Role of gravity wavelike seed perturbations on the triggering of ESF – a case study from unique dayglow observations

First observational evidence, from the Indian longitudes, for the presence of gravity wavelike perturbations with periods of 20–30 min, acting as probable seeds for Equatorial Spread F (ESF) irregularities is described. The study is based on the daytime optical measurements of the mesopause temp...
