台风的

First, the typhoon flow field is decomposed into two parts: the maximum asymmetric vortex and irrotational environmental flow field. Then the maximum asymmetric vortex is also decomposed into two parts: the maximum symmetric vortex and β-gyres. Finally, typhoon Pearl(2006) is simulated by WRF model(weather research and forcasting model), and flow fields at various times at 500hPa...

首先，将台风的流场分解成最大的、不对称的涡旋流场和无旋流场；然后将不对称的涡旋流场分解成最大的对称涡旋和不对称的β涡旋对；最后，利用WRF(weather research and forcasting)模式(V2.1.2)模拟了200601号珍珠台风，并对各时次的500hPa风场用该方法进行分解，结果表明：该方法对台风的运动机理研究和实际的台风路径预测提供了有价值的信息。

First, UWPBL model(The University of Washington Planetary Boundary Layer Model) is used to retrieve typhoon's sea level pressure from sea surface winds data of SeaWinds which aboard on QuikSCAT and these strength results are analyzed. Then the variational method is applied to decompose the sea surface winds field into two parts: the vortex and irrotational environmental flow field, the UWPBL model is used again to retrieve ShanShan and YaGi typhoons' sea level pressure from the vortex flow field, the results of typhoon's central positions are analyzed by comparing the results with the results of direct retrieving, NCEP's data and typhoon annual reports. It turns out that the accuracy of the typhoon's sea level pressure central position has been obviously improved, This method offers a new idea for the study of typhoon from microwave scatterometer data.

本文首先利用QuikSCAT散射计获取的海面风场资料，利用华盛顿大学行星边界层模式对台风海平面气压场进行反演，并对其强度进行了分析；然后对获取的海面风场，采用变分方法对风场进行分解，分解出无旋和有旋风场，对分解出的有旋风场，再利用UWPBL模式对珊珊和魔羯台风的海平面气压场进行了反演，对所得结果与通常直接反演、NCEP海平面气压场及台风报文资料进行一一对比，结果表明：新的反演定位的方法对台风海平面气压场中心气压的定位精度有了大幅度的提高，此种定位的方法为散射计资料在台风中的实际应用开辟了一条新的思路。

The southwesterly low-level jets from the southern South-China Sea and the Bay of Bengal are main systems responsible for the maintenance in intensity of the typhoon and causing the enhancement of the accompanied heavy rainfall.

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。

As Typhon Haitang draws closer to Taiwan, the National Science Counc il sent an airplane to the edge of the storm to test its intensity . They also took video footage of weather conditions at the scene.

趁著海棠台风逼近，国科会补助的「追风计画」今天凌晨又有飞机飞到台风的暴风圈，抛掷探测仪侦测台风结构密度，并且用摄影机拍下台风暴风圈外围的天气状况。

The concept of "typhoon":Some subjects lacked clear concept about the density of isobaric line of the typhoon, and the processing route, the weather situation of the typhoon eye and the icon of the typhoon on the weather map.

认识台风：部分学童对於等压线越密集台风的风速越大，台风的行进路线、台风眼的天气情形以及天气图上台风的图示，均欠缺清晰的概念。

Based on division of regions of a typhoon and characteristic scales of physical quantities done by Anthes,sets of equations governing different parts of the typhoon are derived with scale analysis and wave energy equations for each part are obtained with the WKB method. Discussions indicated that physical factors contributing to typhoon development are unconstant in all parts of the typhoon,respectively shown as vertical changes in vorticity and tangential wind for the core and outer mid-tropospheric area,...

利用Anthes关于台风的区域划分以及物理量特征尺度的结果，采用尺度分析方法导出了台风不同区域的控制方程组，又用WKB方法得到各区的波能量方程并进行了讨论，指出影响台风发展的物理因子在各区的异同点：各区都有非定常因子；同时，台风内核及外围中层对流层的因子有涡度和切向风的垂直变化，外围边界层有热成风及其偏差，外围流出层有水平位温梯度，这些因子与重力波适当的移向相配合，可使台风能量发展，强度增大。

Although the accuracy in meterological forecast of tropical cyclones has been distinctly improved, it is still a difficult problem confronting masters and anti-typhoon team leaders of the companies how to steer clear of typhoon reasonably and safely in case that the actual resistance to typhoon is strong enough, the sea area wide enough, and the time permitting ; to avoid unreasonable deviation,anchoring for shelter, blindly rushing onto her path,being involved in storm area,even into the the center of typhoon; under the limitation of the condition of the sea area and time.how to take correct meassures to escape , such as navigating with wind or windward in bias angle, slowing down, anchoring, berthing alongside the warf, mooring to buoy,etc.

传统的解决办法是，将台风中心的预报位置和本船的船位点绘在《台风位置标示图》上，研究本船与台风的相对位置以及相互间动态的发展态势，考虑各种因素的影响并留有充分余地，在小比例尺海图上用几何相对运动标绘的方法作图绘算出本船应采取的避台航向。本文所讨论的就是为迅速和较为精确地解决以上点绘和相对运动标绘的问题，在考虑了各种因素的影响并留有充分余地的情况下，在全方位范围内搜索安全航向，对本船与台风的相对位置以及两者之间的动态发展态势作出预报，并给出船长最关心的、对其作出避台决策至关重要的一组数据和直观图形，帮助使用者及早制订科学合理的避抗预案，及时果断地采取正确有效的避抗措施，解决避台决策的实际问题而设计的一个计算机标绘系统。

On the basis of the distribution feature and the hypothesis about the radius of maximum wind within the circulation of a tropical cyclone,a lot of methods are designed to decide a tropical cyclone center with the pattern recognition technique.The aim of the applied study in operational tropical cyclone monitoring is to establish some objective positioning methods for the center of a tropical cyclone using a single Doppler radar radial velocity.

" For that records begin at late 90 (19) century we have no record s of two landfalls ( land-falling) in category 5 hurricanes in the same season, nor there are any records of the first two hurricanes of the same season developing in to the category 5 hurricanes."

&自从我们从19世纪开始进行记录，尚未记录到2次5级台风在同一季节登陆，同时我们也没有关于在同一季节，头两次台风就发展为5级台风的记录。&

Main meteorological factors for disaster caused by landfalling tropical cyclones in China are analyzed based on samples formed during 1980-2004. It is shown that the degree of disaster has strong relation with precipitation, gale, and landfalling intensity and position point of typhoon, et al.
