The manuscript's abstract is: We present historical snow anomaly events during the past two millennia which provide a unique temporal window to studying long-term AO/NAO, a prominent phenomenon in wintertime. The variations of positive/negative snow abnormal events show clear decadal to century variations during the past two millennia. Based on the previous instrumental research and comparison with other reconstruction data, we suggest the Index of Abnormal Snow (IAS) may be an AO-like atmospheric variability. The winter during the Medieval Warm Period (MWP) might be strongly influenced by a predominantly positive AO with less snow condition, whereas the Little Ice Age (LIA) by negative AO concomitant with heavier snowfalls in East Asia. Low-frequency variability of snow records may be intrinsic to the natural climate system. Moreover, the data provide a case for numerical models, because the MWP may be more closely comparable to modern conditions If you agree to review this manuscript, I would ask for your comments within 14 days from your acceptance.
