Book excerpt: This report documents the equations, coefficient parameterizations, method of numerical solution, and results from a theoretical (numerical) model of atmospheric tidal oscillations from the surface to 400 km. The westerly, northerly, and vertical winds and temperature are governed by four second order partial differential equations derived from the perturbation fluid equations for momentum, continuity, thermal energy, and the ideal gas law applied to a spherical, rotating, viscous atmosphere with anisotropic ion drag. The equations represent perturbations about a basic atmospheric state with latitude- and height-dependent mean winds, temperature, and composition. Model parameterizations described include mean winds and temperatures, molecular and eddy viscosity and thermal conductivity, ion-neutral collision frequency for momentum transfer, and solar thermal and lunar gravitational forcing. Thermal excitation occurs via absorption of EUV and UV radiation in the thermosphere, H2O insolation absorption in the troposphere and lower stratosphere, and O3 insolation absorption in the mesosphere. Ion-neutral coupling provides an important semidiurnal momentum source in the F-region. In addition, extensive tabulations and figures representing numerical solutions of diurnal and semidiurnal temperatures and winds every 6 deg of latitude from the surface to 400 km are presented for equinox and solstice conditions.

Download or read book A Compendium of Theoretical Atmospheric Tidal Structures written by J. M. Forbes. This book was released on 1982. 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.
