| 摘 要： | 目的]设计和推广固原市中雨、大雨、暴雨相似预报系统。方法]采用C#.Net2005作为开发平台,基于MSSQLSERVER2005数据库系统,统计固原市自1960年以来逐年5～9月出现中雨、大雨、暴雨过程的高空环流形势,以500 hPa为主,700 hPa和地面形势为辅,分别计算500、700 hPa的相似离度,按照历史上出现过的最相似个例来类推预测今后将要出现的天气过程和天气现象。结果]该系统设置非常人性化和模板化,系统设置仅需要一次设置即可,除非需要更改设置,系统运行一般不需要更改参数,系统会自动读入设好的参数,方便业务人员使用,同时也解决大量数据在一个字段存贮的难题。系统在设计的过程中考虑了推广应用问题,设计上具有通用性和可移植性。结论]该系统弥补数值预报产品漏报中雨、大雨、暴雨的可能性。

| Abstract: | Objective] The aim was to design and promote similar report system of moderate rain,heavy rain and rainstorm in Guyuan City.Method] As C#.Net2005 development platform and based on MSSQLSEVER2005 database system,the upper air circulation during moderate rain,heavy rain and rainstorm from May to September since 1960,taking 500 hPa,700 hPa and ground situation as complement,the similar height of 500 and 700 hPa were calculated.Result]The system is set to be personal and template.The system only needs to be set for once.If the installation is changed,the system doesn’t need to change parameters.The system would automatically read the parameters and make it easy for the businessman to use.Meanwhile,it solves the problem of storing abundant data.Considering the promotion and application,the system is designed to be universal and portable.Conclusion] The system makes up the possibility of mis-reporting the moderate rain,heavy rain and rainstorm. |
