a CVW velocity versus universal time (UT) and magnetic latitude (MLAT) on 17 March 2013 between 1150 and 1340 UT and slant ranges 1035–1665 km. The propagation of SAPS Wavy Structure (SAPSWS) 1–4 is shown by yellow lines. The range coincident with Ionospheric Pierce Point (IPP) at 450 km between PRN 21 and Beaver Cove (BCOV) is shown by the pink line. b CVW velocity at IPP. The four periods with velocities < − 500 m s−1 are highlighted. c GPS TEC measurements at IPP. d Wavelet spectrum of CVW velocity at IPP. e Wavelet spectrum of GPS TEC. The colored dots show the three highest peaks for each spectrum. Reproduced from Fig. 3 of Makarevich and Bristow (2014)
