| description | Numerical weather prediction research and development experiments are the key technical means to improve the model performance. The model experiment management system is an essential platform that enables model experts to conduct experiments effectively. To address the need for a coordinated development mechanism in numerical weather forecasting and drawing from relevant domestic and international research, an online interactive experiment management system for numerical weather prediction models has been designed. The system utilizes a browser/server (B/S) software deployment architecture, which consists of four layers on the server side: Application layer, support layer, data layer, and resource layer. The application layer offers management functions at the user application level for modeling experiments. Software modules of the support layer are designed to address the needs of various scenarios and are integrated to provide services that can be accessed by the application layer. The data layer offers a comprehensive data management platform service for the entire system. The resource layer provides foundational support in terms of computing power, data, and code. The system offers functions for template editing, process arrangement, and instance construction, facilitating the flexible and rapid design of model experiments. All modules are fully interconnected and can be accessed in a single, convenient location. The system has enhanced the operational efficiency of model experiments and improved user experience through methods such as case data governance and program code artifact caching. The system provides full support for the entire process of model experiments, including the design and definition of model experiments, data acquisition for experiment instances, creation and operation, job monitoring and management, and the visualization and analysis of results. The system has been developed using a framework that separates the front end from the back end. The front end incorporates load balancing and horizontal scaling, while the back-end services are loosely coupled and can be deployed independently. The system has been operational since 2023 and has facilitated the coordinated development of numerical weather forecasting at both national and provincial levels across various scenarios. As research in earth system modeling and prediction advances, the model experiment management system will undergo further upgrades and continuous improvements to enhance its functionality and technical implementation. |
