Abstract: Results of field experiments on researching occurrence and spreading of steppe fires are presented. Values of temperature characteristics in the front of burning and speed of fire front spread depending on wind velocity are presented. Occurrence of a steppe fire from a pointlike source of ignition and probability of its occurrence depending on the size and type of the ignition source are investigated.

Keywords: steppe fire, speed of spread, flame temperature, probability of fire initiation, point source of ignition.
