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. It is approximately 1.7 m/sec square; 4. Atmospheric tides are global-scale periodic oscillations of the atmosphere. In many ways they are analogous to ocean tides. Atmospheric tides can be excited by: • The regular day–night cycle in the Sun's heating of the atmosphere (insolation) • The gravitational field pull of the Moon
