Arctic Oscillation Modulates climate over Northeast Iran

Global warming and consequently extreme climate has blurred future climate of Iranian plateau IP). Pastclimate and historical records over east Iran are not compelling enough for exceeding understanding oflong-term climate anomalies over IP and in particular in NE Iran in the vicinity of Iran central and Karakumdeserts . Our ۱۴۰۰ year long lake sediment multiproxy record of Green Spring lake (GSL) display therelatively dry and stable climate of medieval climate anomaly (۹۰۰-۱۲۲۰) and anomalous climate during LIA(۱۲۲۰-۱۸۲۰). GSL record is not only a promising narrator of timing of Siberian High (SH) strengtheningwhich have argued to be a contributing factor to Mongol conquest of Persia (۱۲۱۹-۱۲۲۱) but also recordedlong-term forcing of Arctic oscillation (AO) and Eurasia snow cover extent (SCE). GSL record emphasizingthe importance of global warming and consequent extreme climate over NE Iran and region to portrayimproved vision of future hydroclimatic changes in drought-prone of eastern Iran.
