摘要：

The wide band (0.1-30 MHz) high time resolution (16 ns) radio interferometer is constructed and used to study the initial radio emission of lightning. It is established that the first lightning radio pulse is bipolar and its form, width and amplitude agree with theoretical predictions [Phys. Lett. A 301 (2002) 320]. From observations follows: (a) The runaway breakdown (RB) conditions are fulfilled in thundercloud during noticeable part of storm time; (b) The lightning is initiated by a combined action of RB and extensive atmospheric shower generated by cosmic ray particle having the energy epsilon similar to 10(16) eV. The RB effect in thunderclouds plays a role of lightning "spark chamber" and can be used for radio detection of high energy cosmic ray particles. (C) 2003 Published by Elsevier Science B.V.
