Abstract

A new hardware-software ultrasonic complex AMK-03-4 is created for measurements of the characteristics of turbulent weather fields. In contrast to similar measuring instruments, the complex consists of four identical ultrasonic anemometers. This design allows recording not only turbulent, but also statistical characteristics of spatial derivatives of turbulent fluctuations of temperature and orthogonal wind speed components along the Cartesian axes, which makes possible the study of the spatiotemporal structure of turbulent meteorological fields of a surface air layer for subsequent application of the results in the similarity theory. The standard algorithm for calculation of structure parameters of fluctuations of temperature and wind velocity used in ultrasonic anemometers is improved, which provides for significantly lower measurement errors.
