Abstract
Based on the daily average temperature data from meteorological stations in 6 counties in Lu’an City during 1981-2015, changing characteristics of the beginning and ending dates, continuous days, and accumulated temperature of ≥10 and≥20 ℃ were analyzed by using linear climate tendency analysis and M-K nonparametric mutation analysis.The results showed that in Lu’ an City during recent 35 years, the beginning dates of ≥10 and ≥20 ℃ were 2.2 and 3.1 d/10 a earlier respectively, and their abrupt changes occurred in 1997; the ending dates were 1.4 and 0.9 d/10 a later respectively, but the ending dates had no significant abrupt change.The continuous days of ≥10 and≥20 ℃ increased significantly by 3.6 and 4.0 d/10 a respectively, and the abrupt changes happened around 1997 and 1994 respectively. The accumulated temperature of≥10 and≥20 ℃also increased significantly by 126.7 and 116.0 ℃/10 a respectively, and the abrupt chan-ges appeared around 1994.关键词
