Abstract: The characteristics of variability of monthly average global and hemispheric air temperature in recent 150 years were analyzed. The correlations of the variability and the air temperature series were also discussed.

Key words: climatic variability, standard deviation, scales

摘要： 基于对变率的标准差估计，分析了近百年来全球及南北半球月平均温度的一阶变率和二阶变率，讨论了一阶、二阶变率与原序列之间的关系。
