Variations in Electron Content Ratio and Semi-thickness Ratio during LSA and MSA periods and some Cyclone Genesis Periods using COSMIC satellite observations

An Investigation into Height Variation of Ionospheric Signature Due To the Cyclonic Storm Formation Using COSMIC-RO Measurements

“…This phenomenon admits the result of our previous study reported in Mondal et al, 2014. But here, as it is displayed in Fig.…”

“…It was already reported in one of our previous studies (Mondal et al 2014) that during Cyclone Genesis Period (CGP) (Sharkov, 2012) Table 1. To curtail the effect of diurnal variability in the ionospheric signature to be detected, if any, we finally calculate daily weighted mean and standard deviation of each parameter using equation (2).…”

“…The main approach of this study is to address sensible variations of ionospheric signature at different height levels due to CS generation at the lower atmosphere which is the major difference from other studies ( Mondal et al 2014). To select the ionospheric disturbances which are most likely to be associated with the perturbation generated due to existence of low pressure system like, CSs, the correlative variations between IECs have been analyzed.…”

“…In general, decrease in OLR is associated with an enhanced activity of precipitation i.e. increasing cloud amount and releasing latent heat, whereas its increase is associated with decrease in cloud amount (Jin et (Mondal et al 2014) it has been reported by analysing the Electron Content ratio (ECR) that during Cyclone Genesis Period (CGP) Ne concentration in the bottom side ionosphere increased by significant amount which help to get lower ECR during CGP compared to normal period. However, lack of sufficient number of scientific resources about ionospheric precursor and/or post-cursor signature during this type of convective phenomenon, encourages us to give insight into investigating the delicate evolution in Ne concentration at different height levels.…”
