利用阿勒泰地区7个气象站1962—2008年月均最高和最低气温、月均总云量和低云量实测资料,采用自然正交函数展开、趋势分析等方法,分析了该地区四季月均最高、最低气温的变化趋势及相应距平场的时空演变特征。研究表明：该地区除春季最高气温上升不明显外,春季最低气温及其余季节的最高、最低气温均呈显著的上升趋势,且最高、最低气温都在冬季上升幅度最大。四季最高、最低气温时空分布上自西向东大致呈高—低—高的分布,上升明显的中心区域集中在西部的吉木乃和东部的富蕴,变率较小的区域为阿勒泰。阿勒泰地区气温日较差近47 a呈显著减小趋势,日较差的减小与最高、最低气温的上升幅度不一致有关,也与云量呈显著负相关。
利用阿勒泰地區7箇氣象站1962—2008年月均最高和最低氣溫、月均總雲量和低雲量實測資料,採用自然正交函數展開、趨勢分析等方法,分析瞭該地區四季月均最高、最低氣溫的變化趨勢及相應距平場的時空縯變特徵。研究錶明：該地區除春季最高氣溫上升不明顯外,春季最低氣溫及其餘季節的最高、最低氣溫均呈顯著的上升趨勢,且最高、最低氣溫都在鼕季上升幅度最大。四季最高、最低氣溫時空分佈上自西嚮東大緻呈高—低—高的分佈,上升明顯的中心區域集中在西部的吉木迺和東部的富蘊,變率較小的區域為阿勒泰。阿勒泰地區氣溫日較差近47 a呈顯著減小趨勢,日較差的減小與最高、最低氣溫的上升幅度不一緻有關,也與雲量呈顯著負相關。

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.
