Climate Water Balance in the Warm Half-Year and Its Circulation Conditions in the Sudetes Mountains and Their Foreland (Poland and Czechia)

Bartlomiej Miszuk    

Resumen

Mountains are one of the most sensitive regions in terms of climate changes. This also concerns water balance, which plays an important role, especially in the context of the ecological state. Furthermore, numerous studies indicate the atmospheric circulation as one of the crucial factors affecting climate conditions. Therefore, the goal of the paper is to examine the impact of the atmospheric circulation on the changes in climate water balance (CWB) in the Sudetes Mountains and their foreland. The analysis was carried out based on the 1981?2020 data derived from the Polish and Czech meteorological stations. The impact of the circulation factor was examined using the Litynski classification, while the calculation of evapotranspiration based on the Penman?Monteith equation. The results showed that despite positive trends for evapotranspiration, the changes in CWB in 1981?2020 were generally statistically insignificant. The only exception was the increase in CWB under the eastern circulation and its negative tendency for the western and southern sectors for some of the stations. This corresponds to the changes in the frequency of the circulation types. The results of the study can be used in further research on water balance in the region.
