. Felauer, Ces zones ont aussi été prise en compte dans l'étude de An et al. (2008) et les conclusions sont donc similaires, mais d'autres commentaires peuvent tout de même être faits. D'une part, le climat lors de la fin de l'Holocène semblerait dépendre des latitudes. Au nord de notre zone d'étude, le climat reste plus humide de -4,5 ka jusqu'à aujourd'hui avec quelques intervalles arides de moins de 500 ans, Peu d'études paléoclimatiques ont été effectuées dans le désert de Gobi, 2006.

A. , Les différentes frises chronologiques présentées Figure A.2 montrent à quel point les résultats des études paléoclimatiques varient spatialement. L'influence des circulations de masse d'air provenant de l'ouest et du sud (Figure A.1), serait une des causes de ces fluctuations spatiotemporelles, 2008.
