Global Monsoons: Improving Predictions for Future Sustainability
Session ID#: 81360
Session Description:
Monsoon is a unique feature of Earth’s climate, associated with an annual reversal of surface winds determining the economy and well-being of a significant global population. Seven major monsoonal-systems operate through Eurasia-to-Australia, Africa and America, relating to heat transport across regions. This session will focus on improving predictability of the Global monsoon, with particular focus on Global sustainability. This emerging Global monsoon concept in climatology manifests as coupled atmosphere-land-ocean-cryosphere-biosphere interactions, and while the ultimate driver for monsoons is solar forcing, several local factors provide significant feedbacks. The challenge is to understand these complexities and enhance predictability. The paradigm of “thinking Global and looking local” deserves significant attention for improving predictability on a local scale. The present session will aim to understand how paleorecords can allow improvement in forecast through downscaling. It will also discuss the type and nature of paleo-records necessary to improve prediction of seasonality, quasi-periodicity, irregularity, and instability.
