气旋的

The terracedly descending shape in east slope of Tai hang is one of the most important factors that influence the foehn formation in this area.

数值模式的结果部分地证实了阿尔泰背风气旋的气候特征，指出它在生成的初期即已较强，此后不再随时间发展和加深。

Through analysis of potential vorticity in isobaric surface field, in high-troposphere a positive potential vorticity disturbance before rainstorm generation;positive potential vorticity disturbance in high-troposphere downward, form one vertical disturbance column, now corresponding precipitation develop stage;When near ground arises negative potential vorticity disturbance, precipitation also weaken.

通过对等压面的位涡分析，发现在暴雨发生发展时，在对流层高层有正位涡向下扰动，在暴雨的发展鼎盛阶段，从对流层中高层到地面形成一个垂直扰动柱；位涡柱对地面气旋的发展有较好的指示性，位涡柱形成时刻前后降水达到最强；当近地面出现负的位涡扰动时，降水随之减弱。

Based on the monthly mean data of the sea level pressure and the sea surface temperature over the Pacific during the years of 1957-1976, we have calculated the lag correlation between the SST averaged over the eastern equatorial Pacific region (5°N-5°S, 80°-180°w) and the sea level pressure field of the North Pacific.

发现赤道海温的变化，就北太平洋而言，主要是受该洋东南部低层副热带及气旋的控制，而赤道海温对副热带高压的反馈，主要是发生在太平洋中部对流层副热带高压中心附近地区。

PARMA is expected to make landfall at northern Luzon again tonight, and PARMA will decelerate as interaction diminishes.

预料芭玛将於今晚再度登陆吕宋，而随著两气旋的距离逐渐扩大，藤原效应的幅度将会减少。

In addition,the development of vertical motion also improved the cyclonic activity with γ scale,and would strengthen the intensity of precipitation.

同时，垂直运动的发展，促使中γ尺度气旋的活跃活动使得暴雨过程中的降水强度得到显著加强，也是暴雨强度增强的主要原因。

Through the analysis, it is shown that the Matsa s extratropical transition and the re-intensification are due to the intrusion of cold air from the upper-level trough into the typhoon s circulation.

以一个在陆上长久维持并最终演变成温带气旋的登陆台风&麦莎&为研究对象，通过对其北上变性过程的分析发现，台风与中高纬西风槽的相互作用使得冷空气侵入是其变性加强的原因。

The effect of tropical cyclone horizontal scale on its motion is investigated in a nondivergent, barotropic model with no basic flow.

应用无基本气流的无辐散正压模式研究热带气旋的水平尺度对其移动的影响。

Numerical simulation shows that the location and intensity of the modeled high and low pressure centers is consistent with the observation. The pressure gradient intensity of cyclone closes to observation. The regional distribution, transportation direction, centers of the cold, worm advections have similar characters with fact. On the other hand, the temperature stratosphere simulation result is slightly bigger than the fact.

数值模拟结果表明，模拟高压、低压中心位置和强度与实况较为吻合，气旋的气压梯度强度与实况较为接近；冷暖平流在分布区域、输送方向、强中心位置上也与实况具有较相似的特征，但是温度平流模拟的结果在量值上略大于实况。

Their center is the area of lowest atmospheric pressure, often known in mature tropical and subtropical cyclones as the eye.

其中心是该地区的最低气压，往往称为成熟的热带和亚热带气旋的眼睛。

The foundation of the Cyclone D4 is its sturdy double-deck chassis.

基础气旋的D4是其坚固的双层底盘。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
