⚡️Schumann Resonance Today⚡️
Black vertical bars indicate no data (lack of data registration for some reason).
The sonogram shows very clearly the natural and man-made electromagnetic background. Natural refers to the background created by lightning discharges located both in the vicinity (local thunderstorm) and in the distance located at distances of several hundred, thousand or tens of thousands of kilometers (atmospheres).
R. Yu. Petelin in his work «Virtual sound studio MAGIX Samplitude Pro X» (2012) noted that there is one area of analysis of signal properties in which the sonogram is simply irreplaceable — search for impulse noise. In the place where there is some kind of isolated ejection on the sonogram, there is most likely a click. In our case, this release manifests itself in the form of vertical stripes of increased level, i.e. white, and is associated with a local thunderstorm. The click is a local thunderstorm discharge.
The electromagnetic signal from lightning discharges in the far zone is called the atmosphere (the name comes from atmospheric electricity). Atmospheres that go around the Earth several dozen times until they fade out form Schumann resonances.
Technogenic electromagnetic background appears on the sonogram in the form of horizontal narrowband high-quality signals. This background is associated with operation and radiation from closely spaced power lines, transformer substations, and various mechanisms capable of emitting electromagnetic waves in the low-pass range.
Therefore in the sonogram we see Schuman resonances, local thunderstorms and man-made sources of electromagnetic radiation in the frequency range up to 40 Hz.
