Damping of the tides occurs primarily in the lower thermosphere region, and may be caused by turbulence from breaking gravity waves. A similar phenomenon to ocean waves breaking on a beach, the energy dissipates into the background atmosphere. Molecular diffusion also becomes increasingly important at higher levels in the lower thermosphere as the mean free path increases in the rarefied atmosphere.

Calculation of the lunar diurnal atmospheric tide. Full Record; Other Related Research; Authors: Geller, M A; Schoeberl, M R An ionospheric model is a mathematical description of the ionosphere as a function of location, altitude, day of year, phase of the sunspot cycle and geomagnetic activity. Geophysically, the state of the ionospheric plasma may be described by four parameters: electron density, electron and ion temperature and, since several species of ions are present, ionic composition. Radio propagation depends uniquely on electron density. crystaldiskinfo win11

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. crystaldiskinfo windows 11 download

"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. " - Ionospheric tide
