Abstract: This paper commemorates the 10th anniversary of our mentor and academician Prof. Ye Duzheng’s passing and his great contributions to the development of atmospheric sciences in China, particularly at the Institute of Atmospheric Physics, Chinese Academy of Sciences. This study briefly reviews his main contributions to atmospheric sciences. In his research career spanning more than 70 years, he proposed the theory of energy dispersion of Rossby waves, which is one of the classical theories in dynamic meteorology. Moreover, he established the theory of atmospheric general circulation over East Asia and Tibetan Plateau meteorology. In particular, he proposed a scale theory regarding the adaptation process of atmospheric motion and a new concept of adaptation to global warming. This paper also overviews his outstanding contribution to the development of the Institute of Atmospheric Physics, Chinese Academy of Sciences, and his serious and careful spirit of scholarship.
