| 摘 要： | 利用南京市1951-2005年的气温资料,研究了南京市近55年气温变化特征。结果表明:近55年南京市的平均气温显著上升,其中增暖幅度最大是春季,最小的是夏季。夏季,该地区的最低温度和平均温度都是上升趋势,但最高温度表现为下降的趋势,因此,对于南京地区,在温度总体呈现上升趋势的情况下,夏季有变凉的趋势;另外,年和各季日较差多表现出减小的趋势,只有春季的日较差有缓慢的上升趋势。

| Abstract: | Based on the meteorological data during 1951 and 2005,the change trends and characteristics of air temperature have been analyzed in Nanjing City. The results show that the air temperature has increased remarkably in Nanjing in recent 55 years,with the most obvious warming occurring in spring,and the most unobvious in summer. In summer,both the minimum temperature and mean temperature have increased,while the maximum temperature has decreased. So,the summer of Nanjing has become cool,although the temperatur... |
