| 摘 要： | 本文利用安徽省1971~2000年共30 a逐日平均气温、最高气温、最低气温的气候整编资料,选取气象观测环境完全符合相关规定(A类)和不完全符合相关规定(B类)两类代表站,分别建立了气温序列和两者的气温差值序列,并对气温序列的气候平均值和气温差值序列的气候趋势进行了分析。结果表明:气象观测环境的变化将影响气温序列。与A类台站相比,B类台站平均气温、最高气温和最低气温的气候平均值表现出一致偏高的特征,最低气温偏高最多;B类台站与A类台站平均气温、最高气温和最低气温的差值均有显著增大的趋势,平均气温差值的增大最为显著。

| Abstract: | Two groups of meteorological station were chosen in this paper.Group A were the stations where the environment around the stations entirely accord with related regulations and group B were not.Temperature and temperature difference between Group A and B series have been built up respectively by using climatological archiving data of Anhui Province,including daily mean,maximum and minimum temperatures,from 1971 to 2000.The normals of temperature series were also analyzed as well as the trend of temperature difference series.The result shows that the change of environment around meteorological observing stations has a significant effect on temperatures.Comparing with Group A,daily mean,maximum and minimum temperatures of Group B were higher,especially minimum temperature.It was also found that the differences of daily mean,maximum and minimum temperatures between Group A and B all have a remarkable increase trend.The trend of the daily mean temperature difference was the most remarkable. |
