Abstract

Isotope ratios of rainfall and water vapor during the passage of Typhoon Shanshan were observed in Ishigaki Island, southwestern part of Japan, on 15-16 September 2006. Observational results show that the isotope ratios of rainfall in rainband accompanying Shanshan decrease radially inward, but appear to be anomalously high in the eye wall. We speculate that the inward decrease in the isotope ratios of rainfall is due to the recycling process, diffusive isotope exchange between rainfall and converging vapor in the boundary layer. On the other hand, the anomalously high isotope ratios of the eye-wall rainfall is a consequence of their local cycling process which is a major source of the precipitating vapor for the typhoon inner region.
