【摘要】 利用1951-2003年山东省夏季日最高气温资料,分析了山东夏季高温天气的时空分布和变化特征,以及高温异常的年代际振荡。得出:60-80年代,山东省各地夏季高温呈减少趋势,极端高温降低,90年代后有所回升,东部半岛地区回升明显;异常多高温年主要出现在50-60年代,异常少高温年集中在80年代,90年代中后期至今开始转为多高温时期;60年代末70年代初,山东夏季高温发生了一次显著的跃变过程。更多还原

【Abstract】 Base on the data of daily max-temperature in summer in Shandong province from 1951 to 2003,the inter-decadal spacial changes and oscillation features of high-temperature are analyzed in detail.Some results are obtained:From 1960s to 1980s,the estival hot days and extreme high-temperature dropped in all area of Shandong province,then increased in the 1990s with the obvious rise in Shandong peninsula;Most of hot summer occurred in the period from 1950s to 1960s,and cool summer concentrated in 1980s,and hot summer emerged again from the end of 1990s to this day;An evident transition for summer high-temperature in Shandong had happened about at the end of 1960s or at the early of 1970s.更多还原
