Lake sediment‐based estimates of sediment yield have frequently been used to reconstruct changing patterns of sediment supply arising from environmental change. Such analyses have often emphasized the importance of anthropogenic factors and, in particular, changing land use of management practices over timescales beyond the scope of direct process monitoring. This paper examines several U.K. sediment yield chronologies within the context of mesoscale atmospheric circulation patterns. Changes in the frequency of the winter cyclonic Lamb weather type since 1861 were found to account for a significant proportion of the variation in sediment yields. The results also have implications for future sediment accumulation rates given the potential geomorphological consequences of global climate change. © 1997 by John Wiley & Sons, Ltd.
