摘要
本文用中国科学院大气物理研究所的全球谱模式（Ｔ４２Ｌ９）和国家气象中心提供的１９９４年３月到１９９５年２月３６个例子（每月３个）的全球客观分析资料做了较系统的动力延伸（月）预报试验，检验了预报结果，分析了模式的气候漂移，并对预报结果进行了系统误差订正，结果表明预报评分有明显的季节变化，冬季较高，夏季较低。
With the IAP global spectral model (T42L9), a number of dynamical extended range forecast experiments are performed using initial fields from March, 1994 to February, 1995 provided by National Meteorological Centre of China. The forecast results show that the extended range forecast skill is of obvious seasonal variation, i.e. higher for the winter and lower for the Summer. The anomaly correlation coefficient of the dynamical extended range forecast for the 1～30 day mean 500 hPa geopotential height over the Northern Hemisphere is higher than that of the both persistence and climate forecast. In this paper we study the model climate drift and give the results corrected by systematic errors.
