基于区域滤波的GOCE稳态海面动力地形和地转流
地转流 频域法 漂流浮标 滤波尺度
font style='font-size:12px;'>
2015/6/4
基于频域法,利用最新的GOCE卫星重力场模型和卫星测高数据计算了稳态海面动力地形.结合海洋表层漂流浮标的观测结果,对稳态海面动力地形进行了最优空间滤波尺度分析,给出了区域、纬度带和全球稳态海面动力地形的最优空间滤波尺度因子.在此基础上,给出了全球和区域地转流.结果表明:在中高纬度和全球区域,可以分别获得空间尺度优于102 km和127 km的稳态海面动力地形信息.与海洋表层漂流浮标对比可知,在强流...

秋季北极海冰与欧亚冬季气温在年代际和年际尺度上的不同联系
秋季北极海冰 冬季欧亚低温 年代际 年际
font style='font-size:12px;'>
2015/5/26
北极海冰的急剧消融在近年来欧亚大陆频发的低温事件中扮演着关键角色.秋季北极海冰的偏少对应着冬季欧亚大陆的低温天气,然而二者的联系在年代际和年际两种时间尺度上存在显著区别.本文运用1979—2012年哈德莱中心第一套海冰覆盖率(HadISST1)、欧洲中心(ERA_Interim)的2 m温度、风场、海平面气压场、高度场等资料,分别研究了年代际和年际时间尺度上前期秋季北极海冰与欧亚冬季气温的联系.结...
