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。

The shock wave has made a nearly standard dodecahedron pattern on the surface of centre sphere. This pattern is the result of shock waves interaction from two adjacent detonating spots, and its position shows how the detonating of two adjacent spots acts, synchronized or not. The nice dodecahedron stroke patterns on the surface of recovered centre sphere indicate that this detonating method has good synchronization and spherical converging shock-wave.

The frontogenesis process involves in the interactions among the systems of multiple scales. Since the hardness of the nonlinear problem, it is difficult to study frontogenesis analytically. The introduction of the effects of orography, friction and diabatic processes generally makes impossible the analytical resolution of the problem and leads to the use of numerical models. Primitive equations are numerical integrated together with a detailed description of physical processes. The circulation obtained is then used to diagnose and test theoretical mechanisms. It should be noted, however, that a fully description of frontogenesis in explicitly resolving the of large-, meso- and micro-scale flow in the same framework is not yet possible because of the excessive computer capacity and the time required. In order to deal with the problem, the action of large-scale background has been simplified and taken into consideration through the addition of the forcing into the nonhydrostatic cloud model.

大气锋生是一种多尺度相互作用的过程，理论研究遇到非线性的困难，在考虑地形、摩擦、非绝热等物理过程之后，解析研究更加棘手，通过数值模拟搞清其中的物理机制是重要的研究手段，但是把大、中、小尺度甚至微尺度的系统及其相互作用过程在一个模式里同时模拟好仍然受计算机速度和容量的限制，本论文在非静力云模式中通过强迫方式加入大尺度变形场的作用，在考虑到大尺度背景作用的同时，可以充分利用云模式所提供的丰富物理过程、非静力和高分辨率特点，开展一些过去较难进行的研究工作。

The reasons of our choice are:(1) the coupling of the electromagnetic field with the matter is universal and there is already some experiences with such a kind of field in the literature;(2) the pion is the lightest hadron and its interaction with other fields are known to some extent. The pion fields have been treated as external fields but the discussion is not comprehensive in the literature.

我们选取这样的外场的理由如下：(1)电磁场与物质相互作用的耦合常数是普适的，而且文献中已经有把电磁场当作外场来处理的经验；(2)π介子是最轻的强子，它与其它场的相互作用人们已经有所了解，文献中也有把π介子场当作外场来处理的例子，但讨论还不够深入。

We take sech form ansatz and solve the CNLS equations through variational approach. We obtain the analytical expression of nonlinear coupling term, which is in the lagrangian of CNLS. We apply a potential well model to analyze the interaction properties of self-trapping beams in detail, the results show that the interaction do not change the profile of the beams, two beams keep oscillating around their collective center periodically. The amplitude and period of this oscillation are both determined by initial separation of two beams.
