中文摘要:
      利用1954-2017年秦皇岛市气象站逐月平均气温资料,运用线性趋势、滑动平均等方法,对秦皇岛市气温变化特征进行分析。结果表明:近64 a秦皇岛平均气温呈上升趋势,趋势率为0.169℃/10 a;年平均最高气温和平均最低气温升温趋势率为0.153℃/10 a和0.156℃/10 a;不同季节升温不同,春季和冬季升温更为突出;月气温变化中3月升温趋势最大,2月次之;年极端最高气温变化范围在31.0~40.0℃,年极端最低气温变化范围-26~-8.6℃;秦皇岛观测站搬迁后气温比20世纪90年代明显下降。
英文摘要:
      Using the monthly mean temperature data of the meteorological observatory of Qinhuangdao from 1954 to 2017, the characteristics of temperature changes in Qinhuangdao City were analyzed using linear trend method, moving average method, and distance-equal mathematical statistics method. The results showed that the average temperature of Qinhuangdao in the recent 64 years is on the rise. The warming trend rate is 0.169℃/10 a; the average annual maximum temperature and mean minimum temperature increase trend rate is 0.153℃/10 a and 0.156℃/10 a; different temperature rises in different seasons, and the temperature rise is more prominent in spring and winter; the warming trend rate is 0.270℃/10 a and 0.263℃/10 a; the warming trend is greatest in March, followed by Februar; the extreme maximum temperature range of the year varies from 31.0℃ to 40.0℃, and the extreme minimum temperature ranges from -26℃ to -8.6℃; the temper-ature of Qinhuangdao observatory after the relocation has been significantly lower than that of the 1990s.
