In two summertime mesoscale convective systems (MCSs), mesospheric optical sprite phenomena were often coincident with both large-amplitude positive cloud-to-ground lightning and transient Schumann resonance excitations of the entire Earth-ionosphere cavity. These observations, together with earlier studies of MCS electrification, suggest that sprites are triggered when the rapid removal of large quantities of positive charge from an areally extensive charge layer stresses the mesosphere to… 

Characteristics of Thunderstorms and Lightning Flashes Which Produce Mesospheric Transient Luminous Events

Space Dynamics Lab, EL241, Utah State University, Logan, Utah 84322 USAABSTRACT: A six year record of optical observations of lightning-induced mesospheric transient luminous events(TLEs) is

On ELF pulses from remote lightnings triggering sprites

ELF waveforms at large distances from strong CG (cloud‐to‐ground) discharges are evaluated in the framework of Greifinger's night‐time propagation model. It is shown that if the CG discharges

Sprites triggered by negative lightning discharges

High altitude air breakdown, manifested as “red sprites,” is reported in close association with negative cloud‐to‐ground lightning (−CG) on at least two occasions above an unusual storm on August 29,

SUPERCELLS AND SPRITES

Abstract Over a decade of monitoring mesospheric transient luminous events (TLEs) above U.S. high plains storms confirmed sprites are almost exclusively associated with positive polarity

Evidence for continuing current in sprite‐producing cloud‐to‐ground lightning

Radio atmospherics launched by sprite-producing positive cloud-to-ground lightning flashes and observed at Palmer Station, Antarctica, exhibit large ELF slow tails following the initial VLF portion,

Observations of Western Mediterranean TLE: LS8000 intracloud lightning and high-speed video

Transient luminous events (TLE) are electrical phenomena occurring between the ionosphere and the tops of thunderstorms. First discovered in 1989, the family of TLE now consists of different

Elves triggered by positive and negative lightning discharges

Optical flashes in the lower ionosphere due to the transient heating caused by lightning electromagnetic pulses (EMP) are unambiguously identified with the Fly's Eye photometric array. Data from a
