Abstract

The coherence of sonic waves at short paths in the atmospheric surface layer is analyzed. The violation of coherence is considered from the viewpoint of variations of phase difference in spatially separated observation sites. The statistics of phase difference at the multichannel reception of signals and its correlation with the statistics of the wind field are studied. Meteorological conditions at the sound propagation path were monitored by ultrasonic anemometersthermometers.
