英文摘要 | The climate's response to forcing depends on how efficiently heat is absorbed by the ocean. Much, if not most, of this ocean heat uptake results from the passive transport of warm surface waters into the ocean's interior. Here we examine how geographic patterns of surface warming influence the efficiency of this passive heat uptake process. We show that the average pattern of surface warming in CMIP5 damps passive ocean heat uptake efficiency by nearly 25%, as compared to homogeneous surface warming. This ``pattern effect" occurs because strong ventilation and weak surface warming are robustly co‐located, particularly in the Southern Ocean. However, variations in warming patterns across CMIP5 do not drive significant ensemble‐spread in passive ocean heat uptake efficiency. This spread is likely linked to inter‐model differences in ocean circulation, which our idealized results suggest may be dominated by differences in Southern Ocean and subtropical ventilation processes. |
