摘要
文章基于德州市11个基本气象观测站1990-2020年逐日降水观测数据,采用线性倾向估计法和滑动平均法分析全市降水气候变化特征。结果表明:1990-2020年德州市暖季前期滑动平均降水量为1.98 mm,暖季中期滑动平均降水量为4.91 mm,暖季前期和中期整体以增加趋势为主,均通过了a=0.01的显著性水平检验。暖季后期滑动平均降水量为1.42 mm,整体以减少趋势为主,未通过a=0.01的显著性水平检验。
The article is based on daily precipitation observation data from 11 basic meteorological observation stations in Dezhou City from 1990 to 2020,The linear trend estimation method and the sliding average method are used to analyze the characteristics of precipitation climate change in the city.The results indicate that from 1990 to 2020,the sliding average precipitation in the early warm season of Dezhou City was 1.98 mm,and the sliding average precipitation in the middle warm season was 4.91 mm.Both the early and middle warm seasons showed an overall increasing trend,which passed the significance level test at a=0.01.The sliding average precipitation in the late warm season was 1.42 mm,showing an overall decreasing trend,which did not pass the significance level test at a=0.01.
