Mysterious, Modulated Continuous Oscillations of Air Pressure in Central Europe

A comparison of the spectra of many European barometers shows that, despite the large distances between the sensors, the air pressure changes in phase at certain very low frequencies. The period lengths of around 60 hours are not related to the length of the day and do not provide any information about the possible causes of these oscillations. Over a period of twenty years, constant amplitudes and phase modulations are measured at a few discrete frequencies.

Mysterious, Modulated Continuous Oscillations of Air Pressure in Central Europe

Ein Vergleich der Spektren vieler europäischer Barometer zeigt, dass sich der Luftdruck bei speziellen, sehr niedrigen Frequenzen trotz großer Abstände der Sensoren phasengleich ändert. Die Periodendauern von etwa 60 Stunden stehen in keiner Relation zur Tageslänge und liefern keine Hinweise auf mögliche Ursachen dieser Schwingungen. Während des Zeitraums von zwanzig Jahren misst man konstante Amplituden und Phasenmodulation mit wenigen diskreten Frequenzen.
