1. Strategic Plan for Korean Participation in T-PARC 2008 Hee-Sang Lee Forecast Research Lab., NIMR/ KMA April. 7-8, 2008 Tsukuba, Japan

2. Strategy and scientific Plan for T-PARC 2008 ● Contribution to improve forecast accuracy of high impact weathers and to accumulate experiences on observing systems in various platforms by actively participating international collaborative observation programs related to THORPEX/T-PARC. ● Improvement of the accuracy of medium-range forecasts through promotion of the global prediction system's performance. ● Concentration of the investment to research and development in high- resolution numerical modeling, adaptive observation, data assimilation, OSSEs/OSEs, and observing systems. ● Continuation of an IOP after KEOP to improve the forecast accuracy and understanding of characteristic meteorological phenomena in Korea. It is essential to make the IOP be comprehensive for effective linkage among other observation programs. ● Usage of strategic scientific issues of THORPEX in the GEOSS to compensate the weak points, then feedback into THORPEX to keep complementary cooperation between the two programs.
