A Numerical Simulation Research of Nocturnal Atmosphere Boundary Layer over Gobi

Abstract

Abstract: The development and structure of the nocturnal atmosphere boundary layer over Gobi are studied using one dimensional numerical model. Typical 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.

Key words: Gobi surface, atmosphere boundary layer, numerical simulation
