基于二维时域有限差分（2-D FDTD）方法，验证了Barbosa提出的时域方法（B-P公式）在距离闪电通道30 ~ 1000 m范围内计算地表雷击辐射水平电场的可行性。结果表明，除闪电通道附近距离（如30 m）外，B-P近似公式可以近似预测50 ~ 1000 m范围内的场峰值，精度在10%以内，且对后续回击的精度与第一次回击的精度基本一致。B-P近似公式预测的场波上升时间部分与二维时域有限差分法预测的场波上升时间部分相似，但B-P近似公式预测的波尾可能比二维时域有限差分法预测的波尾短（如30米和50米）。
Based on the two-dimensional finite-difference time-domain (2-D FDTD) method, we have validated the time-domain method presented by Barbosa (B-P formula) for calculating the lightning-radiated horizontal electric field at the earth surface within distances from 30 to 1000 m from the lightning channel, considering the horizontally stratified earth. The results show that, except for distances in the vicinity of the lightning channel (e.g., 30 m), the B-P approximate formula can approximately predict the field peak value from 50 to 1000 m with a satisfactory accuracy within errors of 10% and its accuracy for subsequent return strokes seems to be more or less the same as that for first return strokes. The rise-time part of the field wave predicted by the B-P approximate formula is similar to that predicted by the 2-D FDTD, however, the tail of the wave predicted by the B-P approximation may be shorter than that by the 2-D FDTD (e.g., 30 and 50 m).
