| 摘 要： | 南极海冰是全球气候系统的重要组成部分。不同于北极海冰的快速减少，近40年来，南极海冰范围在2014年前是缓慢增加、后是突变减少。单一的大尺度大气环流因素无法解释南极海冰的长期变化趋势，海洋?大气相互作用对海冰的耦合影响还未得到充分研究。受南极海冰厚度遥感观测和数值模拟能力所限，现有数据仍无法准确量化全球变化背景下南极海冰的厚度和体积变化；目前南极海冰变化的气候效应还未充分明确。当前国内外对南极海冰研究的不足迫切要求发展长期可靠的南极海冰厚度数据，以突破南极海冰体积变化研究的难题，同时应综合考虑多气候模态和海气系统耦合的作用，研究南极海冰变化的机制及其气候效应。

A review on Antarctic sea ice change and its climate effects |
| |
| Abstract: | Antarctic sea ice plays an important role in the global climate system. In contrast to the rapid decrease in Arctic sea ice extent, Antarctic sea ice extent exhibits a gradually increasing trend before 2014, followed by an abrupt decline in the last four decades. A single large-scale atmospheric circulation cannot fully explain the long-term trend of Antarctic sea ice, and the coupling influence of ocean-atmosphere interactions has not been sufficiently investigated. Limited by the capabilities of remote sensing and numerical simulation, the Antarctic sea ice thickness and volume variations in the context of global change cannot be quantified precisely with currently available sea ice thickness and volume data. Moreover, the climate effects of Antarctic sea ice change require further investigation. Hence it is strongly urgent to develop a long-term and reliable Antarctic sea ice thickness data set to quantify the Antarctic sea ice volume change. Meanwhile, the influences of multi-climate modes and ocean-atmosphere coupling system on the Antarctic sea ice changes should be considered comprehensively. |
