| Abstract: | According to the business requirements of meteorological risk and warning on small watershed flood, mountain torrents and geological disasters in Jiangxi Province, the technology of radar quantitative precipitation estimation（QPE）, boundary extraction of watershed, critical rainfall threshold determination and further development of SWAN system were applied to business services system, which led the risk warning service from typical regional warning service to the whole province. And the key technologies provided the technical support for the meteorological disaster risk warning service. |
