Fig. 2

Time series of the zonal (solid) and meridional (dashed) components of the mean FPI-measured wind. Colors from blue to red represent the upper limit of the SME applied to the mean wind calculation, which is incremented from 30 to 200 nT by 10 nT as depicted by a color scale in the figure. Magnetic local time (MLT) is labeled at the top bar
