Atmospheric general circulation model

Ocean-Atmosphere Interactions. To determine how the ocean responds to a C02-induced climate forcing, it will be necessary to develop a combined ocean and atmospheric general circulation model. It will take 10-20 years to develop a model with appropriate chemistry and biology to the level of confidence necessary to make valid projections. In the interim, two approaches can be pursued in parallel with this model development.

The global chemistry transport model (CTM) part is based on the CHASER model, which is based on CCSR/NIES/FRCGC atmospheric general circulation model (AGCM) version 5.7b. The basic features of the model have been already described in Sect. 2. The regional CTM part is based on WRF/Chem (Grell et al. 2005). The databases used are the following ...

The snow collected 33 km from Dumont d Urville was found to contain a ° Pb/ ° Pb ratio significantly lower than the background showing that it was polluted by base emissions, probably from leaded fuel which was purchased in Australia ( Pb/ ° Pb as low as 1.07). An alternative mechanism for lowering the ratio in the coastal snow was the transfer of Australian emissions through the atmosphere which was consistent with atmospheric general circulation models (54). Snow at the South Pole was also polluted by emissions from the Amundsen-Scott base, located only 7.3 km away.

Hydrodynamic models of the atmosphere on a grid or spectral resolution that determine the surface pressure and the vertical distributions of velocity, temperature, density, and water vapor as functions of time from the mass conservation and hydrostatic laws, the first law of thermodynamics, Newton s second law of motion, the equation of state, and the conservation law for water vapor. Abbreviated as GCM. Atmospheric general circulation models are abbreviated AGCM, while oceanic general circulation models are abbreviated OGCM. geomorphology...
