Joule heating and winds due to geomagnetic disturbances
TLDR
In this paper, a self-consistent theoretical model of the dynamical processes occurring in the Earth's upper atmosphere has been developed based on magnetohydrodynamic concepts, and the May 1967 geomagnetic storm data recorded at College, Alaska, have been used in the resulting set of non-linear, partial differential magnetodynamic equations, to calculate variations due to the storm in the amount of Joule heating and the winds at an altitude of approximately 140 km as a function of time.About:

Nighttime thermospheric winds at high latitudes
TL;DR: In this article, the authors used the Doppler shifts of the (0I) 15867 K (6300 A) line emission of Ester Dome, near College, Alaska, to obtain the characteristic nighttime behavior of both the zonal and the meridional neutral wind components at F-region heights.

Ion‐neutral momentum coupling near discrete high‐latitude ionospheric features
TL;DR: In this paper, a two-dimensional numerical model is developed to study the momentum coupling between the ionosphere and neutral atmosphere in the vicinity of discrete high-latitude features, such as convection channels and plasma density troughs.
Journal ArticleDOI
Dynamics of the thermosphere at high latitudes
TL;DR: In this paper, a review of both observational and theoretical investigations of the response of the neutral upper atmosphere to processes which are unique to high latitudes is presented, where the effects of viscosity, ion drag, the Coriolis force, thermal conduction, and solar extreme ultraviolet radiation (EUV) heating are considered.

Upper atmospheric response to transient heating
G. E. Thomas,B. K. Ching +1 more
TL;DR: In this paper, the response of the upper atmosphere to various forms of time-dependent heating is calculated by use of approximate analytic solutions of the heat conduction equation, and the desired model for polar substorm heating maximizes in the 140-to 160-km altitude region with an average duration of 4 to 5 hours.
