英文摘要In the summer of 2005, one negative lightning flash was artificially triggered in Shandong Province (117 degrees 48' E, 37 degrees 42'N), middle latitude region of eastern China. The flash included 10 return strokes, and the geometric mean value of the current peak was 11.9 kA (the average value was 12.6 kA) with a maximum of 21.0 kA and a minimum of 6.6 kA, similar to the subsequent return strokes in natural lightning. The geometric mean value of half peak width was 39 mu s (the average value was 40 mu s), which was much larger than the usual result. Based on the Diendorfer and Uman (DU) model, the return-stroke current waveforms and charge distribution along the lightning channel are discussed. The simulated current waveforms, being divided into breakdown and corona current components, are in agreement with the optical measurements when the two different discharge time constants are properly chosen.
