AWARDEE OF  METEOROLOGY  PRIZE

LI CHONGYIN

Li Chongyin, a meteorologist, born in 1940 at Daxian in the Sichuan Province. He graduated from the Department of Geophysics, University of Science and Technology of China in 1963. Since then, he has been engaged in meteorological research all along in the Institute of Atmospheric Physics, Chinese Academy of Sciences. He has achieved systematic and innovative achievements in the frontier fields of atmospheric science, such as tropical meteorology, dynamics of atmospheric low frequency oscillation, ENSO cycle dynamics. Particularly he made outstanding contributions to push the development of tropical meteorology and climatic dynamics. In the studies on atmospheric low frequency oscillation, he systematically demonstrated the characteristics of atmospheric low frequency oscillation, advanced atmospheric low frequency teleconnection / low frequency remote response theory and its dynamical mechanism. In the studies on dynamics of the atmospheric intraseasonal oscillation, he advanced and consummated the CISK wave theory of tropical intraseasonal oscillation. At first in the world he indicated that the convection heating feedback (CISK) is an important mechanism to excite tropical intraseasonal oscillation and then he showed the importance of the CISK-Rossby wave to drive tropical intraseasonal oscillation as well as the CISK-Kelvin wave. In the studies on ENSO cycle dynamics, he not only indicated the important effects of the ENSO on the temperature and precipitation in eastern China, and the activity of typhoon over the western Pacific, but also, more important, got innovative achievement in the occurrence mechanism of El Nino event. He revealed the important impact of anomalous winter monsoon in East Asia on the occurrence of ENSO. He also indicated that the premonition of an El Nino event is in the equatorial western Pacific region and the subsurface ocean temperature anomaly in the warm pool and its eastward propagation play a key role in occurrence of the ENSO. Thus a new concept on essence of the ENSO is advanced. In the studies on satellite remote sensing theory, he indicated the problem with infrared remote sensing of atmospheric humidity in the United States and advanced concrete plan to develop meteorological satellite in China. Through some computations, he still discovered the trouble with a certain satellite in China and advanced solving method. He also achieved a series of achievements with international impact in typhoon dynamics and tropical meteorology.
