摘要
本文利用米易国家地面气象观测站1956—2019年观测资料,采用趋势分析、M-K突变检验方法研究米易高温变化特征。结果表明:年高温日数、年极端高温和年平均高温总体呈上升趋势,倾向率分别为3.3 d/10 a、0.25℃/10 a和0.08℃/10 a,与全球变暖结论一致。年高温日数、年极端高温2005—2019年均呈增加趋势,且在2006年左右有突变现象,年平均高温突变出现在2010年。
Based on the observation data of Miyi national surface meteorological station from 1956 to 2019,this paper uses trend analysis and M-K mutation test to study the variation characteristics of high temperature in Miyi.The results show that:the annual high temperature days,annual extreme high temperature and annual average high temperature show an overall upward trend,and the tendency rates are 3.3 d/10 a,0.25℃/10 a and 0.08℃/10 a respectively,which are consistent with the conclusion of global warming.Annual high temperature days and annual extreme high temperature showed an increasing trend from 2005 to 2019,and there was a sudden change around 2006.The annual average high temperature mutation occurred in 2010.
