Time-dependent variations of the Earths spin axis are excited by various mechanisms.Among the causes referred to commonly are:(1.) tidal forcings by astronomical bodies,(2.) atmospheric circulations,(3.) melting of large ice masses,slow movements from mantle convection and(4.) extremely large earthquakes.

本文选择了12个个例,分析了冷涡区域海表面温度(sea surface temperature,SST)对热带气旋(tropical cyclone,TC)的响应.在TC的影响下,冷涡区域SST降低的最大值在2.7°C-9.15°C,冷涡平均降温1.35°C5.89°C.冷涡SST降低与TC移动速度有很好的反向关联,移动速度越慢,冷涡SST降低越多.冷涡SST降低与TC平均最大风速有较好的正向关联
The Northern South China Sea Shelf-sea (NoSoCS) Study was initiated in 2009.The Shelf-sea has been sampled three times: in June 2010 (summer), December 2010-January 2011 (winter), and December, 2011 (

台湾南部大鹏湾是属于热带半封闭性潟湖,在近十几年来经历了许多重大的转变,从早期2002年之前满布蚵架养殖期间,2003年蚵架完全拆除后,至近期进行国家风景区之建设工程期间等,对水域生态环境亦造成显著的影响.本研究于三个重要时期:1999～2001年满布蚵架养殖期间、2003～2004年蚵架完全拆除后、及2009～2011年国家风景区施工期间,于大鹏湾湾内进行水文监测及浮游生物采样调查.结果发现蚵架
本文首先利用HYCOM模式对太平洋海域气候态模拟结果,分析描述了太平洋海域赤道流系的流系特征.然后使用1995至1998年间的HYCOM实时模拟数据研究了这一流系在这期间的变化,以探究1997 El Niño年期间赤道流系的变化特点.结果表明HYCOM模结果能很好的模拟出赤道流系的相关信息;分析还发现赤道流系的表层和次表层在1997年El Niño事件前后一段较长的时间
It is well known that the solution of linear shallow-water equations subject to the boundary conditions consists of incoming and reflected Kelvin waves as well as one or more Poincare modes. Generally
