Abstract
[Objective] The research aimed to study the variation characteristics of winter temperature in Jinan in recent 60 years. [ Method] Based on winter monthly average, maximum and minimum temperatures in the ground observation station of Jinan during 1951 -2010, by u-sing the linear trend, 5-year moving average and anomaly, the variation characteristics of winter average, maximum and minimum temperatures in Jinan in recent 60 years were analyzed. The historical evolution trend and decadal variation characteristics were discussed. [ Result] Winter average, maximum and minimum temperatures in Jinan in recent 60 years all presented the slow fluctuation rising trend. The rising trend was obvious. Especially the increase range of minimum temperature was the maximum. It illustrated that the variation of minimum temperature was more sensitive than that of maximum temperature, and the climatic warming in winter was mainly from the contribution of minimum temperature rising. Seen from the decadal variation, cold winter mainly appeared before the 1970s. Then, it presented the obvious decrease trend. Conversely, warm winter presented the increase trend after the 1970s. Warm winter phenomenon decreased after 2000. Winter temperature presented the stepped warming trend during 1950s - 1990s. Winter average temperature presented the jump warming trend after the 1990s. The temperature presented the downward trend when entering into the 21st century. But winter temperature presented the rising trend as a whole. The population growth in Jinan made that urbanization process accelerated, and urban heat island effect aggravated. It was one of important factors for climate warming in Jinan. [ Conclusion] The research provided the theoretical basis for understanding the long-term variation trend of climate in Jinan area and if it was consistent with the background of global climatic warming.关键词
