昆明市SWAN平台的搭建及其与省级SWAN的搭配使用

The Establishment of Kunming SWAN Platform and Its Application with Provincial SWAN

强天气短时临近预报系统(SWAN)的推广应用是提高气象业务水平的重要途径。文章从基础数据准备、系统服务器平台搭建、客户端安装及本地业务化应用4个方面,简述了SWAN在昆明市气象局的搭建过程和应用,通过比较分析指出云南省和昆明市两级SWAN系统在雷达相关产品、自动站观测资料上的差异表现:产品及时率、站点密度和部分区域产品准确率不同,指出SWAN系统有待完善之处,建议搭配使用省、地两级SWAN系统产品,以发挥各自长处、弥补不足,提高短时临近天气预报水平。

The popularization and application of Severe Weather Auto Nowforecasting(SWAN)system is an essential way to im-prove the meteorological operation level.This paper introduces the building process and application of SWAN in Kunming Meteoro-logical Bureau from four aspects:basic data preparation,system server platform construction,client installation and local business ap-plication.Through comparison and analysis,the difference between SWAN systems of Yunnan Province and Kunming City in terms of radar-related products and observation data of automatic stations is figured out:the timely rate of products,the density of stations and the accuracy rate of products in some areas are different,and it is pointed out that the SWAN system needs to be perfected.It is suggested that the products of provincial and municipal SWAN systems should be used together to make full use of their respec-tive strengths and make up for their deficiencies,in order to improve the level of Severe Weather Auto Nowforecasting(SWAN).
