1971-2018年迁西县气温变化特征

利用迁西县1971-2018年逐日气象数据以及趋势分析、突变检验等统计方法,分析了该区域气温的变化,结果表明：迁西县气温呈升高的趋势,年变化幅度略小于全省平均水平;气温的年代际变化在1990年代达到最大之后除春季外又有所回落,但变化幅度不大;迁西县的气温在上世纪80年代至90年代存在时间序列的突变过程,其中年气温、春季气温、冬季气温在上世纪突变上升趋势明显。该研究可以为当地合理利用热能资源提供理论参考。

The Characteristics of Temperature Change Ranged 1971~ 2018 in Qianxi County

Based on the daily weather data 1971-2018 in Qianxi County, adopting statistics method such as trend analysis and mutation test, this paper analyzed the temperature changes in this area. The results show that the temperature in Qianxi County illustrated an increased trend across these years, and the annual change was slightly lower than the provincial average level as a whole; the interdecadal change of it reached its maximum in the 1990s, but declined with not significant changes somewhat except the spring; the temperature in Qianxi County was a time series mutation process during the two decades of last century, when the annual temperature, spring temperature and winter temperature are obviously rising. According to the study, it is hoped to provide a theoretical reference for the usage of thermal energy resources rationally in local areas.
