Circulation Statistics from Seasonal and Perpetual January and July Simulations with the NCAR (National Center for Atmospheric Research) Community Climate Model (CCM1):R15

摘要

Horizontal maps and meridional cross sections of selected circulation statistics are presented for 15-year seasonal and 1200-day perpetual January and July simulations with the 12-layer R15 version of the NCAR Community Climate Model (CCM1). These circulation statistics provide prospective model users with a brief, concise summary of the climate produced by the configuration of the model. The statistics are computed for the 90-day December, January, February and June, July, August periods of the 15 years of the seasonal runs. For the perpetual simulations they are computed for 90-day periods separated by 60 days to ensure reasonable independence, yielding eight samples. The statistics are presented in such a way as to easily allow direct comparison with the model's predecessor (CCMOB). They also allow direct comparison between the perpetual and seasonal simulations.
