The lower thermosphere wind regime from simultaneous observations over Euroasia (Collm, Dushanbe, Frunze)The circulation in the lower thermosphere as determined from the results of measurements in 1984 is considered. Ionospheric drift measurements were taken using the method of spaced reception in the long wave range. Other measurements were taken using the D2 method. Average daily values of wind velocity were used. Discontinuity of measurements ranged from a day to a week. Preliminary data were reduced to the common average height of 93 km with the help of vertical profiles of wind velocity components. The results of measurements of zonal and meridional wind velocity components are presented. Zonal circulation changes from westerly to easterly winds were observed in winter, in periods of spring time reversal and during stratomesospheric rises in temperature.
