The complex terrain,vulnerable infrastructure,lagging communication network,all pose restriction on the meteorological monitoring and management in Three-river headwaters region of Qinghai province.Based on technologies of workflow,software metrics and configuration management,we designed an emergency warning and management system for disastrous weather,which is in accordance with the Capability Maturity Model (CMM) standard.The system is aimed to achieve secure and rapid information communication,thus improve the response and management of disastrous weather events.The disastrous weather database is established to electronically and intelligently manage the meteorological disaster information such as flood,drought,typhoon and sandstorm,which is the basis for emergency warning and response.The access to internet provides integrated services of map,text,table,and control for the management system.
