“…Discoveries of the transient luminous effects (TLE), such as elves, red sprites, and blue jets, possibly caused by the breakdown at altitudes ∼90 km, revealed the possibility of a much stronger lightning coupling to the ionosphere than previously deemed possible. These processes, associated with large high-altitude nonlinear currents, may strongly enhance the weight of the ULF-ELF spectrum in the lightning transients in the ionosphere, and the IAR excitation by strong lightning discharge (Sukhorukov and Stubbe, 1997). However, so far few attempts (e.g., Bösinger et al, 2006) to reveal any speci c ULF response to distant high-altitude TLE as compared with ordinary lightning were not successful.…”

ULF impulsive magnetic response at mid-latitudes to lightning activity

et al. 2011

Induction magnetometer data from the mid-latitude station Moshiri (geomagnetic latitude 35.6• ) has been examined in search of a transient ULF response to the regional lightning activity. For many events, besides the main impulse produced by the lightning discharge, a secondary impulse delayed about 1 sec was observed. These secondary echo-impulses are probably caused by the partial re ection of wave energy of the initial lightning pulse from the upper boundary of the ionospheric Alfven resonator in the topside ionosphere. The modeling with arti cial signals has shown that a multi-band spectral resonant structure (SRS) can be formed owing to the occurrence of paired pulses in analyzed time series. The statistical superposed epoch method indeed has revealed a dominance of two-pulse structure in the magnetic eld background during the periods of the SRS occurrence.

“…[25] Several natural mechanisms have been proposed regarding IAR excitation, including lightning [Surkov et al, 2006;Shalimov and Bösinger, 2008], transient luminous events, e.g., sprites [Sukhorukov and Stubbe, 1997], and ionospheric-magnetospheric plasma waves, e.g., geomagnetic pulsations [Lekhtinen et al, 1995;Lysak and Song, 2003]. The IAR artificial excitation has also been claimed by means of ULF-ELF transmitters that match the resonator frequency or by changing the macroscopic parameters of the ionosphere with radar pulses [Trakhtengertz et al, 2000].…”

Detection of ionospheric Alfvén resonator signatures in the equatorial ionosphere

.[1] The ionosphere response resulting from minimum solar activity during cycle 23/24 was unusual and offered unique opportunities for investigating space weather in the near-Earth environment. We report ultra low frequency electric field signatures related to the ionospheric Alfvén resonator detected by the Communications/Navigation Outage Forecasting System (C/NOFS) satellite in the equatorial region. These signatures are used to constrain ionospheric empirical models and offer a new approach for monitoring ionosphere dynamics and space weather phenomena, namely aeronomy processes, Alfvén wave propagation, and troposphere-ionosphere-magnetosphere coupling mechanisms.

“…Surkov et al (2006) introduce a theory of mid latitude IAR excitation showing that local lightning activity may explain the resonator excitation. Sukhorukov and Stubbe (1997) propose a mechanism to explain IAR excitation by strong lightning discharges followed by transient luminous events. Demekhov et al (2000) discuss a different approach involving Pc1 waves.…”

Dynamic Coupling Between Earth’s Atmospheric and Plasma Environments

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 2019-03-25T00:54:44+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.
