基于气候标准改变分析潍坊地区气候变化

Analysis of Climate Change in Weifang Based on Climate Standard Change

利用潍坊地区9个气象站的旬降水量和平均气温资料,比较1981—2010年和1991—2022年气候标准值的差异,并分析潍坊地区的气候变化地域特征。研究表明:潍坊地区降水量显著增加,气温也显著上升。潍坊地区1981—2010年和1991—2020年2个气候标准差异的变化显著,主要是由1981—1990年和2011—2020年2个气候态的差异导致的。气候标准的改变对统计分析气候变化和气象预报工作都有重大的影响。

Using the ten-day precipitation and average temperature data of 9 meteorological stations in Weifang area,the differences between the climatic standard values of 1981—2010 and 1991—2022 were compared,and the regional characteristics of climate change in Weifang area were analyzed.The research showed that the precipitation and temperature in Weifang area have increased significantly.The difference between the two climatic standards in Weifang from 1981 to 2010 and from 1991 to 2020 had changed significantly,which was mainly caused by the difference between the two climatic states from 1981 to 1990 and from 2011 to 2020.The change of climate standards had a significant impact on statistical analysis of climate change and weather forecasting.
