江门地区初春大雾的预报预警业务系统

介绍江门地区大雾天气分型预报业务系统。该系统采用Delphi语言编写程序、应用Access作为数据库进行开发，并采用人机交互方式，简化了预报流程，减少工作量，为及时、准确发布大雾预报和预警信息提供依据。该系统通过自动读取Micaps实时数据，以人工判断锋面、倒槽、切变线等有利于春季大雾的天气形势为辅助，对江门地区初春大雾天气做出客观预报，并对预报结果进行自动检验。

The Operational Forecast and Warning System for Early Spring Fog Event over Jiangmen Area

The operational system for dense fog forecast over Jiangmen area of Guangdong province during early spring was developed in Delphi with Access database. In a man - machine interaction way, it simplifies forecast procedures, reduces daily workload and helps forecasters issue warning and forecast for heavy fog event over the area timely and more accurately. With manual analysis of synoptic systems favorable for dense fog onset in early spring including frontal surface, inverted trough and shear line, the system produces objective forecast for heavy fog and real - time automatic verifications based on the MICAPS observational data.
