Potential Impact of Winter–Spring North Atlantic Tripole SSTAs on the Following Autumn–Winter El Niño–Southern Oscillation: Bridging Role of the Tibetan Plateau
Abstract Sea surface temperature anomalies (SSTAs) over the North Atlantic could stimulate the El Niño–Southern Oscillation (ENSO) events through regulating the tropical and mid‐latitude atmospheric circulations. Whether the Tibetan Plateau (TP) play an important bridging role in the mid‐latitude pa...
