区域气象观测资料分析应用系统

Analysis and Application System of Regional Meteorological Observation Data

"区域气象观测资料分析应用系统"应用软件主要任务是把本地的区域气象站观测资料根据不同需要处理成不同的显示产品,方便分析和应用观测资料,用于日常业务。该软件提供完善的实时显示、历史资料查询与统计功能、数据质量监控。系统采用C/S结构,服务器端以SQL server作存储观测资料数据库,客户端用Visual Basic与MapX开发组件构建应用显示平台。系统具有要素空间分布等值线绘制等功能、天气雷达回波显示功能。该软件可以动态、及时地了解当地的雨情、气温、地面风大小。与雷达回波相结合,可以辅助预测未来短时间内降水影响的区域和影响程度、还可以辅助判断区域气象站地面降水数据的真实性;借助要素等值线功能观察某个气象要素分布梯度,辅助判断观测设备是否异常;可以设定报警阈值,用声音或动画图像报警;可以制作站点观测数据报表。该软件充分考虑因气象观测设备来自不同的生产企业而产生的数据格式不一致的问题。

The analysis and application system of regional meteorological observation data developed by the Pu’er municipal meteorological service are introduced. The software was constructed as a Client/Server framework, using the Microsoft SQL_server Database to store observation data. Based on the integrated technologies of Microsoft Visual Basic and Mapinfo Mapx activeX, an application platform was constructed. The integrated functional modules are able to display, inquire, analyze, and process various meteorological data, such as contour line drawing for meteorological elements, weather radar echo displaying, and audible or animated graphic alarming. The major functions and working principles of the system are introduced, and its application effects in meteorological services are described.
