结果表明，在中高层出现"北槽南涡"的环流形势场有利于登陆台风的维持；源于南海南部和孟加拉湾的热带低空急流汇成的台风南侧的西南风急流是台风登陆后得以维持和引发暴雨增幅的重要系统。

It is shown from this thesis that flow fields on synoptic maps can be decomposed into rotation and deformation fields. Geostrophic non-frictional cyclone and anticyclone vortex patterns are closed circulations around the center point, streamlines of frictional cyclone and anticyclone patterns have spiral forms around the focus point. Saddle fields have four vortex centers (two cyclones and two anticyclones) and a saddle point. Blocking high pressure and cut-off low pressure patterns consist of a vortex center and a saddle point.

Observation of radar and intensive surface wind of 0505 typhoon Haitang is used to analyze the relationship between radar reflectivity and observed precipitation and the relationship between mesoscale surface stream field and heavy rainfall. The analysis shows that when the Doppler radar reflectivity reaches 50 dbz, it has a good correspondence to the heavy one hour precipitation. Besides, heavy precipitation is also related to the mesoscale cyclonical current and confluent currents, it occurs near the mesoscale cyclonical or confluent current appearing at the same time.

利用严重影响浙江东南地区的2005年05号台风的雷达和地面加密风场资料，分析对比台风中尺度暴雨过程中雷达回波与实况降水、中尺度地面流场与暴雨之间的关系，结果得到：多普勒雷达近地面强回波带或中心往往达到50 dbz时，与一小时的强降水区有很好的对应关系，暴雨中心区也与地面加密的中尺度流场中出现的中尺度气旋性环流和汇合气流有关，强暴雨区落在同时刻中尺度涡旋或汇合线附近。

It was shown that, the flow pattern in the EMPT was more complex than that in traditional one, that is, in the column chamber, the short circuit flow from the outlet nozzle of the ladle was depressed by the rotating molten steel, and horizontal recurrent flow appeared in rectangular chamber, which prolonged the average staying time of the molten steel, then reduced the volume fraction of inactive area in EMPT.

结果显示，电磁净化中间包的流场比传统中间包的流场复杂：在圆形腔中，旋转运动抑制了大包水口至矩形腔的短路流，而在矩形腔中形成水平环流，从而延长钢液在中间包的平均停留时间，死区减小，电磁净化中间包的上述流场结构及传输行为对钢液中的非金属夹杂物去除非常有利。

Casethat begin transformation but do not become embedded in the baroclinic zone fail to complrte transformation and simply dissipate over lower sea surface temperatures.1at transformation stage,there are two features in 500mb analysis aKOPPU s surface center is located beneath concentric,closed 500mb contours and is equatorward of 5820-m contour associated with a short-wave trough to the northwest of strom bthe closed contours associated with KOPPU 24h earlier have combined with approaching 500mb trough so that KOPPU appear to be in an open wave.furthermore,streamlines associated with this short wave trough have wrapped around the circulation of KOPPU,which indicated that KOPPU has become embedded in 500mb westerlies.

台风变性分为两个阶段：变性阶段和再加强阶段；变性的开始和结束以热带气旋环流和先前存在的中纬度斜压带相互作用为基础，KOPPU嵌入先前存在的中纬度斜压带且风暴中心在冷下沉气流中，而KETSANA没有嵌入先前存在的中纬度斜压带则没完成变性只是消散在低的海平面温度(1)台风变性阶段在500hPa高度场分析中有两个重要特征：a首先风暴中心是闭合的等值线并和风暴中心西北的短波槽相关；随后闭合等值线靠近500hPa槽，因此风暴闭合中心消失，风暴位于开波中。b而且和短波槽相关流线缠绕在风暴中心，结果风暴在西风带中。

The tripolar structure SST anomalies over the North Atlantic, which also appears at the interannual scale with a spectral peak at 3—4 years, are mainly resulted from the barotropic driving of the NAO like atmospheric forcing, and thermal process plays a dominantrole in this process. When the NAO is strong, the westerly weakens over the midlat itudes; both the sensible and the latent heat flux release from the ocean tend to decrease, which warms the ocean and leads to positive SST anomalies. Over the sub polar region including the Labrador Sea, a stronger NAO is associated with a deeper Icelandic Low; the high latitudes originated colder air then blows over the ocean surface, the air-sea temperature difference become larger, and the se n sible heat flux loss from the ocean increases, which subsequently leads to colder SST anomalies.

分析表明，模式中三核型SST异常的产生，主要来自大气的强迫，NAO增强，中纬度大洋上的西风减弱，海洋感热和潜热通量损失减少，中纬度大洋得到的净热通量增加，导致SST出现正距平；在包括Labrador 海在内的副极地大洋，NAO增强、冰岛低压加深，气旋性环流增强，来自高纬度的冷空气吹过洋面，海气温差加大，大洋的感热通量损失增加，SST降低。

Accordingly, aromatic compounds can be divided into three groups and a delocalized π system itself is always destabilized, the dependence of aromatic ring current upon the CT was reveled, and ring rigidity has been defined as a new aromatic index.

据此，我们提出了芳环化合物新的分类准则，揭示了芳香环流起因的必要条件，定义环的刚度为芳香性一个新判据。发现，分子内基团间的局部作用同它们对分子整体性能的影响是完全相反的。
