Estimation of Precipitation Variation in River Basin Scale with Outputs from an Atmosphere-Ocean General Circulation Model called by MIROC

Global Climate and Ocean Circulation on an Aquaplanet Ocean–Atmosphere General Circulation Model

A low-resolution coupled ocean–atmosphere general circulation model (OAGCM) is used to study the characteristics of the large-scale ocean circulation and its climatic impacts in a series of global coupled aquaplanet experiments. Three configurations, designed to produce fundamentally different ocean circulation regimes, are considered. The first has no obstruction to zonal flow, the second cont...

The Atmosphere-Ocean General Circulation Model EMAC-MPIOM

The ECHAM/MESSy Atmospheric Chemistry (EMAC) model is coupled to the ocean general circulation model MPIOM using the Modular Earth Submodel System (MESSy) interface. MPIOM is operated as a MESSy submodel, thus the need of an external coupler is avoided. The coupling method is tested for different model configurations, proving to be very flexible in terms of parallel decomposition and very well ...

Simulation of modern and middle Cretaceous marine dO with an ocean-atmosphere general circulation model

[1] We have developed a coupled ocean-atmosphere general circulation model, the GENESIS-MOM model, with the ability to transport and fractionate water isotopes in the ocean and atmosphere. The model is used to predict modern and Cretaceous precipitation and seawater dO. The model reproduces the large-scale modernday isotopic distribution. In the zonal mean, the difference between simulated and ...

7.8 Interannual to Decadal Variabilities in the Pacific Basin in an Ocean General Circulation Model

The climate of the Last Glacial Maximum: Results from a coupled atmosphere-ocean general circulation model

Results from a coupled atmosphere-ocean general circulation model simulation of the Last Glacial Maximum reveal annual mean continental cooling between 48 and 78C over tropical landmasses, up to 268 of cooling over the Laurentide ice sheet, and a global mean temperature depression of 4.38C. The simulation incorporates glacial ice sheets, glacial land surface, reduced sea level, 21 ka orbital pa...
