Who invented the semi-implicit difference method?

The semi-implicit difference method was invented by Zeng Qingcun.

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 meteorological satellite remote sensing.

Zeng Qingcun's early experiences:

1935 In May, Zeng Qingcun was born in a poor peasant family in Yusha Village, Ganglie, Jiangcheng District, Yangjiang City, Guangdong Province. His brother Zeng Qingfeng is a geologist. 1September, 952, graduated from Yangjiang No.1 Middle School and was admitted to the Physics Department of Peking University. Because there was an urgent need for meteorological science talents in New China at that time, he served the needs of the country and chose the meteorological major of the Department of Physics.

June 65438+July 0956, graduated from undergraduate course. In June of the same year 165438+ 10, he was selected to study in the former Soviet Union, entered the Institute of Applied Geophysics of the former Soviet Academy of Sciences, and studied under the meteorologist Kibir. 196 1 March, graduated from the former Soviet academy of sciences with an associate doctorate. After returning to China, he entered the Institute of Geophysics, Chinese Academy of Sciences, and successively served as an assistant researcher and researcher.

1966 1, the Chinese Academy of Sciences decided to separate the meteorological laboratory from the Institute of Geophysics and formally established lasg, where Zeng Qingcun worked.
