This article devoted to the study of gas heating in the region of an electric interelectrode discharge. The dynamics of local heating is studied using numerical methods and experimentally using an interferometer. The research results make it possible to evaluate the change in the temperature distribution in the cross section of the discharge track, the dynamics of the maximum heating temperature and the size of the heated area.

Streamers are non-thermal filamentary plasmas developing in insulating mediums under the influence of strong external electric field. The subcritical streamer discharge is formed by a field with the intensity smaller than the minimum intensity leading to the air breakdown, and breakdown conditions are created by special initiators. Air breakdown in sub-and supersonic flows induced by the subcritical streamer discharge and the effect of the initiator shape on breakdown conditions are studied. The intensity of electric field of subcritical streamer induced breakdown has been shown to be smaller compared to that initiated by microwave discharge without initiator. The dependencies of critical intensity of the electric field on the pressure and location of initiator are reported. The air breakdown conditions are found at various dimensions of the metallic screen near which the initiator is installed.

Results of experiments on a propagation of a pressure wave with a shock-wave leading front through a gas region excited by a pulsed freely localized discharge of the microwave wavelength range are described. The discharge was realized in air at a pressure from 14 to 100 Torr in the focal region of a quasi-optical electromagnetic beam of the microwave wavelength range. The experiments revealed three types of interaction of the gas-dynamic pulse with the region excited by the discharge in the post-discharge mode. The specific type of interaction is defined by the initial structure of the discharge and the delay time of the gas-dynamic pulse passage through the excited region.
