查询词典 typhoon

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。

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。

Typhoon Nanmadol made landfall on Taiwan on December. The outer rainband of typhoon combining with northeasterly monsoon induced strong reflectivity. When Typhoon Nanmadol left Taiwan, reflectivity dissipated rapidly because of incursion of drier and colder air.

月份侵台之南玛台风，外围雨带因与东季风共伴而产生强回波，出海后因为东季风较乾的空气侵入，使得台风回波迅速消散。

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。

The fifth typhoon named HaiTang landed in Fujian in 2005, then it moved to northwest. During this movement, there was a mesoscale convective cloud increasing quickly, within the periphery of cloud cinctures of typhoon connected with tropical convergence cinctures. And the MCS caused heavy rainf all in the eastern and northern part of Wenzhou, which made the more dangerous weather than typhoon. In a word, it was important to research the developmental mechanism of MCS, for the new discovery could contribute to forecasting rainstorm caused by the landing typhoon in the future.

2005年05号台风&海棠&登陆福建后，在外围云系里有个明显发展的中尺度对流云团经过温州东部及北部地区，引起了强降水，从而造成比热带风暴环流本身更具破坏力的强烈天气，因此研究台风内中尺度对流系统的发展机制能够为预报台风灾害提供依据。

The various forms coalesced and finally became typhoon.

各种形式合并在一起最后变成了typhoon

Being different from previous studies, global positioning system Dropsonde data collected during the Dropwindsonde Observations for Typhoon Surveillance near the Taiwan Region were chosen to study the thermal and dynamic structure for its two typical periods of life. Two surveillance flights were carried out throughout its lifetime.
