| Abstract: | The mechanisms of formation of atmospheric irregularities (AI) by the solar terminator (ST) have been considered. All of these mechanisms are divided into two classes, linear or nonlinear, according to the mechanism of AI generation. All mechanisms determined by a moving step of some atmospheric parameter (pressure, temperature, and so on) belong to linear mechanisms for wave excitation. Mechanisms determined by instabilities in the atmosphere inside the ST region are nonlinear mechanisms. Examples are the gradient-radiatioe instability (GRI), which arises from the vertically inhomogeneous absorption of solar radiation, turbulence arising in the ST region, and the plasma instability in the evening hours caused by the increase of the electron pressure gradient inside the ST region. |
