Short summary
Seismic profiles from the western and eastern deltas of Lake Issyk-Kul were used to identify lake-level changes of up to 400 m. Seven stratigraphic sequences were identified, each containing a series of delta lobes that were formed during former lake-level stillstands. Lake-level fluctuations point to significant changes in the strength and position of the Siberian High and the mid-latitude Westerlies. Their interplay is responsible for the amount of moisture that reaches this area.
