Atmosphere, 2020 This work presents the characteristics of gravity waves observed over Comandante Ferraz Antarctic Station (EACF: 62.1° S, 58.4° W). A total of 122 gravity waves were observed in 34 nights from March to October 2017, and their parameters were obtained by ...

Tamkang Journal of Mathematics, 1998 We are concerned with the steady wave motions in a 2-fluid system with constant densities. This is a free boundary problem in which the lighter fluid is bounded above by a free surface and is separated from the heavier one down below by an interface. By using a contractive mapping principle type argument.

Earth, Planets and Space, 2019 The reason for stationary gravity waves at Venus’ cloud top to appear mostly at low latitudes in the afternoon is not understood. Since a neutral layer exists in the lower part of the cloud layer, the waves should be affected by the neutral layer before ...

Satellite observations of middle atmosphere gravity wave absolute momentum flux and of its vertical gradient during recent stratospheric warmings [PDF]
Atmospheric Chemistry and Physics, 2016 Sudden stratospheric warmings (SSWs) are circulation anomalies in the polar region during winter. They mostly occur in the Northern Hemisphere and affect also surface weather and climate.

On the Separation Period Discriminating Gravity and Infragravity Waves off Gyeongpo Beach, Korea
Journal of Marine Science and Engineering, 2020 Although there have been a number of studies investigating fundamental characteristics of infragravity waves in coastal zones, a proper method of deciding period ranges that are associated with gravity or infragravity waves remains uncertain.

Relationship between ionospheric plasma bubble occurrence and lightning strikes over the Amazon region [PDF]
Annales Geophysicae, 2018 The vertical coupling between the troposphere and the ionosphere presents some remarkable features. Under intense tropospheric convection, gravity waves may be generated, and once they reach the ionosphere, these waves may seed instabilities and ...

The Astrophysical Journal, 1994 It is suggested that gravity waves could, in several cases, be detected by means of already (or shortly to be) available technology, independently of current efforts of detection. The present is a follow-up on a recently suggested detection strategy based on gravity-wave-induced deviations of null geodesics.

Characteristics of equatorial gravity waves derived from mesospheric airglow imaging observations [PDF]
Annales Geophysicae, 2009 We present the characteristics of small-scale (<100 km) gravity waves in the equatorial mesopause region derived from OH airglow imaging observations at Kototabang (100.3° E, 0.2° S), Indonesia, from 2002 to 2005.

Gravity wave activities in Tibet observed by COSMIC GPS radio occultation
Geodesy and Geodynamics, 2018 The Gravity waves activities in the Tibetan Plateau are very complex with different effects and natures that are not clear due to the lack of high resolution data from space and also from ground. In this paper, using COSMICGPS radio occultation data from
