This propagating sudden brightening or darkening of the nightglow followed by a train of waves is called the mesospheric bore. This phenomenon occurs at ~90 km high. Its associated with the hydraulic jump of the airglow layer. Scientists speculate that this phenomenon is caused by atmospheric gravity waves trapped inside a temperature inversion layer.” Dr. Yue Jia, a research scientist at Hampton University, University of Maryland College Park and NASA Goddard Space Flight Center explained.
The Attached photo shows the similar phenomenon which was seen from the satellite, by Suomi NPP VIIRS Day Night Band.
There maybe more update in the coming days. As scientists from NASA and Chinese Academy of Science will check the data from S-NPP DNB Satalite and All sky airglow
