Abstract：As the 4th sub-project of the 973 project “New paradigms for petascale scientific computing”， the research focus of the project “Climate system model high-performance computing and applications” includes high-performance computing and applications for complex fluids in climate and rarefied atmosphere， and climate modeling with 100 billion degrees of freedom. The main tasks are to develop high-performance and resolution sea ice-ocean model and climate system model， handling 100 million grids， 100 billion degrees of freedom， and running on 1000-10000 computing coresconduct short and long-term climate prediction using improved models， participate in the international climate model intercomparison project， investigate variability and prediction of east Asian climate and sea ice， provide numerical simulation strategies for higher-order regularized moment equations based on modified R13 equations and carry out high-level atmospheric fluid dynamics simulation. This is the annual report of the project for the year 2011.

Key Words：Sea ice-ocean model；Climate system model；High-performance computing；East Asian climate；Regularized moment equation
