摘要
利用1958—2017年东至县气象资料,采用线性趋势法分析近60年东至县各气象要素年、季、月际变化特征。结果表明,近60年东至县日照时数、平均气温、降水量和蒸发量月际呈抛物线变化趋势,6—8月较高(大)。日照时数全年、夏秋冬季和1月、6—10月显著减少,平均气温四季和1—7月、9—11月显著升高,降水量夏季和1月、7月显著增多,蒸发量全年及夏秋冬季和1—3月、6—12月显著减少。
Using the meteorological data from Dongzhi County during 1958-2017,the linear trend analysis was used to analyze the annual,seasonal and monthly variations of meteorological elements in Dongzhi County in the past 60 years.The results showed that the sunshine hours,average temperature,precipitation and evaporation in Dongzhi County in the past 60 years showed a parabolic trend from month to month,and were higher(larger)from June to August.Sunshine hours decreased significantly throughout the whole year,in summer,autumn,winter and from January to October.The average temperature increased significantly in the four seasons and from January to July and from September to November.The precipitation increased significantly in summer,January and July.Evaporation decreased significantly throughout the whole year and in summer,autumn,winter and from January to March and from June to December.
