辽阳市近50年气温变化特征研究

Research on Temperature Variation Features in Liaoyang during the Recent 50 Years

对辽阳市1960～2009年年平均气温、年平均最高气温、年平均最低气温、日平均气温稳定通过10℃起日、止日、起止日间日数及≥10℃积温进行分析,结果表明,近50年辽阳市年平均气温、年平均最高气温、年平均最低气温都在升高;日平均气温稳定通过10℃起日在提前、止日在推后、起止日间日数在延长,≥10℃积温在增大;气候变暖趋势明显。

This article analyzed annual average temperature,annual average highest temperature,annual average lowest temperature,and the starting date,the ending date,the interval days between starting date and ending date of the daily average temperature passed 10 ℃ stably as well as ≥10 ℃ accumulated temperature.The results indicated that annual average temperature,annual average highest temperature and annual average lowest temperature were rising;the starting date of the daily average temperature passed 10℃ stably were ahead,and the ending date were putting off,the interval days between starting date and ending date were delaying,≥10 ℃ accumulated temperature were increasing;the climate warming tendency was obvious.
