For a long time, there is no exact explanation for the formation of spherical lightning. 20 12 June, a scientist from China, Lanzhou City, Gansu Province, photographed a luminous ball during a thunderstorm in Qinghai Province, which was considered as spherical lightning in thunderstorm weather. Its video and spectrum are considered to be the first scientific record of spherical lightning in nature so far. The details of this research have been published in the June 20 14 issue of Physical Review Letters.
