The possibility of modeling of altitude-triggered lightning (ATL) under laboratory conditions using charge initiation by a crossbow bolt, in the electric field of an artificial cloud of a negatively charged water aerosol, has been demonstrated for the first time. Over one hundred of such events have been registered. For each event, a high-speed camcorder recorded the dynamics of the upward positive leaders with streamer corona, followed by a return stroke and channel plasma decay. Integrated photos of the events have also been obtained. Simultaneously, we measured the current flowing through the bolt in the plasma channel. A similarity of the discharge initiated by the bolt in the electric field of an artificial cloud of charged aerosol to the altitude-triggered lightning in nature is discussed.
