| 摘 要： | 本文从湍流产生和发展的本质出发，以湍流动能和湍流混合长为湍流输送的决定因子，用因次分析的方法得到了一套可包括局地自由对流在内的不稳定大气近地层Monin－Obukhov相似性函数。这套相似性函数不仅有较充分的理论依据，而且还有较明确的物理含意。它能在极端情况下自动蜕化出局地自由对流相似性预测形式。

| Abstract: | In this paper Monin-Obukhov similarity functions,embeded with local free convection,of surface layer in unstable atmosphere are obtained by using dimensional analysis,in view of turbulent generation and development, based on determinative factors of turbulent transport---turbulent dynamic energy and mixing length. This set of functions may only relate to full theoretical bases, but also has clear physical meanings. It can automatically reduce to predicted form of local free convection under extreme conditions. |
