Abstract:
We present the results of statistical processing of the envelope of a narrow-band sonic signal received with an acoustic meteorological radar (sodar). Hypotheses on the distribution law of the envelope at different altitudes under different geophysical conditions were checked. It was found that under convective conditions, experimental histograms in the lower part of the atmospheric boundary layer are best described by the gamma distribution and those in its upper layers - by the lognormal distribution. Under conditions of stable stratification, the envelope most often obeys the gamma distribution. No regularities were found in the distribution of the external (acoustic) noise.
