The distribution of high performance computing resources is inhomogeneous geographically.As a result,some local meteorological bureaus fail to conduct local meteorological forecast operations or researches.Thereby,funded by"National Science and Technology Infrastructure Plan",the resource integration and management are done by China Meteorological Administration. It hoped to realize the sharing of resources in CMA and increase the effectiveness of resources'utilization.As a node,Liaoning Meteorological Bureau joined the national meteorological network computing application system.It is an urgent task for Liaoning Meteorological Bureau to upgrade system management from homogeneous systems to global system management across multiple heterogeneous systems. Regarding the requirements of resource integration, sharing and management by Liaoning meteorological department, a design scheme of Liaoning meteorological computing application system is proposed. The scheme utilizes computational grid as the platform building technology. The design scheme includes user interface, grid management, high performance computer local management. Regarding the integration requircment of heterogeneous computing resources, a solution is proposed consisting of globally coherent, centralized user management and meta-scheduler of job management. To build a uniform grid application support environrnent, schemes are proposed for typical meteorological grid applications and application interfaces respectively.In conclusion, an implementation of Liaoning meteorological network computing application system is proposed based on the requirements of meteorological services, with which immediate and efficient supports are supplied.
