Grid computing has emerged as an important new field. Based on an open set of standards and protocols, grid computing enables the organizations around the world to access the data resources, storage capacity and the distributed heterogeneous computing etc. via internet or local network to create a single system image, ultimately it can grant users and applications seamless access to vast computing environments. Because of its huge computing requirement, high throughput and dense service, meteorology has become one of the significant application fields in the proposed world's grid projects, such as ECMWF's EcAccess system, MEAD Project of US, Europe, Japan, etc. With grid computing, organizations can optimize distributed heterogeneous computing, human expertise and data resources, can share them across networks and can provide a remote collaborative environment for NWP as well as the Earth simulation system.
