对流

With the sun rising, heat convection gradually to the ground, the clouds will gradually change, that is, to gradually approaching bad weather, local weather grew worse, it is a " alpenglow do not go out."

随着太阳升高，热力对流逐渐向平地发展，云层也会逐渐变密，坏天气将逐渐逼近，本地天气将愈见变坏，这就是"早霞不出门"的原因。

The computation of two-dimensional advection transport using current methods such as Alternating Direction Implicit Method and linear interpolation technique can be subject to numerical attenuation,parasite oscillation and poor reproduction of wave propagation when large time steps are used.

在概化的平面区域内，采用上述方法模拟了二维初始浓度高斯分布和水流激波在旋转速度场及均匀速度场上的对流输移问题，结果表明方法在优化幅值衰减和数值扰动以及计算效率方面具有相当的发展潜力和应用前景

It is found that in summer, the region between the southern edge of the westerlies and the northern margin in the subtropical anticyclone of the West Pacific is a favorable location for strong deep summer convection and MCS development.

夏季汛期降水主要受东亚夏季风的影响，非台风暴雨的出现与夏季风的进退一致。夏季在东亚西风带南缘和西太平洋副热带高压之间的地区，是夏季最有利于深对流和MCS发展的地区。

WT5BZ The operational numerical weather forecasting model T63 is employed to study the impacts of precipitation on the movement of the anticyclone over the Western Pacific.

The basic concept in these sections is replacing backward Euler's method by modified backward Eulers's method to approximate the characteristic differential equation and discretizing the convection-diffusion equation at the middle point of the approximate characteristic curve, which will make the convective term get up to second order accuracy.

这三节的基本离散方法是用改进的Euler公式代替向后Euler公式来近似特征微分方程，并且将近似特征线的中点作为离散节点，使得对流项的离散精度提高到二阶，对于扩散项，将其转移到待求时间层进行离散。

Then in the first chapter, the device is modeled to get approximate value of each parameter.

最后对流水中可能出现的器件失效机理进行分析，并提出改进方法。

In India, the flow is from the Arabian Sea and the Indian Ocean.

在印度，这样的区域空气对流来自阿拉伯海和印度洋。

The tests and studies on the rhyolite filtering material show that the functions of the rhyolite material are superior to that of the arenaceous quartz, and the rhyolite flitering material is worth further studying and developing.

对流纹岩滤料的初步试验研究表明，流纹岩滤料的性能明显优于石英砂，是比较理想的天然无机滤料，具有进一步研究开发价值。

We employ maximum principle argument to get an error of size O.

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
