Аннотация:Abstract—Based on instrumental observation data from meteporological stations located in the SouthernUrals, an integrated index of the fire hazard and an index of forest fire hazard have been calculated for thewarm season (May‒September) from 1978 to 2020. The analysis was based on the daily values of surface airtemperature, amount of precipitation, dew point deficit, average wind speed, moisture index, and number ofdays after the last rain. A correlation analysis between the critical values of the fire hazard indices and actualdata on forest fires has been carried out; as a result, a close relationship has been revealed between the extremevalues of the fire hazard indices and abnormally hot years. A general trend towards changes has been recordedfor most of the meteorological stations with respect to the maximum values of the fire hazard indices. Thefire hazard indices are compared with the results of space monitoring of wildfires from the Terra-MODIS sat-ellite. An increase in the number of cases of dangerous meteorological conditions from 1995 to 2000 and adecrease in the number of days with the critical values of fire hazard indices from 2000 to 2005 have beenrevealed. Fire hazard indices differently reflect the set of meteorological conditions contributing to the occur-rence of fires. Thus, unlike the integrated index of fire hazard, the index of forest fire hazard takes intoaccount not only meteorological, but also environmental factors. The resulting values of the fire hazard indi-ces have been structured in the form of a database that can be used in meteorological forecasts to assess andpredict fire conditions based on weather conditions.
