Experimental observations of strengthening the neutron flux during negative lightning discharges of thunderclouds with tripolar configuration

We consider neutron bursts (Yakutsk cosmic ray spectrograph,105m above sea level) and the electric field during lightning discharges. It was found that the neutron bursts are observed in the negative lightning discharg only. We discuss the possibility of generation of neutrons in the lower part (the...

Summary:We consider neutron bursts (Yakutsk cosmic ray spectrograph,105m above sea level) and the electric field during lightning discharges. It was found that the neutron bursts are observed in the negative lightning discharg only. We discuss the possibility of generation of neutrons in the lower part (the point of impact into the ground) lightning discharge. ► Neutron bursts and the electric field of lightning discharges are considered. ► Neutron bursts have been observed during the negative lightning discharges. ► Generation of neutrons in the near-ground part of lightning is discussed.
