For many years physicists have carried out observations at the Antarctic station "McMurdo". Two years ago they found that in the higher layers of the Earth's atmosphere, every three or ten o'clock, the 2000-kilometer wave appears regularly. Subsequently, the researchers found another type of gravitational waves in the stratosphere with a length of 400 meters.
It is reported Phys.org
Professor of Aerospace Sciences, Sudha Chu said that the discovery of a new type of gravity waves will help to study in detail all models of atmospheric currents.
Professor Chu and his colleagues believe that a new type of gravitational wave in the stratosphere originates either from the lower-level waves that originate from currents near the mountain slopes or the polar whirlwind that occurs over the South Pole in winter.
Experts hope that these studies will help them better understand the relationships between layers of the Earth's atmosphere.

It is known that the understanding of the origins of waves was based on the theory of secondary gravitational waves of Sharon Vadas and global high-resolution models developed by Erich Becker at the Leibniz Institute for Physics in Germany. The Becker model is a combination of theory and lidar observations. This suggests that the formation of secondary waves is continuous, especially in winter, and that it occurs not only at the McMurdo station but in the middle and high latitudes of both hemispheres.
Note that the stratosphere is the layer of earth's atmosphere that protects the planet from ultraviolet radiation
The term "gravitational wave" was introduced in 1905, the French mathematician, mechanic, physicist, astronomer and philosopher Henri Poincaré.
Earlier, in the nineteenth century physicist, one of the founders of modern theoretical physics, Nobel Prize in Physics, 1921, Albert Einstein argued that due to technical difficulties, scientists were unable to register the measurement gravitational waves due to the required highly accurate measurement ,
