德化县地表温度变化及影响因子分析

Analysis of Surface temperature change and its influencing factors in Dehua County

利用德化县国家气象站1980~2018年观测资料,采用一元线性回归、散点图和相关性分析,对德化39年地表温度变化及其影响因子分析。结果表明:德化县地表温度年序列呈上升趋势,速率为0.36℃/10a,且上升趋势显著。通过与同期云量、气温、降水量、风速、相对湿度和日照六个气象因子对比分析,认为地表温度上升主要是由气温、日照、秋季风速共同作用引起,以气温相关性最好。

Based on the observation data of Dehua County National Meteorological Station from 1980 to 2018,the variation of surface temperature and its influencing factors in Dehua for 39 years were analyzed by univariate linear regression,scatter plot and correlation analysis.The results show that the annual sequence of surface temperature in Dehua County shows an upward trend,the rate is 0.36℃/10 a,and the upward trend is significant.Compared with the six meteorological factors of cloud cover,air temperature,precipitation,wind speed,relative humidity and sunshine in the same period,it is considered that the increase of surface temperature is mainly caused by the combined action of air temperature,sunshine and autumn wind speed,and the correlation between air temperature is the best.
