Observation and simulation of atmospheric gravity waves exciting subsequent tsunami along the coastline of Japan after Tonga explosion event [PDF]

Scientific Reports, 2022
Tsunamis are commonly generated by earthquakes beneath the ocean floor, volcanic eruptions, and landslides. The tsunami following the Tonga eruption of 2022 is believed to have been excited by atmospheric pressure fluctuations generated by the explosion ...

A review of atmospheric gravity waves and travelling ionospheric disturbances: 1982-1995 [PDF]

Annales Geophysicae, 1996
Recent investigations of atmospheric gravity waves (AGW) and travelling ionospheric disturbances (TID) in the Earth\'s thermosphere and ionosphere are reviewed. In the past decade, the generation of gravity waves at high latitudes and their subsequent

A case study of gravity waves in noctilucent clouds [PDF]

Annales Geophysicae, 2004
We present a case study of a noctilucent cloud (NLC) display appearing on 10-11 August 2000 over Northern Sweden. Clear wave structures were visible in the clouds and time-lapse photography was used to derive the parameters characterising the gravity ...

An Introduction to Atmospheric Gravity Waves

, 2012
Gravity waves exist in all types of geophysical fluids, such as lakes, oceans, and atmospheres. They play an important role in redistributing energy at disturbances, such as mountains or seamounts and they are routinely studied in meteorology and ...

Probing signals of atmospheric gravity waves excited by the July 29, 2021 MW8.2 Alaska earthquake

Geodesy and Geodynamics
It is commonly believed that the atmosphere is decoupled from the solid Earth. Thus, it is difficult for the seismic wave energy inside the Earth to propagate into the atmosphere, and atmospheric pressure wave signals excited by earthquakes are unlikely ...

The generation and propagation of atmospheric gravity waves observed during the Worldwide Atmospheric Gravity-wave Study (WAGS)

Journal of Atmospheric and Terrestrial Physics, 1988
Abstract During the Worldwide Atmospheric Gravity-wave Study (WAGS) in October 1985, the EISCAT incoherent scatter radar was used to observe the generation of atmospheric gravity waves in the auroral zone in conjunction with a network of magnetometers and riometers. At the same time a chain of five ionosondes, an HF-Doppler system, a meteor radar and

A new method for detecting solar atmospheric gravity waves. [PDF]

Philos Trans A Math Phys Eng Sci, 2021
Internal gravity waves have been observed in the Earth’s atmosphere and oceans, on Mars and Jupiter, and in the Sun’s atmosphere. Despite ample evidence for the existence of propagating gravity waves in the Sun’s atmosphere, we still do not have a full understanding of their characteristics and overall role for the dynamics and energetics of the solar ...

Object Recognition of Atmospheric Gravity Wave Based on Foundation Airglow Images [PDF]

Jisuanji gongcheng, 2023
With the construction of the Meridian Project all-sky airglow imager observation network, a large amount of raw airglow image data has been accumulated. The current atmospheric gravity wave research based on airglow observation is extremely dependent on ...

Intermittency of gravity wave potential energies and absolute momentum fluxes derived from infrared limb sounding satellite observations [PDF]

Atmospheric Chemistry and Physics, 2022
Atmospheric gravity waves contribute significantly to the driving of the global atmospheric circulation. Because of their small spatial scales, their effect on the circulation is usually parameterized in general circulation models.
