摘要
利用枣庄1958—2005年逐月平均气温序列,计算了其统计特征量、长期变化趋势、振荡周期和突变现象。结果表明:(1)枣庄气温具有明显的季风性大陆气候特征,总体呈现正态分布。(2)近50年来,枣庄气温总体上呈上升趋势;枣庄的年、季气温都存在突变现象且都在20世纪80年代末期到90年代初期;(3)各季节的气温都存在一定的显著震荡周期,有的还含有很强的超长期变化趋势。
Based on the monthly temperature data during 1958-2005 in Zaozhuang, the statistical characteristics are analyzed. Variation tendency, oscillation periodicity and sudden changing are studied. The results show： （ 1 ） The temperature had obvious climate characteristics of land monsoon and normal distributiom （2） The temperature trended to rise on the whole in the recent 50 years, there was sudden changing from the late 1980s to the early 1990s; （3） Some obvious Oscillation periodicity and extra long-range climatic variation characteristics are found from the seasonal temperature.
