摘要
浑沌(chaos)概念的提出,有关大气湍流的若干问题有深入讨论的必要。根据我们近几年研究对如下问题提出自己见解,供深入讨论:确定的动力系统可以描述大气湍流,大气湍流可以用有限维动力系统来研究,速度切变?u/?z有两重性,稳定层结下可以出现湍流,Lorenz方程的意义及局限性。
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 i-nvestigated in terms of finite dimension dynamical system, (3) the velocityshear have dual character, (4) turbulence can occur in stable stratified condition, (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.
