| 摘要: |
| 中尺度涡在大洋中普遍存在,研究发现其能量比大尺度海洋环流的能量大一个量级,在海洋物质能量输运和全球气候变化中起着重要的作用。受观测条件限制,目前对中尺度涡的观测主要通过卫星高度计实现,只能从海面高度来推算中尺度涡大小、分布、强度及其伴随的水体和能量输送,而卫星高度计对中尺度涡垂直结构特征认识不足,也导致了对中尺度涡所引起的上层海洋能量、热量输送估计误差偏大。目前对中尺度涡三维结构观测认识不足,展望未来将会出现基于无人船平台的大洋中尺度涡三维结构自动观测系统,该平台将集成自动水下剖面观测功能等先进技术,以便观测中尺度涡的垂直结构特征及其时空变化特征,进而可对中尺度涡带来的物质和能量输送进行系统认识。 |

| Abstract: |
| Mesoscale eddy is ubiquitous in the world ocean. Its energy is an order of magnitude larger than the large-scale general ocean circulation playing an important role on the mass and energy transports, and global climate change. Due to lack of in-situ observations, eddies are mainly observed by utilizing satellite altimeter data. Its size, distribution, intensity, and mass and energy transports can also be estimated based on sea surface height data. However, the vertical structure of the mesoscale eddy can’t be captured by remote sensing, which led to large error for estimation of heat and energy transports by mesoscale eddy. Now we know little about the three-dimensional structure of the mesoscale eddy. To design an unmanned observation system to investigate the three-dimensional structure of the oceanic mesoscale eddy is necessary. This system will integrate and apply the advanced technology (such as unmanned ship platform, ocean automatic profile observation) to observe the three-dimensional structure and temporal-spatial variation of the mesoscale eddy, which will enhance understandingSof the material and energy transfer by the mesoscale eddy. |
