The influence of the irregular movements in the lower thermosphere on the ionospheric Es-Layer by radiometeor observations in Kazan (56°N, 49°E)

Abstract

Significant influence of diurnal and interdiurnal variations of irregular movements at heights of the lower thermosphere on the frequency parameters of ionospheric sporadic E-layer, characterizing its intensity, was found out. Common periodicities with time scales of planetary waves, having significant coherence, were revealed in variations of mesoscale turbulence intensity and critical frequency foEs, blanketing frequency fbEs. © 2001 Elsevier Science Ltd.
