The Antarctic Circumpolar Current (ACC) is a global circulation that flows from west to east around the lines of latitude, across the Pacific, Atlantic and Indian Oceans, and is the only current in the world that associates with all other ocean currents. Although the history of ACC observation and research is relatively short, great progress has been made in learning about the characteristics, change and mechanism of ACC. Research into its role in global change is becoming more intensive, and now represents a frontier in the field of ocean and atmosphere studies. A summary of ACC observations and theoretical research results over the past few decades, including front distribution, flow characteristics, zonal transport, meridional transport, and their corresponding dynamic mechanisms, has allowed us to determine the weaknesses in our knowledge of the ACC. We make suggestions for related work, which forms the basis of our research into the ACC and related marine and atmospheric processes.%南极绕极流是自西向东横贯太平洋、大西洋和印度洋的全球性环流,也是世界上唯一一支和地球上所有其他洋流都有关联的洋流.尽管对南极绕极流的观测和研究历史相对较短,但是对其特征、变化和机制的研究已取得了许多重要进展,对其在全球变化中的作用的研究也日益深入.南极绕极流成为海洋和大气科学领域的前沿研究内容.以绕极流锋面分布、流速特征、纬向输运、经向输运及其响应的动力机制为重点,总结了过去数十年里对绕极流观测和理论的研究结果,明确了研究中仍然薄弱的环节,并提出了相应的工作建议,以促进我国关于南极绕极流及相关海洋和大气过程的研究.
