Abstract: Since the concept of chaos was put forward, some problems of atmospheric turbulence should be further investigated. In this paper, author's opinions on following problems are put forward: (1) the atmospheric turbulence can be described by deterministic dynamical system, (2) the atmospheric turbulence can be investigated in terms of finite dimension dynamical system, (3) the velocity shear ∂u/∂z have dual charawer, (4) turbulenec can occur in stable stratified co-ndition, (5) how is the critical Richardson number? (6) the universality and limitation of Lorenz equation, (7) are atmospheric turbulence disorder? (8) the different route to turbulence at daytime and at night.
