摘要
利用济南市1个国家级气象观测站和5个区域气象观测站2010—2014年逐小时气温观测资料,从分位数、相关性、一致性、正态性和周期性等方面,分析了城区、城郊以及不同海拔山区等不同地形背景下最高气温相关统计值的区域及季节差异性。结果表明:6个站点最高气温分位数统计值(高值、低值、中位数和四分位数)存在一定的站点间差异,其中不同海拔站点间差异较为显著,而相同海拔城区、城郊以及山区各测站之间的差异则相对较小,且这种站点间的区域差异在夏季表现得最为明显;城区间各站最高气温的相关性较强,而山区测站与其他各站间的相关性则相对较弱,这种相关性在春、秋季明显高于冬、夏季;站点间最高气温的频率分布以及周期振荡特征基本一致,各站最高气温在6—7月均存在一个显著的准单周振荡周期。
Based on the hourly air temperature data from one national base station and five regional automatic stations in Jinan during 2010—2014,the regional and seasonal differences in the related statistics of maximum air temperature under different terrain backgrounds（ including urban,suburban and mountainous areas with different elevations） are investigated from the aspects of quantile degree,correlation,consistency,normality and periodicity,etc. Results show that there are differences in quantile statistics（ including high value,low value,median and quartile） of maximum air temperature among six stations. The differences are significant among stations with different elevations,the differences are small among stations at the same altitude（ including urban,suburban and mountainous areas）,and the regional differences among stations are most obvious in summer. The correlation of maximum temperature between different stations in the urban areas is strong,and the correlation between mountain stations and other stations is weak. The correlation in spring and autumn is obviously higher than that in winter and summer. The frequency distribution and periodic oscillation characteristics of maximum temperature among stations are basically the same,and the maximum air temperature of each station has a significant quasi-seven-day periodic oscillation from June to July.
