摘要
实现地面气象要素自动观测是近年来我国气象观测领域的发展趋势,观测自动化给地面观测业务和观测数据的应用推广带来较大改变。本文研究了基于自动观测的天气现象代码表WMO4680,分析得出WMO4680简化了视程障碍和降水阵性的代码分类,比WMO4677编码更适合自动观测设备的特点。结合我国业务天气现象电码编制原则,设计实现了现在天气现象电码和过去天气现象电码的自动编制。根据我国目前可自动化观测的要素数目,经过流程设计和当前最新业务改革内容,可以实现46个天气电码的自动编报。
The automation of some traditional artificial observations such as clouds and weather phenomena has profound influence on the daily observation operation,which affects data storage and data exchange as well.The characteristics of the World Meteorological Organization code table 4680 are discussed,and it is discovered that it is more suitable for automatic weather observation.Based on the newly formed rules and regulations in atmospheric observation,the automatic coding of present weather and past weather is designed.Taking the coding principles and weather characteristics into accounts,the antomatic coding of 46 codes is realized automatically.
