The distribution of high performance computing resources is inhomogeneous ge ographically. As a result, some local meteorological bureaus fail to conduct loc al meteorological forecast operations or researches. Thereby， funded by “Natio n al Science and Technology Infrastructure Plan”, the resource integration and ma nagement are done by China Meteorological Administration. It hoped to realiz e 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 Meteorologi cal 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 departme nt, a design scheme of Liaoning meteorological computing application system is p roposed. The scheme utilizes computational grid as the platform building technol ogy. The design scheme includes user interface, grid management, high performanc e computer local management. Regarding the integration requirement of heterogene ous computing resources, a solution is proposed consisting of globally coherent, cen tralized user management and metascheduler of job management. To build a unifo r m grid application support environment, schemes are proposed for typical meteoro logical grid applications and application interfaces respectively. In conclusion, an implementation of Liaoning meteorological network computin g application system is proposed based on the requirements of meteorological ser vices，with which immediate and efficient supports are supplied.
