TL;DR: In this paper, the occurrence of Equatorial Counter Electrojets (CEJets) with a quasi 16-day periodicity over Trivandrum (8.5° N, 76.6° E, 0.5º N diplat) in association with the polar Stratospheric Sudden Warming (SSW) events is presented.

TL;DR: In this article, the variations of the mesopause temperature and the Equatorial electrojet strength over the dip equator during December 2005-March 2006 period were analyzed, indicating a possible strong dynamical coupling between the two regions through the intensification of planetary wave activity.

TL;DR: Vineeth et al. as discussed by the authors presented the first observations of lowering of mesopause temperature during counter electrojet (CEJ) events over a narrow region of ∼ ± 150 km centered at around magnetic equator.

TL;DR: In this article, the mesopause temperature and the intensity of the thermospheric O(1D) 630.0 nm dayglow emissions using the unique MultiWavelength Dayglow PhotoMeter from Trivandrum (8.5° N; 77° E; dip lat ~ 0.0° N), a dip equatorial station were used to detect gravity wave perturbations with periods of 20-30 min acting as probable seeds for Equatorial Spread F (ESF) irregularities.

TL;DR: In this paper, a reanalysis of the NCEP/NCAR re-analysis of stratospheric wind and temperatures of recent years clearly showed that the zero-wind line appears over the tropics ~60 days prior to the major SSWs and progresses towards the pole and an enhanced PW activity of quasi periodicity 16-days, which is also seen almost simultaneously with the zero wind line, shows a propagation from equator to the Pole.
