Abstract: Investigations on sprites and elves glow and a comparison of the observational work obtained at various locations by different workers are reported in this review. As the characteristic of these extraordinary phenomena is not yet well understood, an interpretation of the results is attempted from both experimental and theoretical points of view. The paper critically considers the latitudinal variations of lightning characteristics, as lightning flashes have a reported good relationship with the concerned unusual sprites and elves glow. It also discusses temporal variations of electron density, which is highly relevant as the extraordinary glow experienced between the cloud tops and the ionosphere. Subsequently, the sprites and elves associated sferics data in conjunction with electric and magnetic fields have been studied and the role of quasi-electrostatic thundercloud fields have been critically examined to focus this mysterious mesospheric glow.
