摘要
利用长年代气温资料讨论了重庆市年平均气温的多时间尺度特征 ,结果表明 :重庆市近几十年气温变化有明显的阶段性 ,但总的趋势是下降的 ,这与同期全球。
Based on MHF wavelet transform during the past long years in Chongqing the variations of temperature were analyzed. Some multi-scale and jump features of variations were discovered. Results show that the variations of temperature in Chongqing contain obvious staggered features. The variation tendency of temperature is descend. It is opposite to the tendency of the variations of temperature of the global, northern hemisphere and China.
