Weather services products generation system based on GIS geoprocessing

With increasing use of weather observation and forecast services, there is an urgent need of an effective and efficient system to generate high-quality weather services and products. For example, weather maps are expected to be submitted not only for decision-making departments but also to websites whose main feature is to provide public service products on a daily or an hourly basis. In this study, first, geoprocessing is successfully extended to handle the entire process of weather map generation from data, and some associated key issues are discussed. Second, based on the distributed computing technology, an application system with multitiered architecture for weather services products generation system is designed and implemented. The system significantly enhances sharing and scalability. Finally, an application case is studied in detail by illustrating modeling, task deployment, and final execution, and it is shown that the operational system meets the requirements of simplicity, easy modeling, and customizable task deployment.
