The evolution of North-South symmetry ionospheric total electron content enhancement region (IMAGE)
Caption
The total electron content (TEC) and thermospheric wind variation in the Asian sector during the nighttime of DOY 132 (May 11). The background color diagram is the TEC observation distribution. The magenta arrows are the thermospheric wind observed by the FPIs. The black arrows give the scale of the thermospheric wind. The figure shows that there is an abnormal TEC enhancement region in the northern and southern hemispheres moving westward, and the two enhancement regions are symmetrical in the northern and southern hemispheres under the control of dynamic processes.
