Monsoons in warm climates: new insights from palaeoclimate reconstructions and simulations

Session ID#: 157368

Session Description:
Warm climates are generally associated with an intensification of the global hydrological cycle compared to current conditions. However, changes in regional land-atmosphere feedbacks and dynamic processes such as inter-hemispheric and land-ocean thermal contrasts contribute to shape a complex and uncertain spatial pattern of the Global Monsoon response to global warming. Past periods such as the Early Eocene, the Mid-Pliocene, the Last Interglacial, and the Mid-Holocene provide the opportunity to explore monsoonal dynamics under warm climate states, using indirect evidences from proxy-based palaeoclimate reconstructions and palaeoclimate model simulations. In this session we aim at gathering together palaeoclimatologists and climate modelers to discuss recent advances in the characterisation and understanding of monsoon dynamics in warm climates. We welcome contributions about new proxy-based results and new methods to reconstruct monsoon rainfall, especially high-resolution proxy data that allow exploring sub-centennial variability of individual monsoonal systems. Contributions about tropical and monsoon dynamics from palaeoclimate simulations, including results from model intercomparisons under initiatives such as PMIP are also welcome. We are especially interested in comparative assessments of simulations and reconstructions that highlight major gaps of knowledge about mean state and spatio-temporal variability of the global monsoon under warm climates.
