Problems solved by technology

However, the common practice of adopting a preset and fixed operation process faces at least the problem of system operation failure caused by the failure of the global model forecast field or observation data in actual operation, which leads to the failure of the numerical weather prediction product to be completed on time

For example: ①The global model forecast field provides regional mesoscale model background field and model side boundary conditions, which are key data for system operation. The absence of any global model forecast field with forecast timeliness will cause interruption of system operation, not only causing waste of computing resources, but also Operational failures will also lead to the loss of numerical forecast products. In actual operations, the phenomenon of operational failures due to the lack of all or part of the time-sensitive data in the global model forecast field occurs from time to time

② Due to various unexpected reasons, such as observation data upload and download failure, network failure, server address, user name, password or path change, data file name change, data format change, etc. There is a problem in the data collection and decoding process. When the system performs data assimilation according to the fixed operation process, there may be a program failure and cause the operation to be interrupted. This kind of failure also occurs from time to time in actual business.

The first question is the key technical step to realize lightning data assimilation, and the second question is the key to realize real-time business operation of lightning data assimilation
