in local thermodynamic equilibrium.
They derived these data from NOAA's large - scale NAM (North American Mesoscale) model and a separate fine - scale
atmospheric model called RAMS.
The researchers
developed atmospheric models of the equilibrium chemistry for a brown dwarf at 250 degrees Kelvin and calculated the resulting spectra under different assumptions, including cloudy and cloud - free models.
This estimate was compared with results from an ocean model - data synthesis from ECMWF and a
leading atmospheric model - data synthesis produced in the US.
Comparison of the in - and out - of - storm spectra showed a prominent difference at 3 micron: Sromovsky and his team use
sophisticated atmospheric models to try to figure out what causes the difference in the spectra.
* * * The evidence to support the theory of anthropogenic, or human - caused, climate change has been mounting since the mid-1950s,
when atmospheric models predicted that growing levels of CO2 in the atmosphere would add to the natural «greenhouse effect» and lead to warming.
I knew the planet was problematic, perhaps too far on the outer edge of the habitable zone to be a realistic candidate, although this seems to depend on a variety of factors
including atmospheric modeling.
Combining state - of - the -
art atmospheric modeling with the latest measurement - based findings, researchers at Pacific Northwest National Laboratory found that toxic particles can last longer and travel much farther than previous models predicted.
For the July report, we received 14 June SIO submissions from dynamical models: 5 from ice - ocean models forced by atmospheric reanalysis or
other atmospheric model output (in green in Figure 3) and 9 from fully coupled general circulation models (in blue in Figure 3).
They also
ran atmospheric models that used observed global sea surface temperatures, Arctic sea ice conditions and atmospheric carbon dioxide concentrations in 2010 to assess whether such factors might have contributed to the heat wave.
Re-analysis data are results from
atmospheric models where observed data have been fed into the models and used to correct the simulation in order to try to get a best possible description of the real atmosphere.
On March 19, 2008, astronomers using the Hubble Space Telescope announced confirmation of the presence of water and the detection of more methane in the atmosphere of HD 189733's planet than would be predicted by
conventional atmospheric models for such a hot Jupiter - class planet (Hubble news release and videos; ESA news release and videos; and Swain et al, 2008).
