中文摘要: 详细分析了目前短时临近预报系统对自动气象站数据质量控制、探测数据更新频率、组网雷
达时间同步观测与基数据实时传输、探测数据的实时传输技术、基于目录监控的数据监控与
分发机制、基于开源的软件开发、数据格式等方面的需求。在此基础上，建立了北京奥运短
时临近预报数据快速收集处理系统并已经投入业务运行，该系统实现了探测数据的实时传输
、组网雷达时间同步观测和基数据实时传输、基于消息驱动的数据实时监控和分发、探测数
据格式规范化等功能，基本满足北京2008年奥运短时临近预报系统的数据预处理业务需求。
Abstract:The data processing kernel problems of the very short range and nowcasting are
analyzed in detail. These include quality control of automatic weather station d
ata，data update frequency, network Doppler radar synchronization observation an
d level II data transfer in time，detecting data transfer in real time，detecti
ng data monitoring and dissemination based on the directory monitoring and messa
ge drive， software development based on the open source technology, and data fo
rmat etc. Some techniques are adopted to meet the short term and nowcastin
g demands. Based on these techniques，the DRAPS （Data Rapid Acquisition and Process Syste
m） of nowcasting for Beijing 2008 Olympic games was developed and run in operat
ion more than one year. Some advanced techniques were adopted in DRAPS，such as
data transfer in real time, network radar synchronization observation， data mo
nitoring and dissemination in time based on message driven, and data format stan
dardization etc. The system basically meets the demands on the data processing f
or very short term and nowcasting.
