摘要: AbstractRecent studies have suggested that significant parts of the observed warming in early and late twentieth century were caused by multidecadal internal variability centered Atlantic Pacific Oceans. Here, a novel approach is used searches for segments unforced preindustrial control simulations from global climate models best match (AMV PMV, respectively). In this way, estimates influence AMV PMV on temperature are consistent both spatially across variables made. Combined impacts surface temperatures up to 0.15°C peak-to-peak time scales. Internal contributed between 1920s 1940s, subsequent cooling period, since then. However, variations rate still remain after removing associated with ...
