Monsoons in Space and Time: Patterns, Mechanisms and Impacts
Convenors
Rengaswamy Ramesh, Rajeev Saraswat, Ralph Schneider, Pinxian Wang
Description
Monsoon is the life-line of several low-latitude regions. Any change in monsoon precipitation severely affects the food production for the population-rich societies. In order to be able to predict imminent monsoon changes, it is important to understand the dynamics of the monsoon system at regional and global scales. Studies of past monsoon variability over long time periods from different proxy records as well as synoptic results from sensitivity experiments with Earth system models, will help to understand monsoon dynamics.
Such records and model results are also required to distinguish between natural and anthropogenic contributions in monsoon variability. Therefore, the proposed session will include contributions that discuss past monsoon changes from both the terrestrial and marine archives as well as from paleoclimate modelling.
