The TMS5e sequence from the Tumen section,at the southern edge of Tengger Desert in the northwestern China,is synchronous with Marine Isotope Stage 5e(MIS5e).It consists of 16 layers of aeolian dune sands,11 layers of lacustrine loess-like facies,and 5 layers of lacustrine facies.The results of grain-size analysis shows that the palaeo-mobile dune sands,palaeo-fixed to semi-fixed dune sands and loess-like sandy loams are mainly composed of sands,ranging from 70% to 96%;their silt contents ranged from 4% to 20%,and their clay contents ranged from 1% to 5%;the climate under which the aeolian dune sands were deposited is similar to that under which modern mobile dune sands form,which is caused by the dominance of the cold,dry East Asian winter monsoon.In contrast,the lacustrine loess-like facies and lacustrine facies had a lower sand contents than those of the three aeolian dune sands,but have higher silt and clay contents,most of their sand content ranged from 30% to 60%,their silt contents ranged from 35% to 55%,and their clay contents ranged from 6% to 20%.The lacustrine loess-like facies and lacustrine facies formed under the influence of the warm,humid East Asian summer monsoon based on their similarity with modern sediments.The grain-size indicator Mz(mean grain diameter) and the SC/D value in the TMS5e sequence indicate climatic insta-bility at the southern edge of the Tengger Desert during MIS5e,with at least 14 fluctuations between a warm,humid climate and a cold,dry climate,divided into five stages:TMS5e5(139 kyr to 129.3 kyr B.P.),TMS5e4(129.3 kyr to 124 kyr B.P.),TMS5e3(124 kyr to 119.5 kyr B.P.),TMS5e2(119.5 kyr to 116.5 kyr B.P.),and TMS5e1(116.5 kyr to 113.7 kyr B.P.).These correspond roughly to MIS5e5,MIS5e4,MIS5e3,MIS5e2,and MIS5e1,respectively,in the GRIP ice core data. 相似文献

高精度、高分辨率的地球重力场可用于统一全球高程基准及确定大地水准面等,因此全面评估重力场模型精度及其快速导出的各重力量（如高程异常等）具有重要意义。本文利用VS2015+Intel XE 2016平台及OpenMP等并行技术研发一套用于重力场模型评估及相关重力量计算的软件--EGMTools,该软件的主要功能有：1）可实现基于实测点或格网重力异常、高程异常及垂线偏差等数据对重力场模型截断至任意阶次的精度进行评估;2）可实现利用重力场模型计算任意点或格网（SRTM地形表面）重力异常、高程异常及垂线偏差等重力量;3）在全球范围内,可按照一定的格网间隔（如1°×1°）对不同重力场模型所表示的重力量（如高程异常等）按不同的阶次进行比较;4）重力场模型格式转换、阶方差分析及RTM重力量计算的数据预处理等。 相似文献

We investigate the influence of low-frequency Rossby waves on the thermal structure of the upper southwestern tropical Indian
Ocean (SWTIO) using Argo profiles, satellite altimetric data, sea surface temperature, wind field data and the theory of linear
vertical normal mode decomposition. Our results show that the SWTIO is generally dominated by the first baroclinic mode motion.
As strong downwelling Rossby waves reach the SWTIO, the contribution of the second baroclinic mode motion in this region can
be increased mainly because of the reduction in the vertical stratification of the upper layer above thermocline, and the
enhancement in the vertical stratification of the lower layer under thermocline also contributes to it. The vertical displacement
of each isothermal is enlarged and the thermal structure of the upper level is modulated, which is indicative of strong vertical
mixing. However, the cold Rossby waves increase the vertical stratification of the upper level, restricting the variability
related to the second baroclinic mode. On the other hand, during decaying phase of warm Rossby waves, Ekman upwelling and
advection processes associated with the surface cyclonic wind circulation can restrain the downwelling processes, carrying
the relatively colder water to the near-surface, which results in an out-of-phase phenomenon between sea surface temperature
anomaly (SSTA) and sea surface height anomaly (SSHA) in the SWTIO. 相似文献

针对现有GPS海浪测量技术的不足,提出基于TRACK的GPS海浪测量方法,即利用TRACK解得海上载体高精度的垂向位移,经浪潮分离提取海浪信号,采用周期图法估计海浪信号的功率谱,计算海浪要素。利用实测数据进行实验,结果表明,平均波高和平均周期与测波仪结果差异分别小于2 cm和0.25 s,验证了本文方法的有效性。 相似文献

利用RTK进行多波束水深测量时,GPS高程在提供瞬时垂直基准方面起着重要的作用。海上实际作业过程中,GPS信号经常会发生失锁现象,造成部分历元高程数据突变,导致海底地形失真。该文以茂名某项目为例,首先介绍了根据EGM2008大地水准面模型,利用高程拟合法将多波束水深测量时GPS椭球高转换为正常高的方法;然后针对GPS信号失锁现象,提出了利用RTK高程中的固定解来求算海水潮位面的方法,同时阐述了该方法的优势。 相似文献

为编制湖北省地壳垂直形变图,收集了自1927年至1986年施测的一万多公里的水准测量资料,并从中筛选出可信度高、复测间隔年限长的七千余公里Ⅰ、Ⅱ等水准测量成果,经正高与重力等项改正后,参加全国水准网伪逆整体平差,求得湖北境内各水准点的垂直运动年速率,据此绘制速度等值线图。该图基本上反映出省区地壳东降西升的继承性新构造运动;黄陵背斜相对于江汉与秭归盆地继续呈上升趋势;等值线走向与断层走向大致相吻合。该图为判别地壳稳定性和断层活动规律提供了重要参考资料。 相似文献
