Monitoring Infrasound Background at the KB IZMIRAN Observatory

The data of field measurements of infrasound and acoustic–gravity waves in the observatory of the Kaliningrad Branch of the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation, Russian Academy of Sciences (KB IZMIRAN), located on the shore of the Vistula Lagoon, are presented. It is established that the main factors determining the infrasound background in the observatory are wind turbulence and wind waves from oscillatory movements of the water surface conjugated into a single circulation system. Estimates of the infrasound background level in different frequency ranges from wind turbulence and wind waves are obtained.
