Existing research results in various oceanatmosphere coupled models are comprehensively analyzed based on three aspects: the impact of SOFF on global thermohaline circulation and sealevel change and the propagation path of anomalous signal induced by SOFF. A wide range of different viewpoints on the SOFF are summarized; controversial questions are discussed and valuable research directions in the future are suggested. Furthermore, a perspective on the research prospect of this topic under global warming is provided.

从南大洋淡水通量异常对热盐环流和海平面变化的影响以及异常信号传播路径等3个方面系统分析了各种海洋-大气耦合数值模式的已有研究结果，总结了与这一问题有关的各种不同学术观点，对目前存有争议的问题进行了讨论，并对未来有价值的研究方向和全球变暖背景下这一问题的研究前景进行了展望。

Further, we investigated the possible impact of SDP on ENSO event in interannual scale by researching the anomalous characteristics of sea temperature, wind, convergence and divergence, total cloud amount, radiation and so on. The results showed that the influence of SDP on ENSO involve not only the process of positive and negative air-sea feedback, but also the interaction between atmospheric circulation over tropical and subtropical, specially the eastward propagation of anomalous zonal wind from the equatorial Indian Ocean to the Pacific Ocean. Otherwise, it also relates, to some extent, to the transition of large-scale climatic mean flow over the Indian Ocean and Pacific Ocean.

进一步，本文通过分析SDP事件前后期海温、高低层风、低层辐合辐散、高空云量和辐射等的变化特征研究了南印度洋偶极型海温异常在ENSO事件中的作用，结果表明：SDP在ENSO事件中的作用不仅涉及海气相互作用的正负反馈过程，还与热带和副热带大气环流之间的相互作用有关，特别是与东南印度洋海温变化所引起的异常纬向风由赤道印度洋向赤道太平洋传播的过程等有十分直接的关系；同时，SDP对ENSO事件的影响在很大程度上还依赖于大尺度平均气流随季节的变换。

In those years, anticyclone circulation prevails in Northern China with ridge to the western side of Beijing.

北京及附近地区位于低压槽区或处在东高西低的下游"阻塞"形势，是北京夏季多雨的基本环流条件。

The results show that the seasonal variations of the centers of both the SAH and the anticyclone are obvious and in consistence with each other.

结果表明，100hPa高压环流中心有明显的季节分布特征，其中心经度的主频区与100 hPa南亚高压中心经度的主频区位置较为一致。

The seasonal, interannual and interdecadal variations of the 100 hPa anticyclone and the easterly current are analyzed by using the NCEP/NCAR reanalysis data and comparison with that of the 100 hPa South Asian High .

利用NCEP/NCAR再分析资料，分析了中低纬地区100 hPa高压环流和东风气流的季节、年际和年代际变化，并与南亚高压的相应变化进行对比分析。

However, several smaller cyclonic and anticyclonic systems appear in the larger couunterclockwise circulation.

但在其表层海盆尺度的气旋式环流内部还存在小的气旋和反气旋流环。

It is shown that over the top layer of a heating region, although there is no diabatic heating, but still exist ascent, divergence, anticyclonic circulation, and cold center.

在加热区的上空尽管非绝热加热为零，仍然存在上升、辐散、反气旋环流及冷中心，证明这是由于"过流"引起的。

Correspondingly, a mean decrease of 1.0m in sea ice thickness from 1970s to 1990s. The simulated general circulation in Canada Basin is strong anticyclonic ocean surface current, and there is a Transpolar Drift Stream.

北冰洋和北大西洋海冰的漂移速度和方向的特征主要有：在加拿大海盆区常年存在着明显的反气旋式的海冰环流型，并且有明显的穿极漂流，漂移的速度一般在2-5cm/s。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
