| 摘 要： | 加强对地面资料计算机自动审核技术的研究,对于实现地面气象观测资料的计算机自动审核、提高地面观测资料的审核质量和工作效率具有重要意义。云状记录的排序分析技术,是地面气象观测资料计算机自动审核中的一个关键性技术难点。文章介绍一种分类分析方法,即根据总云量、低云量和云状的不同配合情况分为几种记录类型,对每一种类型再根据几种不同情况进行分析,在分析判断过程中,将29种云状符号射影到双字(32位)变量中,使分析判断程序简单明了。在浙江省地面气象资料计算机自动审核软件中进行试用,结果表明该方法对提高云观测资料的审核质量具有明显效果。

| Abstract: | It is very important to develop computerized surface meteorological data examination technology for improving data quality and data processing efficiency.The ordination analysis technique of cloud records is one of key difficulties in surface meteorological observation data examination.A classification analysis method is introduced,which divides the cloud records into several types according to various collocations of total cloudiness,low cloudiness,and clouds forms,and for each type,the analysis is made respectively according to various circumstances.In the analysis,the cloud symbols of 29 types are projected into the two-word(32 bits) variables,which makes the analyzing procedure simple and clear.As a test,the software has been applied in the artificial examination of surface meteorological observational data in Zhejiang Province.It has been proven that this method is very useful in improving the cloud observation data examination quality. |
