Extended Data Fig. 2: The restoration region and buffer zones for pacemaker experiments.
From: Walker circulation strengthening driven by sea surface temperature changes outside the tropics
The restoration region (pink) and buffer zones (sky-blue) for each pacemaker experiment as indicated: XTOGA15 (a); XTOGA25 (b); XPOGA15 (c); XPOGA25 (d); XNPTOGA15 (e); POGA (f); SPOGA (g). Sea surface temperature (SST) in the pink-colored region is restored toward the model climatology plus the observed anomaly. In pacemaker experiments by CM2.1, the observed SST anomaly is calculated based on ERSSTv5 (except POGA which uses ERSST version 3b extended by ERSSTv5), while in XTOGA15 by MIROC6, SST anomaly is based on COBE-SST2. See Methods for the detailed explanation of the restoration region and buffer zones. The red rectangles in 2ab represent the reference regions of Fig. 4a.
