Within the long-term research program on reconstruction of palaeoclimatic characteristics of Central Asia, we carried out a palaeoreconstruction of climate aridity/humidity in the Transbaikalia, based on investigating layered palynological spectra and chemical composition of bottom sediments from Lake Arakhlei. It was found that the humid phases of climate on the time interval 90–2005 used in calculations exhibit a periodicity of 20–45 years, which roughly corresponds to the humidity cycles of Eurasia.
