A description is given of an apparently anomalous wind in the thermosphere that occurred near the time of an intense geomagnetic storm. The circulation was very strong and showed a linear increase with height. Although no causative relationship is proven, certain qualitative aspects of the wind direction and its variation with height indicate reasonable agreement with a suggested model.
A sequence of four vapor‐trail wind observations taken over a 6‐hour period above Kauai, Hawaii, is presented. The wind observations, covering part or all of the 90‐ to 180‐km region, are shown, because they so closely corroborate specific features documented by other vapor‐trail experiments at other locations. These features include the rotation of direction with height, vertical wavelengths of proper magnitude, and downward phase propagation with time. These features are consistent with results expected from the motion of upward propagating waves. The wave period appears to be semidiurnal, but a diurnal period is not excluded.
Summary. Semi-monthly mean sea-level pressure maps for the NIediterranean and adjacent areas are presented. Isobars have been drawn at 1-millibar intervals. The most significant features on the maps and the advantages of the mode of presentation are discussed briefly. Rgsum4.
