1971~2020年泰安市夏季气候年代际变化
Climate Interdecadal Variabilities of Summer in Taian City during 1971~2020
摘要:
利用泰安五个大监站1971~2020年6~8月观测资料,分析了泰安1971年以来夏季不同气象要素(降水、气温、日照)的年代际变化特征。结果表明:泰安市夏季降水量呈现显著的年代际变化,变化趋势很大程度上取决于8月降水的变化,2017年之后很有可能已进入新一轮多雨期;近50年平均气温在波动中呈上升趋势,日照呈减少趋势,2007年后气温和日照时数增幅明显多于其他年代。
Abstract:
Based on the observation data between June and August from 1971 to 2020 from 5 meteorological stations in Taian City, the interdecadal variability of summer precipitation, temperature and sunshine duration in Taian City are analyzed. The results showed: The summer precipitation in Taian City showed significant interdecadal changes, and the change trend largely depended on the change of precipitation in August, and it was likely to enter a new rainy period after 2017; in recent 50 years, the average temperature showed an upward trend in fluctuation, while the sunshine showed a decreasing trend. After 2007, the increase of temperature and sunshine hours was obviously more than that of other years.
