IK, OS, RL, and LU are supported by the international cooperation program of the ASCR grant M10042120 and by the GACR project 205-09-1253. JB is supported by the Earth-system project TAMOP-4.2.2.C-11/1/KONV-2012-0015 sponsored by the EU and European Social Foundation. OV is supported by the Spanish Ministry of Science and Innovation under project AYA2011-29936-C05-04. ChH acknowledges an ERC starting grant from the European Union. The acceleration of electrons results in observable electromagnetic waves which can be used for remote sensing. Here, we make use of similar to 4 Hz-66 MHz radio waves emitted by two consecutive intense positive lightning discharges to investigate their impact on the atmosphere above a thundercloud. It is found that the first positive lightning discharge initiates a sprite where electrons are accelerated during the exponential growth and branching of the sprite streamers. This preconditioned plasma above the thundercloud is subsequently exposed to a second positive lightning discharge associated with a bouncing-wave discharge. This discharge process causes a re-brightening of the existing sprite streamers above the thundercloud and initiates a subsequent relativistic electron beam. Publisher PDF |
