摘要：
An acoustic sensor has been developed for measuring the velocity circulation along a square contour of 6 cm size. Measurements of the circulation spectra at heights of 1-5 m in the atmospheric surface layer have demonstrated that the spectra depend on both stratification parameter and the orientation of the contour. The spectra measured are compared with those calculated for an isotropic velocity field. The problem of measuring vorticity fluxes using this device is discussed.
