The mid-Holocene is one of the key times in the past to test models. The most prominent difference between the mid-Holocene and the present arises from the orbital configuration, which leads to an increase in summer insolation in the northern hemisphere and a decrease in the tropical and subtropical southern hemisphere in boreal winter (Lohmann et al., 2013). Several model simulations were performed to test whether the resolution of the model systems used affects the results. Special focus is put on the boreal winter atmospheric circulation in the northern hemisphere (Lohmann et al., 2021).
