The Atlantic Multidecadal Oscillation (AMO) is a natural climate pattern in the North Atlantic Ocean that changes over several decades. While its effects are well known near the Atlantic, we found that it also has a clear seasonal impact on distant land areas like central Eurasia. During the warm phase of the AMO, this region tends to get colder in winter and warmer in spring—even though the yearly average temperature change is small. By separating the influence of large-scale wind patterns from local heating effects, we show that most of this seasonal temperature change comes from shifts in atmospheric circulation linked to the AMO. Climate model experiments further suggest that both sea surface temperatures and sea ice changes in the Arctic are important for shaping these patterns, especially in winter. Our findings highlight that this overlooked seasonal influence of the AMO can add uncertainty to predictions of future climate over central Eurasia.
