摘  要:
利用南充市近54年气温资料,通过距平分析法、线性趋势分析法和30年滑动变异系数法分析气温变化趋势及特征,同时对极端冷暖天气事件进行了分析。结果表明,近54年来南充市年平均气温呈震荡上升趋势,四季气温除夏季外均表现为增暖趋势,秋季增温最为突出,对年平均气温的增温贡献最大;冬季气温波动明显高于其他季节和全年气温,不确定性较高,偏离平均值的年份最多,出现极端天气概率较大;近54年南充市出现了极端冷冬3次,热夏2次。

摘  要:
This paper analyzed 54- years temperature data of Nanchong,and the temperature variation and feature change were analyzed by using the anomaly analyzing,linear trend analyzing and the 30- year running temperature coefficients of variation,as well as,the extreme cold and warm weather events were analyzed and discussed. The results showed that the annual average temperature increased with a fluctuation trend,seasonal temperature showed a warming trend except for summer,and autumn warming increased prominently which contributed largest to the annual mean temperature increasing. By contrast,the fluctuation of mean temperature of winter were highest in the four season with a uncertain factors,maximum deviation from the mean of annual temperature,and a larger probability of extreme weather event. Three extreme cold winters and two extreme hot summers occurred in past 54 years.
