摘　　要：在现有的气象业务中,各种气象资料接收和发送时间的准确同步对科学研究和业务应用起着重要的作用,气象业务全网的时钟同步需求也是愈加迫切。介绍了网络时间协议(NTP)的基本原理、工作模式和体系结构,通过在局域网内搭建Linux服务器下的时钟同步服务器,以广州区域中心时钟服务器为上级服务器,构建广西气象业务时钟同步网,在业务应用中取得了较好的效果。In the existing meteorological operational system,the synchronization of the reception and sending of all kinds of meteorology data plays an important role in the meteorological operations and scientific research,and the clock synchronization of the whole meteorological network is even more urgent in need.The basic principle,the work model and the architecture of the Network Time Protocol（NTP） have been introduced in this paper,and a Guangxi Meteorological Operational clock synchronization network which is build in the LAN,operated under the Linux sever and acted as a lower level of the clock synchronization network of GuangZhou Regional Center has proved to be effective in practice.
