Documentation of mid-latitude hydroclimate responses to late Pleistocene North Atlanticclimate change is sparse and fragmented due to a lack of continuous and well dated
reconstructions. Here we analyze the remote effects of Heinrich events to understand the
relationship between periods of North Atlantic climate changes and Central Asia’s
precipitation variability. We analyzed trace element, δ18O and δ13C data as proxies for
precipitation variability. Comparison of these proxies with climate records of northern
hemisphere high and low latitude climate changes reveals several episodes of
increased precipitation over Central Asia that coincide with cooling of the northern high
latitude and weakening of northern hemisphere monsoon. We propose two atmospheric links
between the North Atlantic and Central Asia which likely brought increased moisture to the
region during Heinrich events 4 and 5: the Westerly Jet and Siberian High.
