贵州省常规站海平面气压疑误信息分析

Analysis on the Suspicious Information of Sea-level Pressure of Conventional Stations in Guizhou Province

之前有学者研究发现无人自动气象站海平面气压疑误信息出现的主要原因是数据采集端的气压传感器海拔高度参数设置有误,针对常规站的海平面气压疑误信息频发站点修正之后,仍旧存在某些常规站(即之前的区域自动站)海平面气压疑误信息频发。该文给出另外一种导致气象资料业务系统(MDOS)中海平面气压疑误信息频繁出现的原因,从根本上解决部分常规站海平面气压长时间未通过内部一致性检查的现象,为相关台站解决此类问题提供可靠依据。

Scholars have found that the main reason for the sea level pressure suspicious information of theunmanned automatic weather slation is that the pressure sensor altitude setting of the observation equipment isincorrect.After the frequent correction of the sea level pressure suspicious information for conventional stations,there still exists a certain case that some conventional stations(that is,the previous regional automatic stations)have frequent sea level pressure suspicious messages.This paper presents another case of frequent occurrence ofsea level pressure suspicious information in the Meteorological Data Operational System(MDO5),whichfundamentally solves the problem that the sea level pressure of some conventional sltations has not passed theinternal consistency check for a long time.The phenomenon provides a reliable basis for relevant stations to solvesuch problems,and altracts the attention of relevant observation departments.
