Fig. 8From: PC index as a proxy of the solar wind energy that entered into the magnetosphere: 2. Relation to the interplanetary electric field E KL before substorm onsetRelationships between the delay time ΔT and the mean growth rates dV X/dt (a), dB Z/dt (b), and dE KL/dt (c) based on the analysis of coordinated events. Thin vertical bars present the standard deviation (sd) of individual values ΔV X/ΔT, ΔB Z/ΔT, and ΔE KL/ΔT from their mean quantities in each ΔT group; thick vertical bars present the standard error of the mean quantity determinationBack to article page
