1973—2019年黄石市气温变化特征分析

Characteristics Analysis of Temperature Changes from 1973 to 2019 in Huangshi

利用黄石市3个国家气象观测站1973—2019年的地面观测资料,采用线性倾向估计、M-K突变检验和异常分析等方法对黄石市气温变化特性进行分析。结果表明:黄石市年平均气温呈极显著波动上升趋势,四季平均气温呈较显著的上升趋势,其中春季增温最快,秋季、冬季次之,夏季最为缓慢;气温一般在20世纪80年代末期至20世纪90年代末期之间发生突变,之后气温呈现显著变暖趋势。黄石市近47年来没有出现异常偏冷年和异常偏暖年。

Based on the surface observation data from 1973 to 2019 in Huangshi,the variation characteristics of temperature were investigated using linear tendency analysis,M-K mutation test and anomalous analysis methods.The results show that the annual average temperature in Huangshi exhibited a very significant rising trend,and the average temperature in the four seasons showed a significant upward trend,in which the average temperature increased fastest in spring,followed by autumn,year and winter,and the summer was slowest.Generally,the mutations of temperatures occurred between the late 1980s and late 1990s,and then the climate was warming up significantly.There were no anomalous cold and warm year during the past 47 years in Huangshi.
