Analysis of the meteorological situation in the conditions of icing and ice

Abstract

The article is devoted to the study of the problem of ensuring the safety of aircraft on the territory of the Republic of Belarus and, directly, on the territory of the Minsk airfield. Icing and ice are some of the most dangerous meteorological phenomena for aviation. In order to prevent accidents related to these phenomena, it is necessary to have a clear idea of the laws of their occurrence and distribution, as well as their relationship to each other. To study the spatial and temporal patterns of ice distribution, the actual meteorological data of Belhydromet for 1989–2016 were processed at all meteorological stations of the Republic of Belarus. Also, charts of the chronological progress of the average monthly number of days with ice and the average annual number of days with ice at all meteorological stations on the territory of the Republic of Belarus for the above period were constructed and analyzed. The tendency to change the average annual number of days with ice over the period from 1989 to 2016 is analysed. The icing analysis for 2014–2018 was also carried out according to the data of the Civil Aviation Meteorological Station «Minsk». The accompanying meteorological elements, such as the shape of the clouds, the direction and strength of the wind, air temperature, as well as the synoptic situation, are analysed. The map of the spatio-temporal distribution of ice is constructed using ArcGIS by the method of equal intervals.
