1956-2005年中国暖冬和冬季温度变化

Areasonable warmer winter index(IwwI)in the framework of the three equiprobability categories(i.e.warmer,normal and colder categories)is proposed based on the winter temperature data observed at 565 stations in China during 1956-2005,where IwwI is defined as the ratio of the station number of warmer category over the total number of stations.The results suggest that the trend of IwwI was consistent with that of the winter temperature on decadal time scale,and their rates of change were 10%/10 a and 0.4℃/10 a,respectively.It is found that only 13 warmer winter events in total were detected by IwwI over the past 50 years,and 85% of them occurred after 1986.
