摘要
利用我国 1 60站 1 951— 2 0 0 0年的月平均气温资料 ,在分析华北地区气温变化的季节—年际变化特征的基础上 ,重点分析了冬季的年际、年代际变化的时空特征。发现 :冬季气温在 50、60年代较低 ,70年代开始升高 ,80年代变化较为平缓 ,90年代增暖程度加大 ,50 a来有显著的增暖趋势 ,达 0 .2 7℃ /(1 0 a)。华北地区冬季气温的升高趋势与中国大部分地区是一致的 ,且是升高最明显的地区之一。
By use of the monthly mean air temperature data at 160 stations in China during 1951-2000 and based on the analysis of seasonal and interannual variations,the interannual and interdecadal variations of the air temperatures in North China are emphatically studied in this paper.It is found that the air temperatures in winter in North China were lower in 1950-1960's,began to rise in 1970's,changed smoothly in 1980's and got much warmer in 1990's.The warming trend was obvious in the recent 50 years and reached to a rate of 0.27℃/10-year.The trend in North China was similar with those in the most areas of China,however,its warming rate was the highest among them.
