摘要
利用现有气象设备,采用多种高级编程语言,研就开发了哈尔滨机场雷暴分析预报系统.该系统利用现有气象信息网资源,实现初始数据自动读取和综合分析处理;采用相似分析技术,实现雷暴天气形势的自动相似判别;利用天气学方法和数理统计方法,建立集成分析预报模式,实现0～24 h雷暴概率短期预报;基于天气雷达回波,采用交叉相关算法,实现0～1 h强对流临近预报预警.
By means of the existing meteorological equipments and a variety of high-level programming languages, the thunderstorm forecasting system in Harbin airport is researched and developed. Based on the meteorological information network, the initial data can be read and analyzed automatically. The thunderstorm weather situation can be discriminated automatically by using the analog discriminatory analysis method. The weather forecast model is established by adopting synoptic forecasting and mathematical statistics method,which can issue 0-24h thunderstorm probability prediction. According to weather radar echoes and cross-correlation method, severe convection weather is predicted and warned within one hour.
