使用社区气候系统模式第3版（CCSM 3）全球气候模式，使用十年的CCSM 3数据计算了北美对流重要大气参数的年度和季节循环。有利于强对流天气的环境的时空分布的结果定性同意从NCAR/NCEP全球再分析的观测估计，虽然该模型低估了发生的频率恶劣的天气环境。这一结果表明了未来研究的可能性，旨在确定与全球气候变化相关的恶劣天气环境分布的可能变化。版权所有© 2007皇家气象学会
Annual and seasonal cycles of convectively important atmospheric parameters for North America have been computed using the Community Climate System Model version 3 (CCSM3) Global Climate Model using a decade of CCSM3 data. Results for the spatial and temporal distributions of environments conducive to severe convective weather qualitatively agree with observational estimates from NCAR/NCEP global reanalyses, although the model underestimates the frequency of occurrence of severe weather environments. This result demonstrates the possibility for future studies aimed at determining possible changes in the distribution of severe weather environments associated with global climate change.
