Abstract

The modelling dataset presented here corresponds to the manuscript entitled "Australasian hydroclimate response to the collapse of the Atlantic Meridional Overturning Circulation under pre-industrial and Last Interglacial climates".  

Over the last 50 years, the AMOC has weakened and is projected to weaken further or even collapse this century due to freshwater influx from melting glaciers and ice sheets, under climate warming driven by rising greenhouse gas concentrations. Despite numerous modelling studies investigating the climatic impacts of an AMOC shutdown, little is known about its impact on Australasian hydroclimate, particularly under climatic conditions warmer than the pre-industrial (PI). Here, using the ACCESS-ESM1.5 model, we assess the processes impacting seasonal hydroclimate in the Australasian region in response to an AMOC shutdown under PI and Last Interglacial (LIG) climatic background conditions.
