From: Evidence of short spatial variability of the equatorial electrojet at close longitudinal separation
The observed variability in EEJ strength between the two longitudes during D-season. Graph showing the differences in noontime peak values of EEJ strength between VEN and CBY, sorted on the basis of the daily mean of planetary index (Kp), i.e., Kp < 1 (a), Kp < 2 (b), and Kp > 2 (c) for the months November 2011 to February 2012. Black color represents the number of days with higher amplitudes for CBY > VEN and gray color for VEN > CBY.
