New study detects ringing of the global atmosphere

Researchers now want to ‘understand both the processes that excite the waves and the processes that act to damp the waves.’

A ringing bell vibrates simultaneously at a low-pitched fundamental tone and at many higher-pitched overtones, producing a pleasant musical sound, says

A recent study, just published in the Journal of the Atmospheric Sciences by scientists at Kyoto University and the University of Hawaii at Mānoa, shows that the Earth’s entire atmosphere vibrates in an analogous manner, in a striking confirmation of theories developed by physicists over the last two centuries.

In the case of the atmosphere, the “music” comes not as a sound we could hear, but in the form of large-scale waves of atmospheric pressure spanning the globe and traveling around the equator, some moving east-to-west and others west-to-east.

Each of these waves is a resonant vibration of the global atmosphere, analogous to one of the resonant pitches of a bell.

The basic understanding of these atmospheric resonances began with seminal insights at the beginning of the 19th century by one of history’s greatest scientists, the French physicist and mathematician Pierre-Simon Laplace.

Research by physicists over the subsequent two centuries refined the theory and led to detailed predictions of the wave frequencies that should be present in the atmosphere. However, the actual detection of such waves in the real world has lagged behind the theory.

Now in a new study by Takatoshi Sakazaki, an assistant professor at the Kyoto University Graduate School of Science, and Kevin Hamilton, an Emeritus Professor in the Department of Atmospheric Sciences and the International Pacific Research Center at the University of Hawaii at Mānoa, the authors present a detailed analysis of observed atmospheric pressure over the globe every hour for 38 years.

The results clearly revealed the presence of dozens of the predicted wave modes.

    Reblogged this on WeatherAction News and commented:

    The study focused particularly on waves with periods between 2 hours and 33 hours which travel horizontally through the atmosphere, moving around the globe at great speeds (exceeding 700 miles per hour). This sets up a characteristic “chequerboard” pattern of high and low pressure associated with these waves as they propagate


    Interesting study. Thanks OB.

    Note their reaction to finding L2. Telling for luminaries.

    It’s a fun subject for weather-level exploration with no impact on our understanding of aggregate climate. (The latter subsumes all infinite detail of the former.)

    Where they’re going to end up is 96 (a bunch of zero-sum stuff bouncing around inside 10% of the bigger picture — technicians’ stuff – e.g. to be assigned to civil servants — not for Pareto Principle people).

    Why hasn’t Trump released whatever’s classified on 96? Doesn’t matter. Religion will still be religion no matter what classified materials are released.

    Luminaries literally don’t need the details (which would only be used to leverage human psychology catastrophically) to see the bigger picture. The spin doctors are already creating too much fatal resonance by synchronizing components destructively.

    The only other comment I have is that the research article (not to be confused with its media coverage) is way too long. That’s a cultural problem: placing inordinate value on quantity over quality. It’s a brutal method that earns no respect from luminaries.

    You just watch: Corrupt powers will steadfastly ignore 96. That is ALL the information you need.
