Triangulation of red sprites observed above a mesoscale convective system in North China

Synchronous globally observable ultrashort-period pulses

“…On the basis of the results, we have made an assumption that a source of the pulses under study can be electrical sprites caused by powerful thunderstorms at middle and low latitudes. Using the results obtained by Wang, et al in [2019] on spatial and temporal fixation of sprites in North China, we have confirmed that ultra-short-period pulses occur following the emergence of sprites. Thunderstorm activity, both local and global, is considered to be one of the main sources of excitation of the ionospheric Alfvén resonator (IAR), which plays an important role in coupling the ionosphere and the magnetosphere.…”

“…In this paper, we study properties of impulsive geomagnetic disturbances observed synchronously at induction magnetometer networks of the Institute of Solar-Terrestrial Physics (ISTP SB RAS) and Canadian stations of CARISMA project [Mann et al, 2008], (Figure 1). Using data from Russian stations, we perform a morphological analysis of pulses detected and assume that their source may be electrical sprites [Wang et al, 2019] caused by powerful thunderstorms at middle and low latitudes. The possibility of feeding IAR oscillations through the energy of pulses detected is discussed.…”

Remotely controlled observations of electro-optical upper atmospheric phenomena from Baja, Hungary

“…The appearance of sprites is triggered by intense positive cloud-to-ground (+CG) lightning strokes (van der Velde et al, 2014). Sprite events are known to appear at various distances behind the convective cores above the stratiform region of the thundercloud in the mature state of the thunderstorm (Soula et al, 2015;Bór et al, 2018;Wang et al, 2019). While the location of thundercloud cells of deep convection can be estimated and the extension of the stratiform cloud region can be guessed from satellite IR images, the most reliable sources of this information are weather radar composite images.…”
