Fig. 3From: Effects of pre-reversal enhancement of E × B drift on the latitudinal extension of plasma bubble in Southeast AsiaRelations between maximum latitudes of scintillation for group 1 and a peak h’F, b maximum upward E × B drift, c duration of PRE and d the integral of upward E × B drift. Data for group 1 were obtained from the Chumphon ionosonde and the GPS receivers at Kototabang and Bandung. The y-axis in the right side in each panel indicates magnetic latitude at geographic longitude 99.4°E. Red lines indicate the linear relation between the two parameters in each panelBack to article page
