近65年来吐鲁番市气温降水变化特征分析
Analysis on characteristics of temperature and precipitation change in Turpan city in recent 65 years
摘要
Abstract
Applying the methods of univariate linear regression, five-year moving average, anomaly analysis, cumulation anomaly statistic and signal-to-noise ratio test, the temperature and precipitation in the study area were analyzed. The results showed that the annual average temperature of Turpan increased at the rate of 0.41℃ ·(10 a)-1during the past 65 years, and the warming rate had accelerated since the 1980s;the increase rate of the annual average minimum temperature was greater than the annual average maximum temperature;the temperature difference between winter and summer decreased since the 1980s. There was a slight decrease in precipitation, with a decreasing rate of 0.48 mm·(10 a) -1. Seasonal changes of precipitation in different years were more obvious before the 21st century and more uniform in the past 17 years.关键词
