| Zusammenfassung |
| The Asian summer monsoon affects the economical prosperity of vast, heavily populated regions (almost two-third of humanity). Asian summer monsoon dynamics at the orbital scale is a subject of considerable debate. Central in this debate is the interpretation of the Asian speleothem d18O record as a valid proxy for summer monsoon intensity.
In this study, we present a transient simulation of the last 150,000 years, performed with a numerical isotope-enabled fully coupled atmosphere-ocean-vegetation model (iLOVECLIM). This enables us to assess the nature of the d18O signal in South Asian speleothems. We discuss the validity of Asian speleothem d18O records as a proxy for summer monsoon intensity and the ultimate forcings of Asian monsoon precipitations at orbital scale. |
