摘 要:为了研究同一气候、同一环境背景下不同观测系统观测资料的差异性,利用琼山国家一般气象站2014年10要12月DZZ4与ZQZ-CII型自动气象站气温、风向风速、0~320 cm地温等资料进行对比分析,结果表明:①2种型号自动站观测数据具有较高的一致性,其中DZZ4型观测数据变化表现相对稳定。②日平均气温差为0.2益,平均气温、日极端气温差异不显著。③2 min、10 min平均风速差分别为0.08、0.03 m/s,风速一致率分别为68.50%、93.70%,风向相符率分别为68.2%、85.9%,平均风观测时间越短,风速差变大,风向相符率变低。④0~5 cm地温、地面最高温度平均差均大于0.5益,地面最高温度平均差为2.4益,地面最低温度及其他层次地温差很小。地温随深度增加,变化减小,两站的地温差变小。⑤通过建立的回归方程,有效地实现DZZ4与ZQZ-CII型自动站气象资料的互补,确保资料完整性。To study the difference of data observed on a same environmental background with a same observing system for a same climate,data including air temperature,wind direction,wind speed,and 0 -320 cm earth temperature,etc, collected from DZZ4 and ZQZ-CII automatic meteorological stations in Qiongshan National Common Meteorological Station from October to December in 2014 were used for comparison and analysis.The results as follows : (!)Data observed by the two types of automatic meteorological stations were high complying with each other, data change collected by DZZ4 was relatively stable.The daily mean air temperature difference was 0.2℃ ,and there was no significant difference of mean air temperature and extreme daily air temperature.The mean wind speed difference at 2 minutes and 10 minutes whith were respectively 0.08 m/s and 0.03 m/s, the wind speed conformities were respectively 68.50% and 93.70%,the wind direction conformities were respectively 68.2% and 85.9%, and the wind speed difference enlarged and the wind direction conformity degraded in a shortened observation time.(~)The earth temperature and mean difference of maximum earth temperature at 0-5 cm were larger than 0.5 ~C, the mean difference of maximum earth temperature was 2.4 ~C, and the minimum earth temperature with other earth temperature difference at other layers was small.The earth temperature changed decreasingly with depth increasing, and the earth temperature difference narrowed between the two stations.A regression equation was created so that the meteorological data from DZZ4 and ZQZ-CII automatic stations could be compensated for each other, and the data could be completed.
