This paper is written to commemorate the 10th anniversary of our mentor-academician Ye Duzheng’s pass away and his great contributions to the development of atmospheric sciences in China and Institute of Atmospheric Physics, Chinese Academy of Sciences. This paper aims to make a brief review of his main contributions to the atmospheric sciences. Over more than 70-year research career, he proposed the theory of energy dispersion of Rossby wave, which has been one of classical theories of Dynamic Meteorology. Moreover, he established the theory of atmospheric general circulation over East Asia and the Tibetan Plateau Meteorology. Especially, he proposed a scale theory regarding the adaptation process of atmospheric motion and the new concept of adaptation to global warming. Besides, this paper provides an overview of his outstanding contribution to the development of Institute of Atmospheric Physics, Chinese Academy of Sciences and his serious and careful spirit of scholarship.
