Physicists found out why the lightning hits into one place twice

The international group of physicists used the LOFAR telescope (Low-Frequency Array) to examination why the lightning can strike twice to the same place.

Thanks to the modern equipment, scientists received pictures of electric discharges with nanosecond expansion.

"These data allowed us to study lightnings so in detail that we could reach primary processes which are the cornerstone of this phenomenon", - quotes the edition of the physicist Bryan to Chara from the Groningen university.

the Lightning arises at first from emergence of a plasma pocket - the small sphere consisting from the ionized and warmed gas. From it charges disperse, forming a peculiar network of channels.

of LOFAR showed to physics that these channels carry out not all category. Some of particles get through gaps in channels of the category and provoke emergence of so-called needles.

These needles exist very short period. They remained out of sight of other scientists who investigated lightnings.

Through these structures also occurs an above-mentioned phenomenon - double electric shock to the same place. Above-mentioned needles perform function of guides for new categories.
