Abstract: A program for automated streamline analysis is described based an ?optimum interpolation? techniques. Streamlines may be directly interpolated from irregularly timed and spaced wind observations. Smoothing of the wind ...

Abstract: Height-time sections of mean monthly observed upper-air zonal winds at stations within 20 degrees of the equator show not only an almost biennial oscillation of the wind in the middle or upper stratosphere but that there ...

Abstract: Daily data at 16 stations along five latitudes from 13°N. to 33°S. were carefully examined at the 50-, 100-, and 500-mb. levels for evidence of longitudinal phase progression of the quasi-biennial oscillation (QBO). At 50 ...

Abstract: The 10.7-cm solar radio flux is considered to be highly correlated with solar extreme ultraviolet radiation, thermospheric temperatures, sunspots, and the 27-day and 11-year solar cycles. To investigate the possibility of ...

Abstract: The observed variability patterns of monthly mean zonal winds over an 11-year period, from 80°N?70°S and from 20?65 km, are explained in terms of component patterns of a long-term mean, quasi-biennial, annual and semi-annual ...

Abstract: The mean and individual seasonal reversal progressions are described for each of the 11 years of available rocket observations from 80°N to 80°S, and from 20 to 65 km. Isochrone sections were based on the time sections of ...
