利用启东市1956～2010年逐日温度观测资料,分析了启东地区平均气温、极端气温、冷积温和热积温的变化趋势和特征;通过小波变化对其进行周期分析,发现50到80年代存在一个20到24年周期,90年代后存在12到16年的周期震荡,启东未来年平均气温有下降趋势,但总体仍处于偏暖时期。

Basing the daily temperature data in Qidong City from 1956-2010,the variation trends and characteristics of average temperature,extreme temperatures,cold accumulated temperature and heat accumulated temperature were analyzed.Using wavelet transform method,It shows that there is a 20-24 year cycle in the 1950-1980,12-16 year cycle shocks in 1990s.The annual average temperature has a downward trend in the coming years,which is still in the warm period.
