| Abstract: | Based on the daily temperature and precipitation data from 1951 to 2009 in Tianjin,a series of extreme climatic indices were calculated.Variation characters of 11 main extreme climatic indices were discussed.The results indicate that the variation trends of warm days and cold nights are contrary.Warm days increase and cold nights decrease significantly,and the variation amplitude of cold nights is larger than that of warm days from 1951 to 2009.Continuous warm stage and frost days increase,while continuous ... |
