Thermospheric responses to gravity waves: Influences of increasing viscosity and thermal diffusivity
Sharon L. Vadas,David C. Fritts +1 more
TL;DR: In this article, a gravity wave anelastic dispersion relation is derived that includes molecular viscosity and thermal diffusivity to explore the damping of high-frequency gravity waves in the thermosphere.
Journal ArticleDOI
Occurrence characteristics of plasma bubble derived from global ground‐based GPS receiver networks
TL;DR: In this article, the authors studied the physical characteristics of plasma bubble occurrence using ground-based GPS receiver networks from 2000 to 2006, and found that the occurrence was high and constant for a station whose height on the dip equator (HODE) was less than 700 km.
Journal ArticleDOI
On the enigma of day-to-day variability in equatorial spread F
TL;DR: In this article, the authors show that large-scale wave structure (LSWS) is a contributor to the long-standing enigma of day-to-day variability in equatorial spread F (ESF).
Journal ArticleDOI
Analysis of the seasonal variations of equatorial plasma bubble occurrence observed from Haleakala, Hawaii
TL;DR: In this paper, the authors analyzed 300 nights of airglow and GPS scintillation data collected between January 2002 and August 2003 (a period near solar maximum) from the Haleakala Volcano, Hawaii are analyzed to obtain the seasonal trends for the occurrence of equatorial plasma bubbles in the Pacific sector (203° E).

Local time dependent response of postsunset ESF during geomagnetic storms
S. Tulasi Ram,P. V. S. Rama Rao,D. S. V. V. D. Prasad,K. Niranjan,S. Gopi Krishna,R. Sridharan,Sudha Ravindran +6 more
TL;DR: In this paper, the authors report the results of a multi-instrumental (ground-based and space-borne) and multistation study on the development/inhibition of postsunset ESF during five moderate to intense geomagnetic storms occurred during the low and descending phase of the solar activity period, 2004-2006.

The ionospheric disturbance dynamo
M. Blanc,Arthur D. Richmond +1 more
TL;DR: In this article, a numerical simulation study of the thermospheric winds produced by auroral heating during magnetic storms, and of their global dynamo effects, establishes the main features of the ionospheric disturbance dynamo.
Journal ArticleDOI
Response of the thermosphere and ionosphere to geomagnetic storms
TL;DR: In this paper, four numerical simulations have been performed, at equinox, using a coupled thermosphere-ionosphere model, to illustrate the response of the upper atmosphere to geomagnetic storms.
Journal ArticleDOI
Effects of the vertical plasma drift velocity on the generation and evolution of equatorial spread F
TL;DR: In this paper, the authors used radar observations from the Jicamarca Observatory from 1968 to 1992 to study the effects of the F region vertical plasma drift velocity on the generation and evolution of equatorial spread F.

Radar and satellite global equatorial F-region vertical drift model
Ludger Scherliess,Bela G. Fejer +1 more
TL;DR: In this article, the authors present a global empirical model for the F region equatorial vertical drifts based on combined incoherent scatter radar observations at Jicamarca and Ion Drift Meter observations on board the Atmospheric Explorer E satellite.

On the seasonal response of the thermosphere and ionosphere to geomagnetic storms
TL;DR: In this paper, a three-dimensional model of the coupled thermosphere and ionosphere is used to explain the dependence of the midlatitude ionosphere response to geomagnetic storms.
