Compared with the glacial and Younger Dryas, ISM precipitation was enhanced during the Bølling-Ållerød. ISM precipitation was apparently coupled to variations in the East Asian monsoon and North Atlantic climate on millennial and multicentennial time scales during the deglaciation. Analyses of a high growth rate interval (<2.5 yr resolution) encompassing the late Bølling–early Ållerød suggest that multidecadal monsoon variability was an important aspect of ISM behavior at that time. The frequency spectrum of ISM precipitation during this time interval is similar to that of the Δ14C record and other ISM precipitation records during the latest Holocene. This raises the hypothesis that multidecadal climate dynamics during the late Bølling–early Ållerød may have been similar to those that operated during the last several millennia, even though the boundary conditions of these two time intervals were very different.
