Abstract:

A detailed derivation of the existing linearized atmospheric tidal theory is given. In comparison with the theory, experimental results are determined from wind data which were obtained from chemical release trails in the 90 to 120 km height region. The rocket wind data were analyzed by two methods 1 a geometrical method which was devised by using the physical properties of the wind motion under consideration, and 2 a generalized least squares procedure which was developed by G. V. Groves. Both analyses separated the prevailing, diurnal, and semidiurnal wind components from the total winds. In addition, an analysis was performed involving pairs of wind profiles which led to a profile of the irregular winds versus height in the height region near 100 km. Author
