“…Rees (1995) reviews observations and modeling of ionospheric and thermospheric disturbances during major geomagnetic storms. On the other hand, Lastovicka (1996) investigates effects of geomagnetic storms in the lower ionosphere, middle atmosphere, and troposphere. Frahm et al (1997) show that diffuse aurora is a significant source of ionization in the middle atmosphere because energetic electrons can cause excitation, dissociation, ionization, and heating of neutrals.…”

A Review of Low Frequency Electromagnetic Wave Phenomena Related to Tropospheric-Ionospheric Coupling Mechanisms

et al. 2011

Investigation of coupling mechanisms between the troposphere and the ionosphere requires a multidisciplinary approach involving several branches of atmospheric sciences, from meteorology, atmospheric chemistry, and fulminology to aeronomy, plasma physics, and space weather. In this work, we review low frequency electromagnetic wave propagation in the Earthionosphere cavity from a troposphere-ionosphere coupling perspective. We discuss electromagnetic wave generation, propagation, and resonance phenomena, considering atmospheric, ionospheric and magnetospheric sources, from lightning and transient luminous events at low altitude to Alfven waves and particle precipitation related to solar and magnetospheric processes. We review in situ ionospheric processes as well as surface and space weather phenomena that drive troposphere-ionosphere dynamics. Effects of aerosols, water vapor distribution, thermodynamic parameters, and cloud charge separation and electrification processes on atmospheric electricity and electromagnetic waves are reviewed. We also briefly revisit ionospheric irregularities such as spread-F and explosive spread-F, sporadic-E, traveling ionospheric disturbances, Trimpi effect, and hiss and plasma turbulence. Regarding the role of the lower boundary of the cavity, we review transient surface phenomena, including seismic activity, earthquakes, volcanic processes and dust electrification. The role of surface and https://ntrs.nasa.gov/search.jsp?R=20120011991 2018-05-12T18:35:14+00:00Z atmospheric gravity waves in ionospheric dynamics is also briefly addressed. We summarize analytical and numerical tools and techniques to model low frequency electromagnetic wave propagation and solving inverse problems and summarize in a final section a few challenging subjects that are important for a better understanding of tropospheric-ionospheric coupling mechanisms.

“…For instance, the review papers by Buonsanto (1999) and Prölss (1995) did not deal with them at all. Lastovicka (1996) reviewed in brief geomagnetic storm effects on the lower ionosphere, middle atmosphere and troposphere, and another review paper by Danilov and Lastovicka (2001) only briefly mentioned a few papers that had been dealing with geomagnetic storm effects at the F1 heights. Buresova and Lastovicka (2001) analyzed the effects of a few geomagnetic storms in electron density at F1 heights during daytime, based on data of three European ionosondes.…”

Daytime electron density at the F1-region in Europe during geomagnetic storms

et al. 2002

Abstract.This study attempts to demonstrate changes in the ionospheric F1-region daytime ionization during geomagnetic storms. The F1-region is explored using available data from several European middle latitude and lower latitude observatories and a set of geomagnetic storms encompassing a range of seasons and solar activity levels. The results of analysis suggest systematic seasonal and partly latitudinal differences in the F1-region response to geomagnetic storm. The pattern of the response of the F1-region at higher middle latitudes, a decrease in electron density, does not depend on the type of response of the F2-region and on solar activity. A brief interpretation of these findings is presented.

“…However, for individual storms it is necessary to be sure that ionospheric conditions and heights in the consideration are the same. Lastovicka and Kazimirovsky (1995) and Lastovicka (1996) summarized results on the geomagnetic storm/activity effects at high and middle latitudes. The existence of such effects at lower altitudes is questionable, if they occur at all.…”

Dynamical Climatology of the Upper Mesosphere, Lower Thermosphere and Ionosphere

2006

The main features of upper atmosphere dynamics as an important part of upper atmosphere climatology are presented. The dynamics of the mesosphere and lower thermosphere (MLT) are of special interest. The results are based on the long series of investigations in East Siberia and data from a world-wide network of observatories. We present the regional climatic norms for the prevailing wind and semi-diurnal tide and the main features of the quasi-periodic structure of the wind field. The non-zonality of MLT dynamics is demonstrated as well as regional differences in the response of the wind field to stratospheric disturbances, solar activity variations and geomagnetic storms.
