“…According to the dynamics of lightning channel corona sheath [e.g., Ignjatovic et al, 2014;Rakov, 2006, 2013;Cvetic et al, 2012], the lightning channel consists of a narrow current-carrying core surrounded by the external corona sheath, the external corona sheath is formed by the radial electric field created by the charge in the thin current-carrying core. Rakov and Uman [2003] and Rakov [1998] have reported that the bulk of the leader charge is stored in the corona sheath whose radius is of the order of meters, while the highly conductive channel core probably less than 1 cm in radius carries essentially all the longitudinal current.…”

Using high time‐resolved spectra and simultaneous records of the electric field change of three negative cloud‐to‐ground (CG) lightning flashes with multiple return strokes, the correlations between the total intensity of ionic lines in the spectra and the corresponding amplitude of the initial electric field change, as well as between the total intensity of the spectra and the channel apparent diameter, have been analyzed. The analysis shows the following: (1) The amplitude of the initial electric field change is roughly proportional to the total intensity of ionic lines. (2) The total intensity of the spectra shows a significant linear correlation with the apparent diameter of the channel. (3) The total intensity of ionic lines for 17 analyzed return strokes decreases with increasing height along the channel, which is consistent with the current variation along the channel in the modified transmission line model; the Master, Uman, Lin, and Standler model; and the Diendorfer‐Uman model. Meanwhile, the total intensity of ionic lines for other two analyzed return strokes along the channel without attenuation, this is consistent with the current variation along the channel in the Bruce‐Golde model, the transmission line model, and the Traveling Current Source model.

“…The lightning leader channel consists of a thin core surrounded by an external radially formed corona sheath [ Ignjatovic et al , ; Cvetic et al , ; Maslowski and Rakov , , ]. The charge in the thin channel core will create a radial electric field with the value in excess of the breakdown electric field.…”

Correlation between the spectral features and electric field changes for natural lightning return stroke followed by continuing current with M‐components

According to the high time‐resolved spectra of two first and a subsequent return strokes and the following continuing current processes overlapped with M‐components in three natural cloud‐to‐ground lightning, the correlation between the total intensity of ionic lines in the spectra and the corresponding amplitude of electric field change and that between the total intensity of the spectra and the apparent diameter of the discharge channel have been investigated. Linear correlations have been found for the above two sets of parameters. The luminous properties along the channel show that the total intensity of ionic lines in the spectra for both the return stroke and M‐components decreases with increasing height along the channel. The total intensity of the spectra and the apparent diameter for the return stroke also go down with increase of the height, while those for M‐components do the reverse.
