Characteristic Analysis of Temperature in Guiyang from 1951 to 2010
摘要
Abstract
Based on the time series of monthly and yearly temperature of Guiyang station from 1951 to 2010,by the moving average method,accumulated variance analysis and Mann-Kendall trend method,the changes of temperature were analyzed. The results showed that,during the past 60 years in Guiyang, the average temperature had the same slightly decreasing trend as the extreme maximum temperature,while the maximum temperature had a decreasing rate of 0. 14 ℃/10 a,the minimum temperature had no significant change,and the extreme minimum temperature had an increasing rate of 0. 28 ℃/10 a. Seasonally, the average and maximum temperatures in spring and summer demonstrated a more descending trend than those in autumn and winter. The minimum temperatures of four seasons do not change distinctly. The extreme maximum temperature in spring and winter had a more decreasing trend than that in summer and autumn. The extreme minimum temperature in autumn and winter showed a more upward trend than that in spring, contributing to a significant increasing trend of the annual extreme minimum temperature. The change of extreme temperature in Guiyang was becoming moderate,due to the remarkable upward trend of extreme minimum temperature and the slow decrease of the extreme maximum temperature.关键词
