A statistical analysis of a vast global experimental material of irregularity ionization horizontal drift radio physical measurements at ionospheric levels up to 130 km allows one to reveal the basic features of the dynamical regime of the lower thermosphere. Intercalibration of radiomethods by simultaneous rocket and radio meteor measurements and physical considerations allow the measurements to be interpreted as an information on the neutral wind in the radio wave reflection region. In the mid-latitude ionospheric E-region the prevailing wind has a clearly pronounced seasonal variation in contrast to equatorial and high-latitude zone. In the high-latitude E-region there is observed an independent circulation cell probably linked with the properties of the thermal regime in the polar lower thermosphere. The drift measurements for 85-95 km by the method of spaced receivers in the long waveband in Eastern Siberia are reported for [1974][1975][1976]. The results are compared with simultaneous similar measurements at the same latitudes in Central Europe. The differences which are thought to be associated with climatic conditions at the observation sites, are emphasized.

We have carried out a statistical analysis of a huge array of archival experimental data on the dynamic regime of the ionosphere over Irkutsk, obtained by a radiophysical spaced-receiver method with a small base of a radio signal reflected from the ionosphere during vertical ground-based radio sounding near Irkutsk in 1958–1982. Statistical long-term characteristics of drifts of ionization irregularities over the region of the south of Eastern Siberia were obtained. We confirmed clear differences in the nature of the dynamic regime of the lower and upper ionosphere. The motion of ionization in the zonal direction is shown to be more regular than the meridional drift. We determined the characteristic seasonal features of variations in magnitudes and directions of horizontal drift motions at heights of E and F ionospheric regions. The lower ionosphere is characterized by high variability and seasonal variations in motion velocities. In winter, the zonal component of the horizontal ionization drift velocity is directed to the west; in summer, to the east. At the heights of the upper ionosphere, the dynamic regime is more regular. The prevailing zonal direction of the motion of ionization irregularities to the west is observed for all seasons (heights above 230 km). The meridional component of the horizontal drift velocity mainly has a southerly direction. Thus, the horizontal drift of plasma irregularities at the heights of the upper ionosphere is, on the whole, directed to the southwest with the zonal direction predominating.
