| Abstract: | Based on air temperature data from 1951 to 2010,the characters of seasonal and annual mean air temperatures,the maximum and minimum air temperatures were analyzed by means of methods of climate trend coefficient and climate tendency and abrupt changes were checked by a Mann-Kendall method in Dalian.The results indicate that the seasonal and annual mean air temperatures are in increasing trends and the trends have slow down since 2000.Warming rate of annual mean air temperature is 0.33 ℃ per decade which is higher than that in China（0.22 ℃ per decade） and in the globe（0.13 ℃ per decade） in the recent 50 years.The rising mean air temperature mainly occurs in spring and winter.The warming amplitude of mean annual minimum air temperature is larger than that of mean annual maximum air temperatures.There are abrupt changes for annual and seasonal mean air temperature.The abrupt changes appear during 1987-1990.The difference of air temperature before and after the abrupt change is significant.There exist also abrupt changes for the mean annual and seasonal maximum and minimum air temperatures except the mean maximum temperature in autumn. |
