Interannual variation in stable isotopes in water vapor over the Northern Tibetan Plateau Linked to ENSO
The contrasting responses of ice core δ18O records (δ18Oice) from the northern and southern Tibetan Plateau (TP) to the El Niño Southern Oscillation (ENSO) complicate δ18Oice-based temperature reconstructions. These contrasting responses were explored using stable hydrogen isotopes in water vapor (δ...
