Based on the workflow engine technology associated with serviceoriented architecture (SOA), this paper explores a task scheduling architecture for weather and climate management operation, which meets the needs of flexible and convenient scheduling and control of operation nodes, processes and scenarios. Through the integrated management and control of the nodecentered function algorithm, the component registration and resource reuse functions of the process nodes are realized. Through the configurable process assembly mode, weather and climate management can be changed quickly by service choreography. By the capability of visual process choreography, it is possible to monitor the processing of various processes accurately and conveniently. After the trial operation of this architecture which has been put into operation, the realtime operation requirements can be satisfied.
