Abstract

The results of a series of experiments with 12 acoustic computer-controllable sensors are reported in this paper. The experiments were conducted to study in detail the turbulence structure of low atmospheric layers. The measurements were accumulated at different schemes of the ultrasonic sensors spatial arrangement in horizontal and vertical planes. Based on the measurements obtained, the third and the fourth moment of wind velocity components and temperature fluctuations are considered. The dependence of skewness and kurtosis for a different of values measured at spatially separated point on the distance between the measurement points is obtained.
