Wind Influence on the Acoustic Gravity Waves Characteristics in the Polar Ionosphere

A. K. Fedorenko, Y. I. Kryuchkov


The wind influence on the acoustic gravity wave (AGW) propagation and characteristics is investigated in the polar thermosphere using the Dynamics Explorer 2 satellite data. The effects indicating the wind control of the AGW behavior are revealed: AGW and wind are systematically propagating in the opposite directions; the stronger the wind velocity, the larger the wave amplitude. The empirical dependence of wave amplitudes on the wind velocity is proved. Observed spectral peculiarities of the waves above the polar caps are determined by their modification in strong winds of polar circulation.
