LGM thermocline depth anomaly in the eastern Indian Ocean vs. equatorial Indian Ocean zonal wind anomaly as simulated in PMIP2 and PMIP3/CMIP5 models. ΔT is used as a measure for thermocline depth and defined as the annual mean temperature difference between surface and 70 m averaged over the eastern Indian Ocean region 4° N–6° S, 94° E–104° E. U eq is defined as the annual mean zonal low-level (925 hPa) wind averaged over 5° N–5° S, 50° E–100° E (Fig. 5). Shown are LGM anomalies relative to pre-industrial control runs for both quantities. The models are numbered as in Supplementary Table 2. Models with strongest LGM thermocline deepening and westerly wind anomalies are CCSM3 (No. 13) and FGOALS-g1.0 (No. 14)
