By using the air temperature data from 1960 to 2004,the seasonal and inter-annual variations of temperature in DaLian are studied in this paper using methods of linear trend estimate,Morlet-wavelet analysis,and temperature trend coefficient analysis etc,with inter-annual and inter-decadal variations of winter temperature being emphatically studied.It is found that the warming trend is obvious in four seasons,and the warming rates in spring and winter are higher than those in other seasons.The winter temperature in DaLian showed a decreasing trend in 1960’s,but it began to rise distinctively in 1970’s,and the warming trend was very obvious in 1990’s.The variations of winter temperature in DaLian were consistent with those in whole China.
