Composite sea-surface temperature anomalies for high and low local dimension. Composite sea-surface temperature anomalies (units: K) with respect to the climatological seasonal cycles for days with dSST above (a, c, e) and below (b, d, f) the respective median values. Datasets: COBE, as used in 20CRv2c (a, b), ERA20CM (c, d) and CERA20C (e, f)
