Frequent invasions of cold air masses in November in combination with a negative radiation balance of the earth's surface create conditions for the formation of a winter weather regime. The air temperature is increasingly becoming negative. The transition of the average daily temperature through 0 ° С towards a decrease is considered the beginning of winter. On average, it begins in the Northern and North-Eastern regions of the Republic in the second decade and ends in the South-West at the end of the third decade, and in Brest this transition is carried out on December 3.
