Figure 4From: Fast and ultrafast Kelvin wave modulations of the equatorial evening F region vertical drift and spread F development Wavelet power spectra of the zonal and meridional components of the MLT winds over Cariri. The winds measured by a SKiYMET radar at Cariri are plotted at 2-km interval from 88 km up to 98 km. Hourly averaged values were used in the analysis. All other specifications are the same as for Figure 3.Back to article page
