摘要： 本文在文献[1,2]的基础上,说明坡风是一种耗散结构,并对形成坡风的热力不稳定条件进行了初步讨论,给出了临界瑞利数Rc作为坡风热力不稳定的判据。

关键词: 坡风, 耗散结构, 热力不稳定

Abstract: Slope wind is a dissipative structure, The thermodynamical instablizing conditions of slope wind is discussed, The critical Re is given to judge the thermodynamical instability of slope wind.

Key words: Slope wind, dissipative structure, thermody-namical instability
