From monsoon to global ocean circulation : constraining past climate dynamics using tracers-enabled Earth System Models
In-person in Burt 193 and also on Zoom
Abstract: The integration between geological records and paleoclimate modeling results offers unique opportunity to investigate the behavior of climate system components in a warmer world. Past climate states are also useful to validate the functioning of climate models under extreme pCO2 forcing. Geological records however only provide indirect indications of climatic variables like temperature, precipitation, or ocean circulation. Any comparison with ocean-atmosphere Earth System Models results therefore rely on converting biogeochemical ‘proxy’ data to simulated variables. In most of the deep time paleoclimate studies this step introduce huge uncertainty and lead to long standing gaps in our understanding of past climate events.A way to bridge the gap between simulation and proxy data is to directly simulate biogeochemical (eg. productivity or dissolved oxygen) or isotopic tracers (eg. δ18O) in the models. In this talk I will explore how tracer-enabled climate models can help leveraging on multi-tracers proxy record that sometimes have conflicting interpretation to understand cause of (deep) past climate evolution. To do so I will focus on my work targeting the Miocene (23-5 million of years ago), which is a warmer than present-day geological interval (+5-8°C), that has been over the past years more and more used as potential analogue for future climate change. I will first discuss the long-term evolution of South Asian Monsoon winds and rainfall ; and how it has affected the dynamic of the surface Indian Ocean. I will then introduce some of my ongoing work that focus on understanding how change in the global ocean overturning circulation during this period affects ocean-atmosphere dynamics and would be fingerprinted in the regional patterns of upper ocean temperature and oxygen composition of seawater.
