Abstract:With moving average, moving variance method, analysis of the temperature and precipitation of Dalian during 1951--2001 is made. It shows that the temperature of Dalian has the obvious warm tendency and the precipitation of Dalian has the decrease tendency. The changes of temperature are different in the four seasons. During the 50 years, the rise of temperature in winter is the most obvious, but the rise range of temperature in winter has been descent, and the range of temperature in summer has been increased. The climate of Dalian is becoming warmer and drier.In addition, the serious cold/warm winter events and the rainless stage and pluvial stage in Dalian are also studies.
Keywords:temperature precipitation climate change
