WebTides and gravity waves have similar effects on ionization in the E region. They both are responsible for concentrating ionization in layers. In combination with the large-scale system of winds in the lower thermosphere, they are also effective in driving an irregular current that flows in the E and lower F regions of the ionosphere. WebDuring the night, the ionosphere has only the F and E layers. ... That is why we feel the tidal waves go high and low during full moon. so when the moon is near to earth the gravitational force od moon is felt high when compared to that of sun.

WebTravelling Ionospheric Disturbances (TID): TIDs are signatures of atmospheric gravity waves. The atmospheric waves cause perturbations in the winds and density of the thermosphere, which is impacting the electron density. Depletions: Electron density depletions in mid-latitudes often occur during high geomagnetic activity. WebAtmospheric tides are ubiquitous features of the Earth's atmosphere. They are the persistent global oscillations that are observed in all types of atmospheric fields, including wind, temperature, pressure, density, and geopotential height. Tidal oscillations have periods that are some integer fraction of a solar or lunar day.
