| Abstract: | Some of results from China-United States glaciological expedition to Guliya Ice Cap region in May, 1991 are shown in this paper, which preliminarily analyzes the variable features of the air temperature and circulation in the snow-ice cover and snow-ice free regions in the Guliya area. The results are as follows: 1) the variable range of the temperature in the snow-ice free region is larger than that in the snow-ice cover region. 2) the biased west windwas prevaling in the snow-ice free region, which is related to the sink of cold air formed under the strong cooling effect in the snow-ice cover region. 3) the air masses from the snow-ice cover region are of low temperature and high humidity, but in reverse in the snow-ice free region. 4) there may be a phenomenon called as glaciological front in the transition zone between the snow-ice cover and snow-ice free regions, which provides the foundations to interpret the temperature difference and the jump of wind direction in both regions, as well as the second extreme precipitation-elevation. |
