Who created the world numerical weather forecast?
Zeng Qingcun, an internationally renowned atmospheric scientist, is one of the founders of international numerical weather forecasting. 1935 was born in yangjiang city, Guangdong province; 1956 graduated from the physics department of Peking University; 196 1 obtained the associate professor of the institute of applied geophysics of the former Soviet academy of sciences.
He once worked in the Institute of Geophysics and the Institute of Atmospheric Physics of Chinese Academy of Sciences, and served as the director of the Institute of Atmospheric Physics. 1980 elected member of China academy of sciences (academician).
In the past 60 years, he has been active in the forefront of atmospheric science research and has made pioneering and systematic contributions to the basic theoretical research of numerical weather forecasting. He put forward the "semi-implicit difference method" for the first time in the world, and successfully realized the numerical weather forecast with the original equation for the first time.
This work has become a milestone in the development of numerical weather forecasting. The theory and quantitative inversion method of meteorological satellite atmospheric infrared remote sensing system are established, which makes a pioneering contribution to the remote sensing of high noise mu meteorological satellite.
achievements in scientific research
Zeng Qingcun is in his doctoral thesis. He is the first person in the world to use primitive equations to make numerical weather forecast. "Semi-implicit sum-difference method" is still one of the core technologies of weather and climate numerical model, which has been widely used in various disciplines and become one of the mainstream algorithms of contemporary supercomputing.
Semi-implicit difference method is the earliest method to successfully integrate the original equation, which creates a difference scheme that strictly maintains the conservation of Arson-Arson energy, thus completely overcoming the instability of nonlinear calculation and being widely used. A strict theory of geostrophic adaptation process is established; Solve some basic problems in geophysical fluid dynamics; In order to select the remote sensing channel reasonably, the theory of optimal information layer is put forward.
The atmospheric circulation model, ocean circulation model and climate system model designed by him and his research group can successfully simulate the passage of Asian monsoon rain belt, ocean circulation and China offshore circulation system (such as South China Sea warm current). ) and successfully applied it to the inter-seasonal drought and flood prediction in China; The numerical method is also successfully used to simulate the process of river and lake deposition and delta development.
