Abstract : In a recent study based on meteorological rocket wind measurements, the author reported a number of findings on the winds between 150,000 and 200,000 feet (see Introduction below). Using the additional data now available, the present paper carries the analysis up to 220,000 feet. It is shown that both the winter westerlies and summer easterlies reach their maximum intensity near the 200,000-foot level, above which they decrease. It was also found that the spring reversal from winter westerlies to summer easterlies begins above 220,000 feet and then proceeds downward; the autumn reversal from easterlies to westerlies, however, appears first near the 210,000-foot level, followed with a short lag by reversals at both higher and lower altitudes. The north-south component again proved relatively insignificant in comparison to the east-west component. (Author)
