“…This mechanism is also verified by numerical results (CTRL and 0.1 A experiments), which have been analyzed in summer, autumn and winter in previous studies (H. Dai, 2021;Dai & Yao, 2023;Dai et al, 2021Dai et al, , 2022. Climate anomalies in the Arctic region of the sensitivity experiment are comparable with those in the observation, although they are much larger in magnitude.…”

“…Nevertheless, meridional heat transport cannot increase this much, because the atmospheric circulation or temperature cannot increase by 10 times that in recent years. Instead, the AHT decreases because Hadley cell shrinks at lower latitudes (Dai & Yao, 2023). In this case, the surface energy budget anomaly over the Antarctic results from local forcing and feedback.…”

“…Most surface energy budget anomalies over the Antarctic, which are stored in the Southern Ocean, are considered to be the reason for recent Southern Ocean warming. However, a recent timescale analysis (Dai & Yao, 2023) suggested that the timescale of ocean temperature spin up in idealized numerical experiments (0.1A) is mainly determined by variations in northward meridional ocean heat transport, which is controlled by the strength of the Atlantic meridional overturning circulation. It would be interesting to find out how local surface forcing and ocean circulation adjustment compete or collaborate to reach equilibrium in the ocean temperature field in a future study.…”
