Abstract
The results of the study of aircraft icing occurrence are presented, depending on the season and altitude, for Tomsk International Airport in the period from 2011 to 2015. It is shown that in the vicinity of the Tomsk International Airport in autumn the maximum icing occurrence is 43% of all cases. In winter and spring, the icing occurrence has an equal probability of 26%, and in summer, an aircraft can be exposed to icing only in 5% of all cases. It was found that, on average over the period, 89.6% of the icing events were recorded at altitudes from the ground level to 2999 m, and above 6000 m icing has not been reported. In winter, the maximum number of icing events was recorded at altitudes from 0 to 999 m. In autumn and spring, the maximum number of icing events was accounted in the layer from 1000 to 1999 m. In summer, the maximum of icing occurrence is in the altitude layer from 1000 to 1999 m, but it is not pronounced. Altitude dependencies of icing occurrence for the Tomsk airport is different from the results previously published for the continental United States and European territory of the USSR.
