台风

Chen et al noted that there are three kinds of landfall typhoon tracks; subtropical high and polar front, whose evolutions and adjustments may modify typhoon movement, are the main synoptic systems which influence the track of landfall typhoon.

陈联寿等根据(1949-1976)年资料，指出：登陆台风路径可分为三类；副热带高压和极锋是影响热带气旋陆地路径的主要天气系统，它们的演变和调整会影响热带气旋的移向。

The diagnosis of typhoon secondary circulation is carried out in terms of the SawyerEliassen secondary circulation euation version of the primitive equation model with the aid of the composite field of five offsea typhoons in explosive development.

利用原始方程模式的Sawyer－Eliassen次级环流方程，对由5个爆发性发展的台风所合成的要素场进行了次级环流的诊断。结果表明，在各强迫项中，地转形变和非绝热加热强迫作用较大。

During the four years study on the project, we develop a dynamical forecast model that describing the subtropical ridge surface. A new theory on the role of the land-sea thermal difference on the formation of the Subtropical High is advanced. It is concluded that in the summer subtropics over each continent and its adjacent ocean LO, SE, CO, and a double-dominant heating from west to east compose a LOSECOD heating quadruplet. The influence of the Eurasia continent on SH varies according to the seasonal variation. From the ideal numerical simulation it is shown the important role of the Eaiuan continent and the huge topography on the mechanism of formation and mantanence of the SH during the summer. It is verified by the numerical simulation that the extension of the subtropical continent into the tropics greatly enhances the " East Asian monsoon". Through the Rossby energy dissipation theory it is verified that the deep latent convective heating induces the onset of the South China Sea monsoon over the Bay of Bengal. The relationship and mechanism between the precipitaiton over the East Asia and the Subtropicla high is illustrated by the data. It is also found the close phase lock between the east-west shift of the SH and the disturbence of the east wind belt over the tropical troposphere. The interaction between the structure and activity feature of the SH and the Meiyu over the Yangtze-Huaihe river valley is revealed from the data. The numerical simulation verified the impact of the different SH pattern on the path of the typhoon.

本项目的研究发展了描述副热带高压脊面变化的动力模型，提出了夏季副热带地区四叶型非绝热加热分布型及相应环流拼图的创新理论；明确了大陆尺度的海陆热力差异在副热带高压形成中的作用；指出欧亚地形对副热带高压和气候的影响随季节变化而变化，通过数值试验证明春季青藏高原的感热加热对亚洲夏季风的爆发地点起了"锚定"的作用，进一步证实了副热带高压断裂和亚洲夏季风的最早爆发地点发生在孟加拉湾东岸；利用Rossby波能量频散理论证明了孟加拉湾深对流潜热释放诱导南海季风爆发的机制；揭示了东亚季风降水的季节内变化与西太副高的关系及机理；揭示了西太副高与东西风带中扰动之间的相互作用过程，指出西太副高的东西活动与热带对流层上空东风带扰动和中纬度西风带扰动的移动和锁相密切相关；研究了夏季淮河流域梅雨期间副高结构和活动特征及其与江淮暴雨的相互作用；验证了不同副热带高压形态对台风路径的不同影响；通过数值试验证明了欧亚大陆和青藏高原等大地形对副热带高压形成和维持的重要作用。

The locomotive direction of typhoon was the same with that of the most intense spiral rainband.

食指状和"人"字形的外螺旋雨带、螺旋雨带最大回波强度区的移动与台风前进方向一致。

Typhoon moved toward the orientation where the forefinger and man grapheme spiral rainband outside.

台风形成的不对称结构影响其移向和降水分布，路径突转时极易产生短时强降水。

Satellite imagery is a good tool at present, this paper analysis satellite imagery and summrize feature:use a few simple sentences:aa marked decrease of deep cloudiness and rainband outside the inner core in the western quadrant,the result is an asymmetric appearance of clouds and deep convection compared to the moresymmetric structure during the mature stage of tropical cyclone.

同时对云图上的特征分析总结，分析结果表明：(1)云图上看：热带气旋变性。用几个简单的语句依次概括为：a云和深对流在东西两边的非对称性，并伴随着南边的"干缝"出现。b北边和西边"盾状"卷云的出现c台风眼墙消失产生"干缝"，冷暖锋的出现。

However, the regional distribution of rainfall is not greatly different and the damage from typhoons is minimal.

但地区性降水分布差异不大，给韩国所有地区造成许多损害的台风对忠北的影响较小。

When the shear is weak, the rainfall distribution is more symmetric.

而环境垂直风较小的台风，其风左右侧之雨分布较为对称。
