Fig. 8From: Daily and seasonal variations in the linear growth rate of the Rayleigh-Taylor instability in the ionosphere obtained with GAIAHistograms of the number of EPB occurrence/non-occurrence days for ΣKp. The histograms indicate the relationship between ΣKp (daily total of the Kp) and the number of days of EPB occurrence (red bars) and non-occurrence (blue bars) in a 2011, b 2012, and c 2013Back to article page
