摘要

As the summit of the Antarctic Plateau, Dome A has been received international attentions.In this paper, observational data of an automatic weather station (AWS) at Dome A in 2005?2007 were used to analyze the seasonal variations of air temperatures near the ground and snow temperatures within a depth of 10 m. Analyses on the air temperatures show a typical feature of the coreless winter, and strong inversion maintains during the long winter. Accordingly the stratification near the ground is dominated by th...
