广西对流尺度数值预报数据传输系统的设计与实现

Design and implementation of data transmission system for convective scale numerical prediction in Guangxi

数值天气预报在防灾减灾工作中发挥了越来越重要的作用,为了保障广西对流尺度数值预报产品的传输质量与时效,搭建了广西对流尺度数值预报数据传输系统。文中阐述了该系统的设计思路,并对网络部署、服务器搭建、数据自动收发、传输过程的实时监控等关键技术进行详细介绍。系统的业务运行分析评估结果表明,该系统GIF和Grib数据的整体传输时效分别为8min和5min,数据完整性高、利于用户便捷高效地获取数据,能够实现运行状态自监控且运行稳定。

Numerical weather forecast plays a more and more important role in disaster prevention and reduction. In order to ensure the transmission quality and timeliness of convective scale numerical forecast products in Guangxi, a convective-scale numerical forecast data transmission system was established. This paper expounds the design idea of the system, and introduces in detail the key technologies such as network deployment, server construction, automatic data sending and receiving, as well as real-time monitoring of transmission process. The business operation analysis and evaluation results of the system show that the overall transmission time of GIF and Grib data of the system is 8 minutes and 5 minutes respectively. The data integrity is high, which is conducive to users to obtain data conveniently and efficiently, and can realize self-monitoring of operation status and stable operation.
