The degree of Doppler effect on the result in “numerical calculation in waveforms in the magnetic fields B caused by the subsequent vertical lightning return strokes to grounded tall structures of downward and upward flashes and the first vertical lightning return strokes to grounded tall structures of upward flashes 0.25/100 μs 50 kA in peaks on conventional methods” is evaluated in trial. The “velocity of the vertical lightning return strokes to grounded tall structures v 1.36 × 10 8 m/s”, “height on bottoms of lightning cloud H 1800 m”, “height at lightning points on tops of grounded tall structures Hi 200 m” and “evaluation points horizontally from channels of the vertical lightning return strokes to grounded tall structures 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 “numerical calculation in waveforms in the magnetic fields B caused by the vertical lightning return strokes to grounded tall structures 0.25/100 μs 50 kA in peaks on conventional methods”.
Keywords: Doppler effect, velocity of lightning return strokes to the earth, geometric treatment, numerical calculation, magnetic fields, intrinsic dynamic conductive current density, subsequent lightning return strokes to the earth of downward flashes, subsequent lightning return strokes to the earth of upward flashes, the first lightning return strokes to the earth of upward flashes
