全国气象干旱监测预警业务试验平台设计与实现

针对干旱监测预警业务及科研需求,在WINDOWS系列操作系统平台下,采用SQL SERVER2005数据库,建立了全国720个国家级站点自建站以来日最高最低气温、日降水量、日照时数、日蒸发量等要素历史和实时资料数据库,实现了实时、历史资料的对接,为干旱监测预警业务试验提供了资料保障。在此基础上,采用C#等开发工具,设计开发了全国气象干旱监测预警业务试验平台,该平台整合了K、SPI、CI等干旱指数算法,实现了气象要素的多条件灵活查询、统计计算及指数计算等功能,提供了色斑图、折线图、EXCEL表等形式多样的产品表达方式。

Design and Implementation of Test Platform on the Meteorological Drought Monitoring and Early Warning Service in China

To meet the business and scientific research requirement on drought monitoring and early warning,a database,which con-tains historical and real-time time series data of meteorological elements including daily maximum temperature,daily minimum tem-perature,daily precipitation,daily sunshine hours and daily evaporation at 720 meteorological stations throughout China since their es-tablishment,was established on Windows platform by using SQL SERVER 2005 database.The database not only realized the joint of real-time and historical data,and importantly it provides data storage services for the drought monitoring and early warning service. On this basis,the test platform of meteorological drought monitoring and early warning service was developed by C#and other langua-ges.The platform integrated the algorithm of K,SPI and CI drought index,which realized the flexible query by multi-condition and statistic of meteorological elements,and the drought index calculation,etc.In addition,it provides various formats product,such as stain chart,line chart,and EXcelltable.
