Second order statistical moments of new internal MHD wave in the ionospheric F region are investigated analytically by geometrical optics approximation. Degree of a curvature of a constant phase surface and the variance of an instant frequency measuring by experiment has been obtained for arbitrary correlation function of electron density fluctuations. Energy exchange between the internal wave and turbulent plasma flow is considered calculating the mean energy flux density in the first and second approximations. Numerical calculations are carrying out for both anisotropic Gaussian correlation function and power law-spectrum characterizing elongated plasma irregularities using experimental data of satellites and incoherent scatter radar observations.

“…The influence of curvature of the lines of force of the geomagnetic field, Rayleigh and ionic frictions on the magnetogradient planetary waves were investigated in [7,10]. Linear and nonlinear problems of propagation of these waves in the dissipative E-region of the ionosphere were solved in [11][12][13][14]. Below we will not take into account the effects of viscosity, compressibility and temperature stratification [3,15,16].…”

A problem of propagation of very long planetary waves in the upper atmosphere of the Earth is investigated. A new exact solution of the magnetohydrodynamics equations of the ionosphere in the spherical coordinate system is found taking into account the Earth's rotation and geomagnetic field. The general dispersion equation for the planetary waves in the E and F regions of the ionosphere is derived and propagation of these waves in weakly ionized ionospheric plasma are studied.

Effect of ion temperature on oblique propagation of large amplitude solitary kinetic Alfvén waves

View full text Add to dashboard Cite

The effect of ion temperature on the existence of large amplitude solitary kinetic Alfvén waves and double layers are investigated in a two-fluid model using Sagdeev’s pseudopotential technique. The ion temperature, obliqueness parameter, and the ratio of cyclotron frequency to ion frequency are found to play significant roles in the formation and the shape of solitary kinetic Alfvén waves and double layers. Hump-type solitary waves and dip-type double layers are also observed. Conditions for the existence of solitary waves and double layers are discussed.
