Fig. 4: Temperature and precipitation changes related to AMOC changes.

From: In-phase millennial-scale glacier changes in the tropics and North Atlantic regions during the Holocene

Fig. 4

a Ensemble mean surface temperature change (annual mean value in °C) of five models, showing the difference between hosing and control simulations (blue color shows colder temperatures compared to the control simulation and green color higher precipitations). The stippling indicates where all the model simulations exhibit the same sign of changes. This pattern of temperature change is mainly related to reduced AMOC strength. b Same as (a) but for precipitation (mm/d). c, d 30–90°N AMOC adjusted Holocene temperature changes (blue curves) based on the semi-empirical linear model for TraCE simulation and LOVECLIM simulation (black curves) respectively as compared with temperature reconstruction from ref. 45 (red curve). The standard deviation used is 1.2 Sv for the AMOC. e same as (c, d) but for precipitation in the Charquini region (tropical Andes of Bolivia 16°S, 68°W). A 100-year running mean has been applied to the time series in (c–e).
