| 摘 要： | Systematic analysis of the records of air temperature for the last one hundred years has been madebased on the seven observation stations along the east coastal regions of China. The said air temperaturecan be basically divided into three alternate cold and warm stagts. It is noticeable that the air temper-ature in the northern China differs from that in the southern China. For example, the temperatures ofthe cold and warm stages north of Shanghai tend to rise while those south of Shanghai tend to fall, whichmight be related to the global northward movement of the climatic zone.
