The degree of Doppler effect on the result in the “numerical calculation in waveforms in the electric fields E caused by the first vertical lightning return strokes to the flat ground of downward flashes 10/350 μs 200 kA in peaks on conventional methods” in Case 2 of possibilities is evaluated in trial. The “velocity of the first vertical lightning return strokes to the flat ground v 2.14 × 10 8 m/s”, “length on channels of the first vertical lightning return strokes to the flat ground H 1800 m”, “starting height of the first vertical lightning return strokes to the flat ground in lower parts in channels of the first vertical lightning return strokes Hi 630 m on Case 2 of possibilities”, “pulse grounding resistance of concentrated constants at lightning points of the first vertical lightning return strokes to the flat ground Rg 600 Ω” and “evaluation points horizontally from channels of the first vertical lightning return strokes to the flat ground D 10 m, 100 m, 1 km, 10 km and 100 km and vertically from the flat ground L 1.5 m, 10 m and 100 m” are selected as the condition on the “numerical calculation in waveforms in the electric fields E caused by the first vertical lightning return strokes to the flat ground of downward flashes 10/350 μs 200 kA in peaks on conventional methods” in the Case 2 of the possibilities.

Keywords: Doppler effect, velocity of lightning return strokes to the earth, geometric treatment, numerical calculation, electric fields, intrinsic dynamic volume charge density, intrinsic dynamic conductive current density, the first lightning return strokes to the earth of downward flashes
