Sažetak

The aim of this numerical study is to evaluate several formulations of universal stability functions, which characterise turbulent exchange processes in the surface layer in the simple one-dimensional and two-dimensional numerical models. In the first part of the paper the one-dimensional prognostic model illustrates the basic behaviour of the stability functions and in the second part, the ability of the mentioned functions to provide a physical and numerical successful two-dimensional integration of the urban heat island circulation is examined. The results show that the examined formulations did not succeed in describing the development of the urban heat island circulation.
