| 摘 要： | 运用REOF、9点二项式平滑滤波、累计距平、合成分析等方法，对山东省夏季极端高温的年代际变化、异常空间分布、时间演变特征、与赤道东太平洋海温异常的关系进行了较为详细的诊断分析，结果表明：从20世纪50年代到90年代，山东省夏季极端高温大部分地区是降低的，80年代降到最低，90年代有所回升，且在60年代末70年代初，大部分地区发生了一次由高向低的转折性变化；容易出现异常的区域为鲁西北、鲁西南、鲁南的临沂地区和山东半岛地区中部；与赤道东太平洋海温主要为负相关关系，前期为暖(冷)水期时，极端高温偏低(偏高)，高温日数减少(增多)。

| Abstract: | With REOF,9 point binomial filter,accumulative anomaly and composite analysis methods,the inter decadal variation,abnormal spatial features,and temporal evolution regularities of extreme high temperature in summer in Shandong Province and its relation with the East Pacific SSTA were studied in detail.Some results are obtained:from 1950s to 1990s,extreme high temperature in summer dropped in most parts of Shandong with the lowest in 1980s,then an increase in the 1990s, a transition from high to low from the end of 1960s to the early 1970s; anomaly occurs frequently in the northwest and southwest parts,Linyi and the peninsula of Shandong Province relatively.There is apparent negative correlation between Shandong and East Pacific SST extreme high temperatures. |
