城市酸雨预报方法及业务系统

Operational System of Urban Acid Rain Prediction

应用欧拉酸沉降数值模式、基于主分量的神经网络预报方法、动态统计预报方法,建立了广西城市酸雨预报模型,进而根据酸雨预报业务流程,将预报方法、Sybase数据库和网页技术等有机地结合起来,研制了广西城市酸雨预报业务系统。一年多的业务应用表明,该酸雨预报系统性能稳定、技术成熟、自动化程度高。

Based on the numerical prediction model of Euler acid deposition, the ANN （artificial neural network） model, the principal component analysis and the dynamic-statistic prediction method, the urban acid rain prediction model of Guangxi is established. The platform is set up according to the working procedure, combining forecast, Sybase database and network technique together. The prediction practice for more than one year indicates that the system performs stably and is highly automatic.
