This brief introductory review of some recent developments in atmosphere–ionosphere
science is written for the “Vertical Coupling Special Issue” that is motivated by the 5th …

We report the first lidar observations of neutral Fe layers with gravity wave signatures in the
thermosphere from 110–155 km at McMurdo, Antarctica in May 2011. The thermospheric Fe …

Vertical shears of horizontal winds play an important role in the dynamics of the upper
atmosphere. Prior observations have indicated that these shears predominantly occur in the …

We derive the high‐frequency, compressible, dissipative dispersion and polarization
relations for linear acoustic‐gravity waves (GWs) and acoustic waves (AWs) in a single …

Using a global atmosphere‐ionosphere coupled model, the characteristics and excitation
source of traveling ionospheric disturbances (TIDs) during geomagnetically quiet periods …

We report on the electron density perturbation amplitudes, periods (up to 60 min), horizontal
and vertical wavelengths, phase speeds, and propagation directions of daytime traveling …

The mesospheric polar vortex (MPV) plays a critical role in coupling the atmosphere-
ionosphere system, so its accurate simulation is imperative for robust predictions of the …

With a thermosphere‐ionosphere Fe/Fe+ (TIFe) model developed from first principles at the
University of Colorado, we present the first quantitative investigation of formation …

In this paper, we derive the atmospheric gravity waves (GWs) and acoustic waves excited by
an ocean surface wave packet with frequency ωF and duration χ in an f plane, isothermal …

Contemporary theory, modeling, and first‐principles simulations indicate that dissipation of
gravity waves (GW) plays an important role in modifying the mean circulation, thermal …
