摘要
本文采用一维非定常边界层模式研究了戈壁下垫面夜间边界层的结构和发展规律。得到了戈壁下垫面夜间冷却条件下辐射逆温层的形成和发展以及下波风建立的典型时空图象。并与实测资料进行了比较。文中还对局地逆向流和地面降温率对辐射逆温层高度和下坡风的影响进行了试验。
In this paper,thedevelopment and structure of the nocturnal atmosphere boundary layer over Gobi are studied using one dimensional numerical model. Typi-cal features of the development and the formation of the inversion and the slope flow wind during nocturnal surface cooling condition are obtained. The simulation results are compared with the observational data and are in good agreement with ones.
