Spatial and temporal distribution of very strong wind frequency of occurrence in the cold period of the year in the territory of Belarus
Abstract
The study analyzes very strong (including squally) winds during the cold season in the territory of Belarus. The main meteorological conditions for the development of a hazardous hydrometeorological phenomenon from November to March have been determined based on the processing of data from the network of hydrometeorological observations of Belarus for the period 1989-2022, when the country has a steady increase in air temperature, especially during the cold season. Maps of the spatial distribution of cases of very strong wind have been constructed. The recurrence and development trends of a hazardous hydrometeorological phenomenon in a changing climate are presented. The results of the conducted studies have shown that very strong gusty winds are most often recorded in the northwestern and eastern regions of the country, and there has also been an increase in the number of hazardous hydrometeorological phenomena in the last decade. In addition to the physical and geographical conditions of weather stations that affect the spatial and temporal distribution of the phenomenon under study, surface synoptic, high-altitude aerological factors contributing to the strengthening of the wind to the criteria of very strong are determined. The revealed patterns of spatial and temporal distribution can be used to develop environmental protection measures in order to reduce the negative consequences of hazardous weather phenomena, and the established links between the considered hazardous hydrometeorological phenomenon and the aerosynoptic conditions of its formation can be used to replenish the methodological base on forecasting very strong (including squally) winds in the cold season.
