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。

Finally, applications of the anomalous propagation of microwave in tropospheric ducts are discussed: in connection with concrete radar parameters, effects of ducts on radar range and detection performance are discussed, the results obtained are of great value for the overall design of radar systems; by use of the interference standards of ITU-R, the co-ordination area of satellite earth-station under tropospheric ducts environment is studied ; by explaining the relationship between evaporation duct and advection fog, a new way to forecast sea advection fog from evaporation duct is provided.

最后讨论了对流层大气波导环境下电波异常传播特性的应用：结合具体的雷达系统参数，模拟计算了大气波导对雷达作用距离及发现概率的影响，对雷达系统的总体设计具有重要的参考价值；对表面大气波导环境下的卫星地球站通信协调区域进行了确定，从理论上很好地给出了协调距离量级的概念，为卫星地球站与地面微波站之间的协调提供了依据和参考；分析了利用海面蒸发波导来快速预测平流海雾的新方法，完善了平流海雾的预报方法，对海上安全作业和生产具有重要的意义。

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。

From the result of temperature analyzing, the thermocline depth anomaly and heat storage anomalies transmit from tropical west Pacific to east Pacific in equator. The heat storage anomalies in east equatorial Pacific reach its maximum value before west equatorial Pacific.

从温度场的模拟结果看，在赤道区域跃层深度异常和上层海洋热含量异常在厄尔尼诺事件中都是东向传播的，并且赤道东太平洋的热含量异常明显超前于热带西太平洋。

The two small cells born at southeast of Beijing develop rapidly and gradually move northwestward into urban area.

分析还表明，20：00左右的超强雷达回波是由大气异常传播造成的虚假超折射回波。

There exhibited different characteristics in geoelectrical field anomalies, but they were closely related to tidal waves, for example, the increasing in amplitude at semidiurnal and semimonthly periods of tidal ...

分析异常产生机理认为，强震前的这种异常现象是震源区临震孕育过程中岩石弱化产生的电场异常，经自由空间或地壳传播到达地电台站后，与台站记录的电场潮汐波相叠加产生潮汐波增强或减弱现象。

Evidence suggests that when northern snow forced teleconnection is generated in this season, anomalous zonal/meridional circulations are revealed in east Asia-western Pacific band; with east Asia-Pacific teleconnection formed, anomalous zonal circulation is dominant over that band; the anomalous vortex of north Pacific origin moves southwestward and, r...

研究发现当北半球夏季出现积雪强迫型遥相关时，东亚－西太平洋地区既存在异常纬向环流，也存在异常经向环流；而当出现东亚太平洋型遥相关时，东亚－西太平洋地区以异常纬向环流为主。分析还发现源于北太平洋的异常涡旋在向南传播的过程中，先取西南路径，在到达菲律宾东部以后折向东南。

The leading mode of the oceanic surface current anomaly displays an oceanic gyre that is determined by the wind stress anomalies through Ekman relation, while the interdecadal variability in the upper ocean circulation is characterized by changes of the strength of the subtropical and subpolar gyres which lags the wind stress curl anomaly by 5 years.

对印度洋偶极子事件演变特征的合成分析显示，大气异常引起的海洋热容量异常传播在偶极子事件建立和消亡过程中具有重要作用，且这一过程可以独立于ENSO存在：ENSO对偶极子事件的海温变化具有一定的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
