A continuous vibration that produces a pleasant musical sound in low and high tones has been detected in the Earth’s atmosphere by scientists from the University of Kyoto and the University of Hawaii, who, in a publication in the Journal of the Atmospheric Sciences, confirmed theories developed in the last centuries.
The composition takes place in the form of large-scale atmospheric pressure waves that circle the globe, traveling through Ecuador both in the direction of East-West and West to East. Unfortunately, it is not possible to hear them, but each of these waves is analogous to one of the resonating sounds of a bell.

Since the beginning of the 19th century, researchers have been suspicious of this type of phenomenon, with the French physicist and mathematician Pierre-Simon Laplace being the first to suggest the hypothesis. The idea, then, has been refined over time, leading to detailed predictions of occurrences – without, however, reaching confirmation. Now, everything has changed.
Symphony of nature
Takatoshi Sakazaki, assistant professor at Kyoto University School of Science, and Kevin Hamilton, professor emeritus at the Department of Atmospheric Sciences and the University of Hawaii International Pacific Research Center, presented in their study an in-depth analysis of atmospheric pressure observed on the planet every hour for 38 years, revealing the presence of dozens of wave modes already imagined.
Focusing particularly on demonstrations with periods between two and 33 hours that travel horizontally and move at great speeds (more than 1,100 km / h), a pattern of high and low pressure was defined, associated with their propagation, similar to that of a water tray. Checkers. Still, the work has not been completed.

“The identification of so many modes in real data attests that the atmosphere really rings like a bell. This finally solves an old and classic problem in Science, but it also opens up a new research perspective to understand the processes that excite waves and those that act to dampen them ”, explains Kevin Hamilton.
In any case, Sakazaki sees plenty of reasons to celebrate in his achievement: “It is incredible to see the full validation of Laplace’s theory and other pioneering physicists after two centuries.”
