使用第21次中国南极科学考察(CHINARE 21,2004/05)期间获取的东南极中山站-DomeA(昆仑站)长为1183km的冰盖断面车载冰雷达数据。首次揭示了该断面的冰盖内部环境要素-内部等时层结构,显示出沉积不同深度上的古冰盖表面的几何特征。对整个断面冰盖内部的连续层、断裂层和信号空白区(Echo Free Zone)进行了识别及分类,给出其空间分布。找出从雷达断面上Lambert裂谷的表面高程、快速冰流区。讨论了内部等时层形态及其分布与冰盖动力学性质的关系。

1999/2000年中国第15次南极科学考察队在东南极DT401点钻取了一支长102.65m的冰芯,通过对其中包含的近1000年来积累率记录的分析得知,在"小冰期"事件持续时段内DT401冰芯积累率显著低于"中世纪暖期".各种化学离子在该时段内的分布均指示"小冰期"事件在DT401地区可能是存在的.其中Na+、Mg2+海盐源离子的浓度在"小冰期"时段的浓度和波动幅度均高于"中世纪暖期",可能与寒冷
对比分析2005~2008年五种再分析资料和东南极地区气象站实测的日平均2m气温,结果表明:五种再分析资料都能够解释超过70%的方差,年均方根误差为3.4℃~6.9℃.三种NOAA再分析资料NCEP-1、NCEP-2和20CRv2呈现冷偏差(分别为2.5℃,1.4℃和1.5℃),ERA Interim和JCDAS呈现暖偏差(分别为1.7℃和2.0℃).五种再分析气温通常在(南半球)春季适用性强,冬
利用第27次和28次中国南极内陆考察队在东南极冰盖最高点昆仑站获取的2011和2012年夏季GPS探空资料,对南极高原大气边界层动力特征进行了分析.结果表明,南极冰盖大气边界层中存在多层逆温结构,强逆温层出现在500m以下高度,边界层平均高度为890m,并存在上午低,午间高的日变化特征.风随高度的分布与理论计算的Ekman螺旋曲线既有相似,也存在差异.风速随高度增加快速、风向左转,存在显著的Ekm
