运用1960—2008年以来濮阳逐月和年平均最高、平均最低以及平均气温和相应的极端气温资料,借助线性分析和年代跃变分析的方法,研究其长期变化趋势和年际变化,结果表明:濮阳的夏季平均最高气温呈下降趋势、冬季最低气温和年平均气温呈现明显上升趋势,冬季增温主要在夜间,夏季降温主要在白天。全年的平均增温主要是由冬季夜间引起的。
The long-term trend and interannual variation of Puyang from 1960 to 2008 were analyzed by means of linear analysis and chronological analysis. The results show that: (1) Puyang has the highest average annual mean temperature, average minimum temperature, average temperature and corresponding extreme temperature data; The average summer maximum temperature of Puyang showed a downward trend. The minimum temperature and the annual average temperature in winter showed a clear upward trend. The winter temperature was mainly at night and the summer temperature was mainly during the day.
