Equilibrium simulations of Marine Isotope Stage 3 climate

Abstract: Abstract. An equilibrium simulation of Marine Isotope Stage 3 (MIS3) climate with boundary conditions characteristic of Greenland Interstadial 8 (GI-8; 38 kyr BP) is carried out with the Norwegian Earth System Model (NorESM). A computationally efficient configuration of the model enables long integrations at relatively high resolution, with the simulations reaching a quasi-equilibrium state after 2500 years. We assess the characteristics of the simulated large-scale atmosphere and ocean circulation, precipitat… Show more

“…The strengths of these global surface cooling are smaller compared with that obtained from the LGM simulation (5.2 °C) with the same model. The simulated MIS3 cooling falls within the range of simulations obtained from 170 previous modelling studies: Guo et al (2019) simulate the MIS3 climate with the boundary conditions of 38 ka and show a global cooling of 2.9 °C, Merkel et al (2010) show a cooling of 3.4 °C under 35-ka boundary conditions, Zhang et al (2014b) show a cooling of 3.5 °C under 38-ka boundary conditions, and Brandefelt et al (2011) show a global cooling of 5.5 °C under 44-ka boundary conditions. The spatial maps of the surface cooling show a well-known polar amplification pattern (Fig.…”

“…Recently, the amount of reconstruction of mid-glacial 420 period is increasing (Jensen et al 2018), and hence more detailed comparisons with these reconstructions need to be conducted in future. Furthermore, the present results provide a reference climate state for investigating the millennial time-scale climate variability that occurred during the mid and early glacial period (Henry et al 2016, Mitsui and Crucifix 2017, Guo et al 2019. In a forthcoming study, we will perform freshwater hosing experiments with these…”

“…This AMOC sensitivity to CO 2 changes seems to occur in models that display deep-water formation in the northern North Atlantic, south of Iceland. By contrast, models that simulate deep-water formation in the Nordic Seas display a much higher AMOC stability to changes in CO 2 under MIS 3 boundary conditions 176 , potentially indicating that AMOC stability is dependent on the location and strength of deep-water formation.…”
