Tones are caused by immense pressure waves that circulate the globe. Idea was first proposed by French physicist Pierre-Simon Laplace in the 19th century
A study conducted by an international team of scientists was able to detect the movement of a series of pressure waves that make the atmosphere of our planet vibrate like a bell: a fundamental lower tone, overlaid by several higher tones.
Atmospheric resonance was first proposed in the 19th century by French physicist Pierre-Simon Laplace, whose dynamic theory of the tides today allows scientists to predict deformations in a planet’s atmosphere.
According to Kevin Hamilton, professor at the International Pacific Research Center at the University of Hawaii and co-author of the study, the tones, which are not audible, are created by immense pressure waves traveling across the globe, some from east to west, others in the opposite direction. Each wave corresponds to a resonant frequency.
The new study includes a detailed analysis of observations of atmospheric pressure over the past 38 years. The researchers found dozens of individual waves, which circle the planet as if in a checkered pattern.
“The observed frequencies and global patterns correspond very well to those theoretically predicted,” said Takatoshi Sakazaki, assistant professor at Kyoto University School of Science and lead author of the study.
“It is exciting to see the vision of Laplace and other pioneering physicists so fully validated after two centuries,” he said.
