高层大气

The vivid green and purple auroral colors are caused by high atmospheric oxygen and hydrogen reacting to a burst of incoming electrons .

那鲜艳的绿色和紫色是由飞速而来的带电粒子轰击着高层大气中的氧气和氢气而生成的。

By using data of Nobeyama radio heliograph, we calculate value of magnetic field in lower corona in some active region from thermal bremsstrahlung, and preliminary result has been obtained.

利用Nobeyama射电日像仪的观测资料，以热轫致辐射机制为基础对一些活动区的高层大气磁场进行了估算，得到了一些初步的结果。

Enceladus is 499 kilometers (310 miles) wide.

由于土星高层大气分子对太阳光的散射，，土星本身在紫外线波段并没有什么明显的特征。

该中心在空间等离子体、高层大气和天体物理方面的研究被国际公认为极为优秀的研究中心。

The atomic oxygen perpendicular distribution of the middle and upper atmosphere (100~500km) is simulated quickly and effectively based on the hydrostatics and mathematics software. The simulation results are compared with the data from MSISE-90 model, and they are coincident in order with certain difference in values.

基于修正后的流体静力理论和数学软件，对中高层大气100~500km 高度范围内氧原子的垂直分布进行了快速有效的模拟，将模拟结果与MSISE-90 模型提供的数据作了比较，二者数量级相等、仅数值有一定偏差。

At 40 North and southwesterly, upper atmosphere 'jet stream' winds occur.

在南北纬40°地区的高层大气中，发生从西而来的"急流"风。

It aims to understand and model the dynamical, chemical and radiative processes and their interactions in the upper atmosphere.

中高层大气研究的目的是要深入了解其中发生的主要过程及其耦合，并发展各种模式。

Northern China, parts of the US, the Sahel in Africa, the Middle East and Australia are all prone to severe dust storms which routinely travel thousands of miles and on occasion have been found to travel twice round the world in the upper atmosphere.

中国北方、美国部分地区、非洲撒哈拉南部地区和澳洲都面临着严重沙尘暴威胁。这些沙尘暴会有规律性的移动数千公里，其中更有甚者在高层大气中环绕地球两周。

Even though noctilucent clouds were sometimes seen in the past., all this extra methane carries more water vapor into the upper atmosphere, where it condenses at much higher altitudes to form more clouds that the sun's rays still strike long after sunset has brought the beginning of night to the surface far beneath them.

虽说过去天空偶尔也出现过夜光云团，但大气层中所含的那些过量的甲烷会将更多的水蒸气带到高层大气中；水蒸气在更高处凝结，会形成更厚的云层，夜幕降临以后很久，这些位于高空的云层下方还在受着太阳光的照射。

In section one, by using FICE scheme and TIME-GCM, a model of trace gases and OH airglow affected by gravity wave is set up, then the propagation of nonlinear gravity wave and the effect on trace gases and OH airglow are analyzed. The result shows gravity wave excited by tropospause forcing can propagate stably to the mesosphere through the stratosphere so that energy and momentum can be transferred from one region to another. In this process, gravity wave undergoes growth, overturning, convection and breaking. And the no-isothermal structure can accelerate the breaking of gravity wave in mesospause, and the breaking of gravity wave is an important source of convection and small-scale waves. The propagation of gravity wave will affect the distribution of minor species.

在第一部分的工作中，利用全隐欧拉格式和全球热层-电离层-中间层-电动力学环流耦合模式，对重力波的非线性传播及其在传播过程中对中高层大气中氧族和氢族成分和与之密切相关的OH气辉辐射的影响进行了数值模拟，结果表明，从对流层向上传播的重力波经历了产生、发展、饱和、对流产生直至破碎的非线性演化，大气的非等温结构加速了重力波在中层顶区的破碎，重力波的非线性传播是小尺度对流和湍流产生的一个重要的源。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
