摘要
利用连云港市7个气象台站47年（1960-2006年）的地面气温观测数据,采取Mann-Kendll、累计距平法和小波分析等方法,统计分析了连云港市地面气温的时空分布特征.结果表明,连云港市47年地面气温南高北低,平均差0.4℃;东高西低,相差约有0.7℃;平均值为14.1℃,有变暖的趋势,存在明显的18～22年周期.
We statistically analyze the spatial and temporal distribution features of the earth surface temperature in Lianyungang with Mann-Kendll,CA and wavelet analysis approaches and temperature data between 1960 and 2006 from seven weather stations.Results show that its average temperature gradully decreases from south to north in the past 47 years,the average difference of 0.4 ℃.The same temperature variety tendency also exhibits from east to west,the average difference of 0.7 ℃.Its annual average temperature is 14.1 ℃ and warming trend exists.The period of 18 to 22 years is quite obvious.
