File photo taken in 2015 shows Zeng Qingcun, a famous meteorologist from the Institute of Atmospheric Physics (IAP) under the Chinese Academy of Sciences (CAS), speaking at the International Conference on Industrial and Applied Mathematics in Beijing, capital of China. Zeng Qingcun received China's top science award on Friday for his outstanding contributions to scientific and technological innovation at an annual ceremony held in Beijing to honor distinguished scientists, engineers, and research achievements. Zeng, 85, is a famous meteorologist from the Institute of Atmospheric Physics under the CAS. His theory of numerical weather prediction solved the problems of timeliness and stability in calculating multi-scale weather change processes and is the basis of the global numerical weather prediction technology. Zeng's visionary study on global climate change has brought him a host of accolades and international acclaim, including the world's top prize for meteorological work. (IAP of CAS/Handout via Xinhua)
