ARTICLE ANNOTATION

quote
The article studies statistical correlations between meteorological and hydrological drought on the example of the Pskem and Ugam rivers. In this research standard hydrometeorological data on precipitation observed at the Pskem meteorological station and mean monthly water discharges measured on the Pskem and Ugam rivers were used. The meteorological drought indices (SPI) and hydrological drought indices (SSI) were calculated using SPI generator computer program. Statistical relations between SPI and SSI indices for the selected rivers were estimated on Pearson correlation coefficient. The "hit-score" values, that allow predicting hydrological drought for selected period based on meteorological drought, were determined, The results showed that there is a possibility of using the hit-score method for predicting hydrological drought.
