Time-series plots of a line-of-site northward velocity, b line-of-site northward velocity mapped onto the Southern Hemisphere, and c detrended TEC with time interval from 07:50 to 09:50 UT on 15 January. These values are averaged within the number of range gate from 14 to 18. The two red dotted lines indicate the time of the peak values of two TEC variations with relatively large amplitude
