摘  要:
选用山东省80个代表站1961~2005年12、1、2月平均气温资料,利用统计学方法,探讨冬季气温的分布类型和变化特征。结果显示,气温变化存在3种基本空间分布类型,其中总体一致性暖(冷)型是主要分布类型,概率高于80%,其中严重/异常偏暖年份都发生在20世纪90年代以后,严重/异常偏冷年份则发生在80年代中期之前。另外两种类型东暖(冷)西暖(冷)型、南暖(冷)北暖(冷)型也偶有出现,但未达到异常标准。冬季及各月标准化气温第1主成分年际变化线性增温趋势显著,在不同年代存在2~6a的准周期变化。

摘  要:
Based on the monthly air temperature data from eighty meteorogical stations in Shandong Province from Dec to Feb during 1961~2005 and by statistic analysis,the yearly elemental distribution patterns and changing trends of the primary model were analyzed.The results show that there are 3 patterns in the normalized winter temperature and the concurrently warmer or colder type all over the province is the primary pattern,the probability reaches over 80%.The other patterns that the east is warmer(colder)and the west is colder(warmer) or the north is warmer(colder)and the north is colder(warmer)occur in some year,however the degree doesn' t reach abnormity standard by WMO,There are remarkable increasing trends in the variations of the first princi- pal component of normalized winter months temperature,and meanwhile there are 2~6a oscillation periods in different times.
