台风

与 台风 相关的网络例句 [注:此内容来源于网络,仅供参考]

In Taiwan area often have typhoon attracting during summer times. Typhoon brings abundant rainfall and the rainfall concentrates to the river, naturally washes out the main channel and the river high alluvion. When flood retreat, the exposed high alluvion can be widely used. Agriculture, plant and wetland, these places can increase zoology. On the other hand ,they baffle current of water flow. So this research focuses on different arrangement of flexible vegetation.

中文摘要因为台湾地区因气候关系常有台风侵袭,台风来临时带来的充沛雨量集中到河川,自然冲刷出主河道和高滩地,当洪水退去时,裸露的高滩地即可以广泛地被利用,有许多的人为开垦、种植,但是这些植生有增加动植物栖地的益处,另一方面也会产生阻碍水流的害处,所以本篇对於不同布置方式的柔性植生做流场的研究。

The climate characteristics of TCP were analyzed with variance analysis,trend coefficient and linear regression technique,followed by comparison with those of annal total rainfall in East China.Results show that the spatial distribution of TC rainfall is not uniform in East China with the...

结果表明:华东地区登陆台风降水量空间分布不均匀,福建东南沿海地区最大,具有向西北方向递减的趋势,这种趋势与地形等因素有关;TCP的年际变化明显,9 a和15 a周期显著;TCP年代际变化表现为20世纪50年代最多,70年代前开始减少,比华北地区台风降水减少出现的时间提早10 a;TCP与总降水两者的时间演变特点差异较大。

According to the data of tropical cyclone landfalling in China for 1949-2006, climatologically statistical parameters of typhoon season, including the first-landfall TC date, the last-landfall TC date and the duration of typhoon season were analyzed.

利用1949—2006年登陆中国的热带气旋资料,分析登陆 TC 台风季参数的气候特征,结论如下:1 登陆中国的初旋①以南海生成为主(占5成半),终旋以西太平洋为主(高达8成),近50多年来初、终旋源地分别呈现向东北、西北移动的趋势;2 广东初旋最早,广西、浙江终旋较早,广东台风季最长。

In recent 20 years,the research on TC and typhoon climatology has become one significant aspect of TC field and made great progress.

近20年来,对热带气旋和台风活动的气候学研究成为台风领域的一个重要研究方向,并取得了显著的研究进展。

This paper proposes a new probability model-Multivariate compound extreme value distribution to predict 'typhoon-induced rainfall for the Wenzhou City in Zhejiang Province.

作者采用多维复合极值分布理论(Multivariate compound extreme value distribution),以受台风暴雨危害较严重的浙江温州地区为例,对台风诱发暴雨的降水量进行了概率预测。

It is showed that, the orientation of the outer long cloud band involved usually indicates the future moving direction of typhoon.

尤其是台风南部来自SW-S-SE方向的季风汇合带云带,不仅意味着台风强度的加强和维持,更预示着台风将往北移动。

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.

在假设台风环流存在最大风速半径的前提下,利用多普勒雷达径向速度场的这种分布特性和型态识别技术,进行近海台风的雷达定位客观方法的应用研究,并选取两种客观定位方法对台风中心位置进行估计。

" 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。&

Simulation of a typhoon case presents assimilating radar data advanced prediction of typhoon precipitation, intensity and track, enhanced the meso-P scale system on typhoon spiral rain-band.

4登陆台风试验结果表明同化雷达资料可以提高台风降水、强度和移动路径的预报水平,并改善初始场中台风螺旋雨带上的中-β尺度对流系统的结构。

4Ac cording to thehistorical data of serious typhoon disasters in Zhejiang and the analysis of grey catastrophic forecast, it is known that the first,second and third years of serious typhoon disasters in Zhejiang will appear in 2001, 200 4 and 2008, and the latter two yearsare approximately in conformity with the pe ak and valley years of the 23th period of sunspot activity.

根据浙江历史上的台风重灾年资料,利用灰色灾变预测分析,可得浙江未来第一、第二和第三个台风重灾年分别为2001、2004和2008年,其中后两个台风重灾年与太阳黑子活动第23周期的峰年和谷年是大致吻合的。
