新型站视程障碍类天气现象判识规定的思考

Thoughts on the identification of the weather phenomena of the new type of visual obstruction

应用鄯善站1981—2013年人工观测视程障碍类天气现象和2014—2016年能见度仪自动观测视程障碍类天气现象资料,对新型自动站ISOS软件判识视程障碍类天气现象出现的问题进行总结,通过实例对比分析视程障碍类天气现象人工与自动观测存在差异性,同时就错误判识结果提出合理化修改建议。

The visual obstruction weather phenomena manually observed at Shanshan Station from 1981 to 2013 and the weather data of visual obstruction automatically observed by visibility meter from 2014 to 2016 were utilized to explore and summarize the problems found in using ISOS software to identify visual obstruction weather phenomena. The comparative analysis of examples differences between manual and automatic visibility observation was con- ducted and in view of the mistaken identification result, optimization suggestion was proposed to improve the visibil- ity and availability of meteorological data of automatic observation.
