摘    要:Recent tree-ring studies in Mongolia provide evidence of unusual warming that is in agreement with large-scal reconstructed and recorded temperaturec for the Northern Hemisphere and the Arctic.One Mongolian proxy record for temperature extends back over 1000 years and several others are over 350 years in length.Precipitation reconstructions based on thee rings reflect recent increases but also indicate that the increases are within the long-term range of varlations.Spectral analyses of recorded preciplta-tion data and the reconstructions support the hypotheses of quasi-solar periodicity in precipitation variation,previously suggested by others.

Abstract:Recent tree-ring studies in Mongolia provide evidence of unusual warming that is in agreement with large-scale reconstructed and recorded temperatures for the Northern Hemisphere and the Arctic. One Mongolian proxy record for temperature extends back over 1000 years and several others are over 350 years in length. Precipitation reconstructions based on tree rings reflect recent increases but also indicate that the increases are within the long-term range of variations. Spectral analyses of recorded precipitation data and the reconstructions support the hypotheses of quasi-solar periodicity in precipitation variation, previously suggested by others.
Keywords:tree rings  Mongolia  paleoclimate  climatic change
