简介：以前的学习来到结论：基于南方亚洲人高度(SAH)的异例，在热带、副热带的区域上的100-hPageopotential高度，和100-hPa循环，我们能在长江山谷和诺思中国预言降水异例。测试它的有效性，一系列实验被设计了并且操作，它包括控制实验，敏感实验(它增加了异例进100-hPageopotential高度和风地)，并且四合成的实验。基于象EPR-CF，EPRCD，EPR-HF，和EPR-HD那样的镇静的起始的领域试验，能在长江山谷和诺思中国复制洪水或干旱。它建议在热带、副热带的区域上的SAH，100-hPageopotential高度，和发行量的异例可以可能在二个区域暗示夏天降水异例。SAH，100-hPageopotential高度，和西南的异例流动在以前的时期的敏感实验结果表演是干旱或洪水的一个信号在长江山谷和诺思中国的下列夏天。并且它也是在二个区域在夏天降水异例上有影响的因素之一。100-hPageopotential高度并且SAH和西南流动的异常加强的积极异例将在诺思中国在长江山谷和干旱导致洪水；当100-hPageopotential高度并且SAH和西南流动的异常变弱的否定异例将在诺思中国在长江山谷和洪水导致干旱时。[出版摘要]

简介：以前的研究建议在北热带大西洋(NTA)上的春天SST异例影响热带气旋(TC)在在下列夏天和秋天的西方的诺思太平洋(WNP)上的活动。现在的学习表明在春天NTASST和后面的夏天秋天WNPTC开始频率之间的连接不是静止的。后面的夏天秋天WNPTC开始频率上的春天NTASST的影响是在前弱、不足道，却在以后强壮、重要，1980年代末。在1980年代末前，在热带中央太平洋的NTASST导致异例的SST异例是弱的，并且在WNP上的大气的循环的反应不是强壮的。作为结果，在春天NTASST和后面的夏天秋天WNPTC开始频率之间的连接在以前的时期是不足道的。在1980年代末以后，相反，NTASST异例通过大西洋和平的teleconnection导致显著热带中央和平的SST异例。热带中央和平的SST异例进一步为WNPTC开始导致有利条件，包括垂直运动，中间水平的相对湿度，和垂直的带的风砍。因此，在NTASST之间的连接和WNPTC开始频率在最近的时期是重要的。进一步的分析证明interdecadal在在春天NTASST之间的连接变化，后面的夏天秋天WNPTC开始频率可能与在NTA区域上的climatologicalSST变化有关。

简介：关于在在中国的纵贯的地震的带和基于地理信息，系统(GIS)被做了的中央orogenic带的连接区域的差错和seismicity之间的关系的研究。为每在这个区域的16个差错，我们造一个25km缓冲区地区和使用覆盖分析在每个差错上调查seismicity和它的特征。结果作为follows:the揭开主要地震差错西方的片断西方Qinling差错，Lixian-Luojiabao差错的西南的片断，Lintan-Dangchang差错的东南的片断，Wenxian差错的西南的片断，Huya差错，和Xueshan差错北边。最活跃的差错是Huya和Xueshan差错，然后，Tazang差错，Lixian-Luojiabao差错和Guanggaishan-Dieshan的北山麓指责。研究地区能根据焦点的深度被划分成四个区域，它向南向北变得更深从到。焦点的深度的侧面显示几何学和差错的机械性质，并且进一步揭示西藏的高原的东方挤出和群众的向东南的逃跑的运动模型，因此在这个区域对地震和危险缓解为保护提供基础。

简介：通过从CMIP3和CMIP5收集的联合模型模拟和设计的整体的分析，我们证明基本空间规模限制可能在气候模型预言和设计的有用另外的精炼不能在哪个下面是可能的下面存在。那限制在气候变量之中并且从区域变化到区域。我们证明在表面温度预言的无常(噪音)(在全球气候模型模拟的一个整体之中由传播代表了)通常在整个北美洲在1000km下面在水平规模超过整体平均数(信号)，在那些规模暗示差的可预测性。更多的有限技巧为地区性的降水的可预测性被显示出。在这种情况中的整体传播趋于在2000km下面为规模超过或等于整体平均数。这些调查结果热点在预言地区性特定的未来气候异例的挑战，为特别，hydroclimatic影响例如干旱和湿。
