Short summary
As the Arctic warms, changes in sea ice and sea surface temperature are altering global climate patterns. Our study links Barents–Kara Sea (BKS) ice loss and rising sea surface temperatures to increased summer rainfall in the Yangtze River basin. The thermal forcing from the BKS triggers a Rossby wave train that enhances moisture transport and anomalous ascending motions, leading to increased rainfall. Understanding this connection is crucial for predicting summer rainfall in East Asia.
