Abstract:In order to solve the problem that the flood control department is difficult to obtain the rainfall information in time and effectively, the key technologies such as the intelligent correlation of typhoon rainfall information, the nesting fusion of the multi mechanism rainfall forecast and the spatio-temporal analysis of the rainfall forecast data was applied to design a cloud platform for real time flood control information of typhoon. Based on B/S framework, SaaS service mode, and data and service capability center, the universality and stability of the system are guaranteed. The practicability of cloud platform is achieved through the function design of typhoon information, similarity analysis, future rainfall, analysis bulletin and data screen. The cloud platform is applied to flood control work in Ningbo and Wenling, showing that the system is practical, reliable and effective.
