In several papers, the solar cycle (SC) effect in the lower atmosphere has been linked observationally to the Quasi-biennial Oscillation (QBO) of the zonal circulation. Salby and Callaghan (2000) in particular analyzed the QBO wind measurements, c

At high latitudes in the upper mesosphere, horizontal wind oscillations have been observed with periods around 10h. Waves with such a period are generated in our Numerical Spectral Model (NSM), and they are identified as planetary-scale inertio gr

The Numerical Spectral Model (NSM) extends from the ground into the thermosphere and incorporates Hines' Doppler Spread Parameterization for small-scale gravity waves (GWs). In the present version of the model we account for a tropospheric heat so

Observations of the H3+ infrared emission at 2 and 4 μm have suggested that H3+ is in local thermodynamic equilibrium (LTE) in the region of the Jovian ionosphere from which the emissions originate. We have tested this assumption by calculating the

Relativistic electron and proton impact cross sections are obtained and represented by analytic forms which span the energy range from threshold to 109 eV. For ionization processes, the Massey–Mohr continuum generalized oscillator strength surface

Monte Carlo (MC) and continuous slowing‐down approximation (CSDA) calculations of proton energy deposition are compared for the same set of detailed atomic cross sections (DACS). It is found that the MC and CSDA results for the gross features of en

Spectral analysis of the midnight temperature anomaly observed on Atmosphere Explorer-E indicates that the phenomenon can be adequately represented with wave numbers between 1 and 5. Results from a multiconstituent circulation model suggest that this

Although the experimental observations of airglow intensity fluctuations and their possible connections with traveling ionospheric disturbances have been made by many investigators, very little attention has been given to a theoretical analysis of su

Using a discrete‐energy‐bin energy‐apportionment method in conjunction with a detailed atomic cross‐section approach, we obtain the degradation spectrum of H2 for a range of nonrelativistic incident‐electron energies extending from threshol
