摘要
基于南城站2003-2011年地面气象观测资料,对相对湿度人工和自动观测记录进行对比分析,南城站逐月相对湿度人工观测值与自动观测的结果比较接近,97.25%的月份人工观测月平均相对湿度大于自动观测值。南城站75.49%的时次人工观测相对湿度大于自动观测相对湿度,逐时相对湿度人工与自动观测值差值主要集中在-5%~10%之间。以能见度定时观测记录为依据,对按照人工与自动观测相对湿度统计的霾、轻雾、雾出现时数进行分析,结果表明:相对湿度进行自动观测以后,相对湿度系统偏低,造成南城站霾的观测记录明显增多,轻雾的观测记录减少,对雾的观测记录影响不显著。
Based on the surface meteorological observation data of Nancheng station from 2003 to 2011, the relative humidity manual and automatic observation records are compared and analyzed, and the monthly relative humidity manual observation values of Nancheng station are close to the automatic observation results, 97.25% of the monthly mean relative humidity of manual observation is higher than that of automatic observation. 75.49% of the time-to-time observed relative humidity was higher than that of the automatic observation, and the difference between the time-to-time observed relative humidity and the automatic observation was mainly between-5% and 10%. Based on the observation record of visibility, this paper analyzes the occurrence time of haze, light fog and fog according to the statistics of relative humidity by manual and automatic observation. The results show that the relative humidity system is lower after automatic observation of relative humidity, as a result, the observed records of haze at Nancheng station increased obviously, and the light fog decreased, but the effect on the observed records of fog was not significant.
