阿勒泰地区气温日较差的气候变化特征OACSTPCD
Climatic characters of diurnal temperature range in Altay region
利用线性趋势法对1961—2008年阿勒泰地区7个气象站点气温日较差进行趋势研究,并根据各因子趋势值,应用相关统计法分析了影响气温日较差呈减小趋势的因子。结果表明：阿勒泰地区四季日较差呈显著减小趋势,其中冬季最显著,秋季变化最弱。各季节最低气温上升趋势最明显,而最高气温上升趋势较弱。阿勒泰地区月平均气温日较差相关性最强的因子是日照时数,呈正相关;其次分别为总云量、降水量和水汽压,均呈负相关。年气温日较差与降水量和水汽压相关性最大。
The variation trend of the diurnal temperature range（DTR） and its impacting factors were analyzed using methods of a liner trend and a statistic correlation analysis based on temperature data at 7 weather stations from 1961 to 2008 in Altay region.The results indicated that the seasonal DTR is in a significant decreasing trend,especially in winter.Variation of autumn DTR is small.The increasing trends of seasonal minimum temperature are the most significant,…查看全部>>
