1981-2020年北京地区气温时空变化特征分析

Analysis of temporal and spatial variation characteristics of air temperature in Beijing from 1981 to 2020

文章通过收集1981-2020年北京地区20个国家级自动气象站的地面观测数据,并挑选其中具有代表性的6个平原站和5个山区站,采用线性拟合法和Mann-Kendall检验法分析全部站点、山区站及平原站的年平均气温、年平均最高气温、年平均最低气温及各个季节的年平均气温数据,从时间和空间两方面研究近40年北京地区的气温变化特征。为进一步研究北京地区气温变化规律提供依据。

By collecting the ground observation data of 20 national automatic meteorological stations in Beijing from 1981 to 2020,and selecting 6 representative plain observation stations and 5 mountain observation stations,the annual average temperature,annual average maximum temperature,annual average minimum temperature and various temperature of all observation stations,mountain observation stations and plain observation stations are analyzed,by linear fitting method and Mann Kendall method.The temporal and spatial variation characteristics of temperature in Beijing in the past nearly 40 years are studied to provide a basis for further research on the temperature change patterns in the Beijing area.
