ABSTRACT Global warming has increased the risk of meteorological drought and associated hazards. Based on daily data from 35 stations in Songhua River Basin (SRB) collected 1960 to 2019, this study applied standardised precipitation evapotranspiration index (SPEI) used ensemble empirical mode decomposition (EEMD) method Pettitt's mutation test perform a partitioned segmentation analysis multi-temporal spatial variations droughts affecting basin terms frequency intensity, discussed relationship between atmospheric circulation drought. The results showed that overall trends shifted humid trend 2019. had periods 3, 6.7, 15, 30 years, with points 1968, 1980, 1997, 2012. Regions I IV entire was enhanced, while II, III, V weakened. Drought strongly influenced by Arctic Oscillation (AO) Southern Index (SOI).
