   Dear Dr. Jones:
   Would you be willing and available to review "Snow anomaly events from historical documents
   during the past two millennia and implication for low-frequency variability of AO/NAO and
   PDO" by Guoqiangchu Chu, Qing Sun, Xiaohua Wang, and Junying Sun, submitted for possible
   publication in the Geophysical Research Letters.
   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
