Abstract. The present paper studies the perturbations in equatorial ionization anomaly (EIA) region during the Southern Hemisphere (SH) sudden stratospheric warming (SSW) of 2002, using the location of EIA crests derived from Global Positioning System (GPS) station observations and the Total Electron Content (TEC) obtained by International GNSS Service (IGS) global ionospheric TEC map (GIMs) in Asian sector. A strong quasi 10-day periodic oscillation is clearly identified in EIA region, and it has in-phase relationship between northern and southern EIA crests. An eastward phase progression of quasi 10-day wave is also seen in polar stratospheric temperature during this period, suggesting the enhanced quasi-10-day planetary wave associated with SSW produced oscillation in EIA region through modulating the equatorial fountain effect. Our results reveal some newer features of ionospheric variation that have not been reported during Northern Hemisphere (SH) SSWs.
