Abstract: The correlation between atmospheric gravity waves (GWs) and Transient Luminous Events (TLEs) has been poorly studied using both synchronous observations and numerical simulations. To investigate the modulation effects of GWs on TLEs, a troposphere-mesosphere quasi-electrostatic… read more here.

DOI: 10.1088/1402-4896/abdb58
Abstract: This study characterizes spatially varying optical emissions in a compact dipole plasma device driven at steady-state by continuous mode microwaves. The study is motivated by visual observations, which indicate a distinct pattern of alternate bright… read more here.
