Abstract
Based on the observational data of Aletai area during 1962-2008,the tendency and the spatial-temporal variation of the four season＇s maximum and minimum temperature were obtained by methods of empirical orthogonal function and tendency analysis.The results showed that the escalation of increasing tendency was remarkable for the four season＇s temperature except the maximum temperature in spring.Both the maximum and minimum temperatures increased with the highest during winter.The area with the most obvious increasing temperature centralized in Jimunai and Fuyun,and the variability of Aletai was the lowest.The mean daily range of air temperature decreased significantly in the past 47 years.The decrease of daily range of air temperature probably associated with the asymmetrical variation of the maximum and minimum temperatures,and also significantly negatively correlated with the cloud cover.关键词
