山东气温极值年际分布和平/破纪录特征分析
Interannual distribution of extreme temperatures and record-equalling/breaking characteristics in Shandong
摘要
Abstract
Based on the daily temperature observations from 1960 to 2023 in Shandong,this study analyzes the interannual distribution of the extreme values of annual and monthly highest and lowest temperatures,as well the characteristics of record-equalling/breaking highest and lowest temperatures since 2000.The results are shown below.(1)The interannual variation of the extreme values of the lowest temperatures since 1960 has shown a significant upward trend.The upward trend of the extreme values of the monthly lowest temperatures is greater than that of the monthly highest temperatures,the upward trend of the lowest temperatures in the first half of the year is greater than that in the second half,and the upward trend of the extreme values of the monthly highest temperatures during the transition of seasons is more significant.(2)The annual highest temperature records mostly occur after 2000,with the most in June.The annual lowest temperature records mostly occur in the 1960s and 1970s,with the most in January.The number and amplitude of record-equalling/breaking highest temperatures since 2000 are generally higher and larger than those of the lowest temperatures.(3)The frequency and warming amplitude of the monthly record-equalling/breaking highest temperature events are higher and larger than those of the lowest temperature events,and especially during the transition of seasons when warm and cold air masses are more active,the frequency of record-equalling/breaking highest temperature events is higher.In November,the frequency and amplitude of the record-equalling/breaking lowest and highest temperature events are higher and larger.关键词
