The “result of development” and “example on result of calculation (only for extremely far electric fields E and magnetic fields B)” on the “simple calculation methods on waveforms of plane wave elements in the far and extremely far electric fields E and magnetic fields B close to the ground caused by the first vertical lightning return strokes to grounded large objects of downward flashes” which are able to be drawn the “result of calculation” also separately for “sources almost at particular points (starting points, lightning points, grounding points and points on bottoms of lightning cloud) along the vertical lightning return strokes to grounded large objects” are reported. The reduction on calculation time in the waveforms of the plane wave elements due to the simplification is tremendous.

Keywords: plane waves, far and extremely far electric fields, far and extremely far magnetic fields, conductive currents, the first lightning return strokes to the earth, downward flashes, time delay, velocity of lightning return strokes to the earth, the special theory of relativity, Doppler effect
