Wang Bin first put forward the theory of cooperative dissipative operator in the world, and took the lead in constructing a series of new algorithms suitable for numerical simulation of atmospheric ocean, such as explicit square conservation difference scheme, symplectic operator method and generalized Hamiltonian algorithm, weighted equal area grid generation method, flexible jump point difference method and semi-analytical energy conservation scheme. He led his research group to successfully apply these new theories and methods, designed the world's first dynamic framework of global atmospheric model with adjustable resolution, which can strictly maintain the conservation of effective energy and can operate stably without any smooth filtering, and established a new generation of 26-storey high-resolution atmospheric circulation model with international advanced level and China characteristics; Symplectic geometry algorithm is first applied to the assimilation of GPS/MET variational data in the world, and it saves more than 1000 times by combining variable step size technology and parallel technology. In particular, the variational assimilation method has been successfully applied to typhoon initialization and precipitation data processing at stations, which greatly improves the simulation of typhoon intensity and path and improves the accuracy of rainstorm forecast.

He and his research team put forward a new concept of mapping observation and a new idea of reverse four-dimensional variational assimilation for the first time in the world, aiming at the key difficulties that classical three-dimensional variational data assimilation is not in harmony with the model because of lack of model constraints, and four-dimensional variational data assimilation is difficult to be popularized and applied in operational numerical weather forecast because of huge calculation. On this basis, they established a brand-new variational data assimilation method: three-dimensional variational mapping data assimilation, which not only improved the assimilation effect on the basis of two classical methods, but also saved more than 20 calculations. This achievement was especially presented at a series of international conferences (1500 participants) in 2005, which was highly praised by international authoritative experts in the same field.

Because of his outstanding achievements, he was promoted to deputy director of the State Key Laboratory of Numerical Simulation of Atmospheric Science and Geofluid Dynamics (LASG) as soon as he left his postdoctoral position in 1996, and was promoted to researcher at the end of the same year. 1997 was promoted to doctoral supervisor, and 1998 won the National Science Fund for Distinguished Young Scholars. 1999 presided over the first topic of the 973 project "Large-scale scientific computing research", "High-precision calculation of complex flows", and was selected as the first and second floors of the national "100 million talents project" in 2000. 200 1 Received special government allowance and was elected as the director of LASG State Key Laboratory. In 2002, as one of the leaders, he was supported by the Innovation Group Project of the National Natural Science Foundation of China. In 2005, the 973 project "Research on High Performance Scientific Computing" jointly applied by him, Institute of Computational Mathematics of Chinese Academy of Sciences and Peking University was approved, and the third project he presided over was "Research on High Performance Algorithms for Complex Flow Problems". Published 87 papers, including 36 SCI papers and 4 EI papers. Writing a monograph, supported by the Science Publishing Fund, will be published soon.
