1971-2023年昌吉回族自治州区域性高温天气过程气候特征分析
Analysis of Climatic Characteristics of Regional High-Temperature Weather Process in Changji from 1971 to 2023
摘要
Abstract
Using daily maximum temperature data from May to September during 1971-2023 in Changji,this study analyzes the variation characteristics of summer maximum temperature,extreme maximum temperature,and high-temperature weather processes by applying climate trend analysis,Mann-Kendall trend test,and mutation detection.The results show that the average maximum temperature in summer over the past 53 years has shown an overall upward trend.The number of days with daily maximum temperatures of≥35℃in summer has increased linearly,with an abrupt increase in 2017 and a significant increasing trend after 2018.The onset of high-temperature weather has significantly advanced,while the end time has been slightly delayed.The frequency of high-temperature weather processes has increased significantly.Although the number of high-temperature weather processes of different intensities has also increased,only the increase in extremely high-temperature weather processes passed the significance test.Medium-to high-intensity high-temperature weather processes mainly occur in July.The cumulative number of high-temperature weather processes shows a significant increasing trend,most notably in the 2010s.The duration of high-temperature weather processes is closely related to their intensity,with stronger intensity process tending to last longer.关键词
