Available in PDF, EPUB and Kindle. Book excerpt: Solutions to the thermospheric tidal equations are described that define the extensions into the thermosphere of normalized wind and temperature structures associated with the (2,2), (2,3), (2,4), and (2,5) semidiurnal propagation tidal modes. The degree of alteration of vertical structures with latitude, and the change in horizontal shapes with height, corresponding to semi-diurnal oscillations in northerly, westerly, and vertical velocity, and to temperature in the thermosphere are examined and implications to modeling the thermosphere are discussed. Extensive figures and tables covering the 80-400 km altitude region for five levels of solar activity at 6 deg latitude increments are provided for potential users. The structures can be used to extend meteor wind (80-100 km) and partial reflection drift (60-100 km) measurements to above 100 km for consistency checks with tidal winds and temperatures from Thomson scatter measurements at possibly different latitudes, or to simultaneously fit data covering these height regions for modeling purposes.
