By a News Reporter-Staff News Editor at Physics Week -- Current study results on Physics - Terrestrial Physics have been published. According to news originating from Trivandrum, India, by VerticalNews correspondents, research stated, “An analysis of Gravity wave induced travelling ionospheric disturbances (GW-TIDs) in the thermosphere during high and low solar epochs is undertaken using ionosonde data at Trivandrum (8.5(0)N, 77(0)E). Wavelet analysis is performed on the temporal variations of foF(2) and the amplitudes of waves present in two period bands of (0.5-1.5) h and (2-4) h are extracted.”
Financial support for this research came from Indian Space Research Organization, Govt. of India.
Our news journalists obtained a quote from the research, “The real height profiles are generated at 15 min internal for the whole day (for sample days) during high and low solar activity years. The study reveals that the GW-TID activity is significantly greater for solar minimum compared to solar maximum for the period 8.5-17.5 h. Diurnally the GW-TID activity in the (2-4) h period band peaks in the post sunset hours for both high and low solar epochs. For the 0.5-1.5 h period band, the diurnal maximum in GW-TID is occurring in the post sunset hours for high solar epoch while it occurs in the morning hours around 10 h LT for low solar epoch. Seasonally the day time GW-TID activity maximizes (minimizes) for winter (vernal equinox). The post sunset time GW-TID maximizes (minimizes) either for summer/winter (vernal equinox). The other interesting observation is the anti correlation of GW-TID in upper thermosphere with solar activity for day time and the correlation of the same with solar activity in the post sunset hours. The present results for daytime are in agreement with the equatorial daytime GW-TID behaviour reported from CHAMP satellite observations.”
According to the news editors, the research concluded: “The GW-TID activity during post sunset time for equatorial region upper thermosphere has not been reported so far.”
