摘要
依据实际资料,探讨了全球平均温度场演变序列的变率及其概率分布的变化规律,结果表明,仅仅随着平均温度的增加,其相应的时空概率分布变化已相当显著,何况在某些局部地区,其方差或其形状参数也有变动,因而形成极端气候事件频率增大的现象。
The variation features of long variability and the probability distributions for the global surface mean temperatures are researched by means of observed data under evidenced global warming rapidly. The results show that: (1) the real changes of the temporal & spatial frequency distribution have obviously made the probability of extreme values to be increase. (2) The change of variance or shape parameters of the distributions caurse the frequency increase of extreme climate events.
