区域自动站降水分时统计关键技术与实现

Research and Implementation of Precipitation Timesharing Accounting Key Technologies for Regional Automatic Station

利用2008-2019年广西区域2500个自动站小时分钟降水数据,采用基于多线程技术对自动站小时分钟降水数据中的无降水数据进行筛选,通过数据预处理剔除冗余数据仅保留有降水的数据。研究结果表明,处理耗时较直接通过数据库进行查询读取统计的方式减少90%,并且通过对比分析发现,数据总体可用性高达95%。由此可见,高效的处理方式和数据的高可用性,为广西暴雨洪涝风险普查提供了良好的数据支撑和参考依据。

In this paper, based on multi-threading technology, the precipitation-free data of automatic station hourly and minute precipitation data are screened, and the redundant data are eliminated through the pretreatment process, only the precipitation data are retained. The processing time is reduced by 90% compared with directly querying through the database, and the overall availability of the checked data is up to 95%. The efficient processing method and the high availability of the statistical results provide good data support and reference basis for the storm flood risk survey in Guangxi.
