摘要
利用1971—2010年烟台市气温相关资料,分析了烟台市近40年的气温变化特征。分析结果表明,近40年烟台市的年平均气温、年平均最高气温、年平均最低气温均呈明显上升趋势。年平均气温中增温幅度最大的是春季,其次是冬季,年平均气温气候倾斜率为0.39℃/10年。年平均气温、年平均最高气温以1988年为分界点,年平均最低气温的分界点为1989年,其后的年份增温明显。与近40年的气温变化趋势相比较,近10年中,年平均气温在变化中呈下降趋势,年平均最低气温呈上升趋势,年平均最高气温与近40年的变化趋势一致。
Characteristics of temperautre change in recent 40 years in Yantai City were analyzed by using temperature data from 1971 to 2010. The results showed that the average temperature, the maximum temperature and the minimum temperature increased significantly.Among the increases of average temperature, amplification of spring was the largest, amplification of winter was the second,with the average variation of 0.39 ℃ during 10 years.Year 1988,as was the point of the average temperature and the maximum temperature,while Year 1989 was the point of the minimum temperature, and the temperature increased significantly in later years.Compared with variation trend of temperature of recent 40 years, the average temperature decreased in recent 10 years, while the average minimum temperature increased, and average maximum temperature showed the same trend with the recent 40 years.
