Such factor of occurrence of forest fires, as the focused sunlight is considered in present paper. Selected periods of fire-dangerous season of 2013 year in territory of the Timiryazevskiy local forest area of the Timiryazevskiy forest area of Tomsk region are investigated. The concave-convex glass lens is usedas the solar energy concentrator. Physical modelling is spent on specially made experimental installation. Ignition delay times of forest fuel layer are defined at influence of the focused sunlight. Influence of such meteorological parameter as speed of a wind in a ground layer of atmosphere is considered at scenario estimation. Data on control ignitions of 2013 year and archives of meteorological parameters on observedforestry territories are used. Preliminary conclusions are drawn on influence of some meteorological conditions on level of forest fire danger.
