Short summary
Water vapor source and transport are linked to the stable isotopes of precipitation of 70 storms at Barrow, AK, USA. Barrow's vapor came from the North Pacific in winter and the Arctic Ocean in summer. Half the isotopic variability was explained by the size of the temperature drop from the vapor source to Barrow, the evaporation conditions, and whether the vapor traveled over mountains. Because isotopes reflect the regional meteorology they may be early indicators of Arctic hydroclimatic change.
