The Institute of Experimental Meteorology carries out regular wind measurements by the meteor radar at three stations, Heiss Island (from 1964), Obninsk (from 1964) and Molodezhnaya, the Antarctica (from 1967). The seasonal course of wind regime parameters in the meteor zone in different years was found to be relatively stable in comparison with site-to-site variations of these parameters. It is shown that wind velocity variations with the periods from 2-5 to 10-20 days are typical of the meteor zone and are connected with corresponding variations in stratomesosphere. The analysis of dates for different years showed that in the meteor zone the spring reversal of circulation begins much earlier in stratosphere; more earlier (later) dates of the reversal in stratosphere correspond to more earlier (later) dates of the reversal beginning in the meteor zone.
