摘要: 本文根据1873—1990年上海的年、冬、夏平均气温资料,并利用1956—1990年其郊区气温资料,对城市热岛效应对气温的影响作了处理,重建了近118a的上海气温序列。在此基础上对上海的气温变化特征进行分析,并与同期的北半球气温变化作了比较。结果表明,上海的气温变化有其明显的阶段性、跃变性和周期性。近百余年上海气温变化的总体特征与北半球相似,呈缓慢变暖趋势,但具体的变化过程和幅度有差别,尤其近20多年来的变化与北半球不一致,没有明显的增温现象。

Abstract: Based on the data of annual, winter and summer mean temperature in Shanghai during the period of 1873-1990, the mean landsurface air temperature series for Shanghai for the last 118 year, period are reconstructed, in which the effect of urban heat island on temperature is di-smissed by using he tempperature data from -he suburbs of Shanghai during 1955-1990. The features of temperature long-term variations in Shanghai have been analyzed, and these features are compared with those in the northern hemisphere.
