Abstract

Using high quality, high resolution grain size/magnetic susceptibility records of the Darai Kalon/Chasmanigar (DK, Tajikistan) and Xifeng (XF, China) loess sequences Jia et al. suggest that moisture variations in Arid Central Asia (ACA) lagged those in monsoonal Asia by 2-5 ka over the last 4 interglacials. These lags were quantified using chronologies that were developed via tuning the loess records to the SPECMAP (and partly NorthGRIP-Greenland) curves, i.e. the authors do not provide independent absolute chronologies for the investigated records. This implies that they effectively disregard potential regional differences in climate response during the tuning procedure
