Short Summary

This study investigates the response and variability of the Atlantic Meridional Overturning Circulation (AMOC) strength to orbital precessional forcing using a suite of Earth System Model simulations. The associated dataset provides model output to diagnose AMOC strength and its variability across different precessional phases.

Objective

• To isolate and diagnose the response of the Atlantic Meridional Overturning Circulation (AMOC) strength and its variability to orbital precessional forcing.

Study Configuration

• Spatial Scale: Global ocean, with a specific focus on the Atlantic basin.
• Temporal Scale: Paleoclimate timescales, investigating the impact of orbital precessional cycles (on the order of 10^4 years) through 24 time-slice simulations.

Methodology and Data

• Models used: AWI-ESM (Alfred Wegener Institute Earth System Model)
• Data sources: Model output from a suite of 24 time-slice simulations, specifically the Atlantic meridional overturning stream function.

Main Results

The provided text is a description of the dataset used in the study and does not contain the specific key findings or quantitative results of the associated manuscript. The dataset is designed to allow diagnosis of AMOC strength and its variability across different precessional phases.

Contributions

• Provides a controlled experimental design using time-slice simulations to isolate the AMOC response solely to orbital precessional forcing, keeping all other boundary conditions fixed.
• Offers a dataset for reproducing and further analyzing the sensitivity of large-scale Atlantic overturning circulation to orbital forcing.
