a wave record of 3.5 min long intervals (Andreev, 1988)
lence may possibly be connected with both pressure and wind speed fluctuations. It should be noted that the temporal scales of the micro-meteorological
spectral maximum in these atmospheric characteristics differ significantly. It
is the order of several tens of minutes for the pressure spectra and the order
of a minute for the wind speed. This quasi-oscillation period of wave spectrum parameters, as shown above, is correlated with the pressure fluctuation
of atmospheric turbulence.
