简介：这研究介绍一个新方法识别敏感区域，它由为台风调用潮湿的潜在的涡度(MPV)的否定异例是坚定的适应观察。否定MPV的区域是对称的不稳定性区域并且能为台风作为敏感区域被拿，这被发现适应观察。在2008的三台风，Nuri，Fung-wong，和Fengshen，在MM5的帮助下被模仿模型。这些台风很好在开始的12个小时被模仿，这被显示出。把调查基于这些，MPV的计算顺序被执行。结果证明MPV的否定最大值总是绕为所有盒子的台风眼睛，它意味着敏感区域总是也在他们附近。

简介：潮计量器的高度变化直接影响海平面观察。为在大区域或地球的海平面变化的研究，陆地竖直位移必须被考虑。在2001和2003的GPS和绝对重力观察的二个会议被用来在ITRF2000和欧亚大陆框架决定中国海岸的水平、垂直的运动。在连续观察和周期的观察的结果之间的Thedifference被讨论。

简介：越过在为印度尼西亚地震的印度尼西亚下面的地球结构的S波浪速度通过震动图分析被调查了，同时在时间领域和三个笛卡儿的部件。数据在DAV观察车站被记录，菲律宾。主要数据集合是震动图比较在之间测量并且合成震动图而不是旅行时间数据，当通常在另外的地震学上的研究使用了。合成震动图用GEMINI方法被计算，它在一种古灵长类动物的全球地球披风给背离合成震动图并且更早有的震动图比较表演上面等价于模式Summation.The到达时间比那些测量。在上面的披风层的h的坡度被改变进在一种古灵长类动物模型说了的一个积极，而非否定的斜坡，并且否定修正在所有地球披风层被强加到多项式的系数的零份订单。优秀试穿，以及旅行时间或波形，从爱和瑞利，的表面波浪被获得表面象核心一样向S和SS披风波浪招手地球披风分开的反映的waves.This结果快车，由于在印度和亚洲之间的碰撞构造释放地区，地球披风层在所有在S波浪速度和垂直anisotropy有一个否定异例。
