The paper uses the series of meteorological data from the VEGA-Science satellite information service. For information on fires, we used the Federal Forestry Agency data for the Republic of Buryatia, which are numerical time series of annual indicators for the number and area of fires in the republic forestries from 2001 to 2018. A correlation analysis was carried out in two climatically contrasting landscapes of the Eastern Baikal region and the Selenga Middle Mountains to assess the quantitative relationship of meteorological parameters with the number and area of fires. Contrasting indicators of atmospheric climate are humid Baikal forestry and arid Ivolginsky forestry. Humid is a climate in which atmospheric precipitation prevails over evaporation; in an arid (dry) climate, the evaporation amount significantly exceeds atmospheric precipitation. Humid Baikal forestry is located on the shores of Lake Baikal (Eastern Baikal), Ivolginsky forestry is located in the central part of the Selenga Middle Mountains and is typical of arid ecosystems. A noticeable correlation was found between wildfire and soil moisture.
Keywords: meteorological data of satellite information service VEGA-Science, forest fires, correlation analysis, humid climate, arid climate
