查询词典 tropopause

Year global analysis of characteristics of tropopause distribution and variation.

40年全球对流层顶分布和变化特征分析。

The results are as follows:① The mean spatial position of the tropical tropopause and the polar tropopause approximately consistent with heating fields of the tropopause, and isopiestic, isotherm present zonality and appear wave motion at the middle and high latitude . The tropopause temperature and pressure are not symmetrical between two hemispheres.② The interannual variations of the tropopause zonal-mean pressure and temperature anomalies are remarkable.

结果表明：①热带对流层顶和极地对流层顶的平均气压场的空间位置和热状况大致吻合，并存在空间波动性，两半球对流层顶的温压场具有显著的非对称性；②对流层顶的纬向气压与温度距平场都具有不同尺度的年际和年代际变化，两极地区对流层顶的温压场最不稳定，两半球中纬度地区的时间演变尺度存在明显差异。

It is also shown that one of the most important reasons of the heavy rain amplification is the cold air which spreads to south from midlatitude in the lower troposphere and transports into the typhoon low pressure. The study of PV on isentropic surface shows the active state of the midlatitude cold air. The tropopause folding, which means that high PV spreads downward from the upper troposphere or stratosphere, helps the releasing of potential instability energy and the development of rainstorm.

分析表明：对流层低层中高纬度冷空气扩散南下在台风低压环流区附近的"侵入"作用是此次特大暴雨过程的最重要的原因之一；等熵面位涡的分析进一步说明了中高纬地区冷空气的活动状况；对流层高层或平流层低层高位涡的下传有利于位势不稳定能量的释放，使得暴雨增幅。

According to model trial results, it was found that the tropopause was not a simple mass surface.

STE对对流层顶选择的敏感试验表明，对流层顶不应该选择为一个简单的物质面，而应表现为一个过渡区。

Stratosphere are from the tropopause up to about 50 kilometers between the regions.

平流层是从对流层顶向上至约50公里之间的区域。

In the northern high latitudes the tropopause height is maximum during summer and winter.

在南半球的高纬地区和北半球的热带地区是冬高夏低；而在北半球的高纬地区在冬季和夏季有两个锋值存在。

As soon as the tropopause is reached, temperature stops decreasing with height.

一达到对流层，温度就停止随高度上升。

Model results show that the annual cycle of the tropopause height has remarkable impact on the distribution of ozone. The local change of ozone can be more than 10％.

1模式结果表明对流层顶高度的季节变化对上对流层和下平流层臭氧的分布有明显的影响，臭氧的局地变化可以超过10％。

Spatial distribution of the tropopause height: The strongest meridional gradients in the tropopause height are between 20°and 40°over both hemisphere.

1对流层顶高度的空间分布特征：在两半球的纬度20°到40°之间对流层顶高度的经向梯度最大。

The Tibetan tropopause is obviously different from the other regions at the same latitudes, c.a. 0.7 km higher in average, and the seasonal height variation of tropopause over Tibet is distinguished, in amplitude and phase, over the corresponding latitudes.

青藏高原上空对流层顶与同纬度其它地区间存在较大差异，该地区对流层顶比同纬度其它地区高约0.7 km，流层顶高度的季节变化与同纬度其它地区也明显不同，表现为振幅远大于同纬度其它地区，位相也明显不同。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
