上海市1951-2010年气温演变的结构性分析

The temperature changes in Shanghai during 1951-2010

使用上海气象站1951～2010年的逐日最高气温、逐日最低气温和逐日平均气温、相对湿度等数据，分析上海60年气温的变化，结果显示：（1）上海60年来气温演变与全球温暖化趋势一致，呈现干热变化趋势．（2）存在长短周期的冷暖变化，冬季增温明显，夏季增温趋缓．（3）气温增高的直接效果是适宜性、舒适性气温的持续时间增加，导致制冷时间增长，制热时间缩短，使人工能源的使用时间减少．

Based on the meteorological data during 1951- 2010, the change trends and characteristics of temperature in Shanghai in recent 60 years are analyzed. The results show that the temperature has increased remarkably in Shanghai, with the mosf obvious warming occurring in winter,and a dry trend. The hot days（-26 ℃ ） are decreased, the appropriate days （6-26 ℃） and the cold days（-6℃） are increased in Shanghai during 1951-2010. It should be noticed that the increase in minimum temperature is especially remarkable shows that the effect of climate warming on the minimum temperature is more obvious than others. These results cause energy consumption decrease.
