Variability of atmospheric circulation and changes in the wind regime of the territory of Belarus
Abstract
The paper considers the influence of atmospheric circulation forms according to Wangenheim – Girs on the wind regime of the territory of Belarus. Maps of average annual wind speeds for circulation epochs are constructed. For the meridional circulation epoch, the most typical are average annual wind speeds from 3.81 to 4.20 m/s, with the eastern circulation form – from 3.01 to 3.60, with the western form – from 2.41 to 3.20 m/s. The fields of average annual wind speeds for the eastern and western forms of atmospheric circulation are similar. The analysis of the statistical significance of the differences in average annual wind speeds between circulation epochs showed significant differences between all circulation epochs.
As a result of the analysis of the sample average repeatability of wind directions for eight rhumbas between the E + C and E circulation epochs, the maximum differences (70.59 %) are characteristic of the southern wind direction, the share of which significantly increases during the eastern circulation epoch. Between the E + C and W epochs, the differences in the repeatability of wind directions are expressed more clearly: the maximum differences are characteristic of the southeastern (76.47 %) and southern (82.35 %) directions. The differences between the variability of wind directions between the E and W circulation epochs are expressed less clearly.
