自然界中一次球状闪电的产生过程分析

Analysis on the Generation of a Nature ball Lightning

球状闪电是自然界中非常罕见的一种物理现象.由于球状闪电的发生具有不可预知性、频率低、时间短等特点,对它进行科学研究存在很大的困难.本文依据无狭缝光谱仪拍摄到的一次高原地区发生的球状闪电资料,对自然界中球状闪电的产生过程进行了研究.利用光谱讨论了球状闪电发生过程中温度的变化,同时也分析了球状闪电产生位置周围的地貌、土壤、环境等条件.

Ball lightning is a rare physical phenomenon in nature. It is very difficult to conduct the scientif- ic research due to the occurrence of ball lightning have the peculiarity of unpredictability, low frequency and short time. According to the data of ball lightning shot by slitless spectrograph in plateau, the generation process of nature ball lightning has been studied. The temperature of ball lightning in the generation process is discussed and the landform, soil and environment around the location of ball lightning are also analyzed.
