摘要: 利用1951-2014年丹东地区气温和降水观测资料,对丹东地区平均气温、平均最高气温、平均最低气温和降水量的变化特征及变化趋势进行了分析。结果表明:近64 a丹东地区年平均气温呈显著的上升趋势,高于全国平均气温变化趋势,平均气温升高了约1.5℃;四季平均气温均呈上升的趋势,其中冬季增暖最明显;年平均最高气温和最低气温均呈上升的趋势,最低气温的增暖幅度明显大于最高气温,呈非对称增长;平均气温日较差呈下降趋势,冬季下降幅度最大。年降水量和年降水日数呈减少趋势,夏季、秋季、冬季降水量和降水日数呈减少趋势,其中夏季减少趋势明显,春季降水量和降水日数呈增加趋势。

Abstract: Based on observations of air temperature and precipitation in Dandong from 1951 to 2014,the evolution and characteristics of mean air temperature,mean maximum and minimum temperature,as well as precipitation amount and days,were analyzed in this study.The results show that the annual mean air temperature in Dandong from 1951 to 2014 increases obviously,by about 1.5℃,which is larger than the increasing rate averaged in China.Seasonal mean air temperature also increases in Dandong,with the largest increasing rate in winter.The increase of annual mean minimum temperature is greater than that of the annual mean maximum temperature,resulting in an asymmetric growth.The mean daily temperature difference decreases in all seasons,especially in winter.Both precipitation amount and days decrease in all seasons,particularly in summer,except in spring,resulting in a decrease of the annual mean precipitation.

Key words: Climate change, Air temperature, Precipitation
