TL;DR: In this paper, a global three-dimensional model that can treat transportation of various species of aerosols in the atmosphere is developed using a framework of an atmospheric general circulation model (AGCM).

TL;DR: In this paper, the authors examined the origin and transport processes of water in the atmosphere-land system by using an atmospheric general circulation model, and the results indicated that a significant portion of the precipitating water in inland Eurasia in the summer was supplied by evaporation from the Atlantic Ocean in the previous winter and is transported eastward with a few recycling cycles between the atmosphere and the continental surface.

TL;DR: An accelerated scheme for cloud overlap is developed and tested and the resultant accuracy of the scheme is better than that of the line-by-line calculation method.

TL;DR: In this article, the broad climatological features associated with the Asian monsoon circulation, including its mean state and intraseasonal and interannual variability over the Indian subcontinent, as simulated in the CCSR/NIES coupled A-O GCM in its control experiment are presented.

TL;DR: In this paper, an atmospheric general circulation model (AGCM) is forced with a prescribed SST dipole anomaly in the tropical Atlantic to investigate the cause of cross-equatorial SST gradient (CESG) variability and its teleconnection to the extratropics.
