Abstract
In the paper, we consider the results of analysis of structure functions of wind velocity components in the surface air layer over inhomogeneous underlying surface. Based on processing of experimental data, we singled out three basic types of structure functions and suggested analytical models for their approximation in the range of shifts, referring to inertial turbulence interval. The frequency of occurrence of the identified types of structure functions at different observation sites is estimated, and the statistics of the parameters of approximating functions is considered.
