Current changes of precipitation in warm season and streamflow formation during low-flow period over territory of Belarus
Abstract
The study presents an assessment of the moistening regime over territory of Belarus in warm season and as resulting parameter – surface streamflow during low-flow season. The tendencies of monthly precipitation, maximal daily totals and duration of rainfall were detected; streamflow characteristics, such as the lowest discharges for the low-flow season and highest discharges of rain floods were estimated. The Standard Precipitation Index and Standard Streamflow Index were calculated to estimate the drying conditions over territory of Belarus. Despite the insignificant change of the annual precipitation during the period of 1989–2018, the intensification of rain falling has increased over territory of Belarus but at the same time the number of meteorological droughts growth in May-September. The streamflow rate didn’t change significant but the highest rain floods discharges and/or the lowest discharges during low-flow season has growth (except the Neman River basin) while hydrological droughts repeatability also has increased in all river basins of the study region.
