dc.description.abstract	In an attempt to make synoptic observations of winds in the mesosphere and lower thermosphere, a simplified version of the correlation method for analysing spaced receiver ionosphere drift observations was developed. The new method makes possible the use of much simpler recording methods and eliminates the manual reduction of records. Drift observations made at noon between altitudes of 65 and 100 km, for summer 1963-4 and winter 1964 are presented. It is concluded that the mean monthly drift is a good estimate of the winds at these heights. The most prominent feature of the seasonal circulation is the upward progression of the height of reversal from westerlies (below) to easterlies (above) from 80 km in April to 100 km in July. The reversal height falls to 90 km in August and September.	en
