查询词典 troposphere

The results showed that extremely cold rain and snow weather of Sichuan Basin was related well to the variations of water vapor、 frontogenetic function of Yangtze River Basin. at the mid-lower level of the troposphere, especially at 700 hPa level, there was water vapor convergence exiting lastly in Sichuan Basin for long time. And the time of convergence of water vapor was congruous with of cold air in Sichuan basin, and provided the water vapor conditions for the occurrence of low-temperature disaster.

结果表明：四川盆地的低温雨雪天气与南来的水汽变化及长江流域的锋生作用有密切关系，在对流层中低层700hPa上，四川盆地长时间存在稳定的水汽辐合区，水汽辐合的时段基本与盆地冷空气活动时间段一致，这为低温降水的发生提供了水汽条件。

This is because the top of the troposphere is normally very cold, causing ascending water vapour to freeze into ice crystals that drift and fall, rather than continuing up into the stratosphere.

这是因为对流层的顶端通常极其寒冷，上升的水蒸汽凝结成飘落而下的冰晶，而没有继续上升进入平流层。

Newell, et al ., found 10 huge filamentary structures that are the preferable pathways of water vapor movement in the troposphere (the lower 10-20 km of the atmosphere) with flow rates of about 165 million kilograms of water per second.

纽维尔，等人，发现10个巨大的丝状结构，是最好的途径，水汽运动在对流层（下10-20公里的大气层）与流率约1.65亿公斤水每秒。

The strong westerly jet in the upper troposphere is linked to the Mongolia cyclone and frontogenesis at low level which can cause strong wind and further provides the dynamic factor for the increased DWF in Beijing.

春季对流层高层的东亚西风急流增强能使低空的蒙古气旋加强和锋生，从而引起地面大风，为沙尘天气频次的增加提供动力条件。

At the same time, we discussed the fittable field of deep convective impressible model comparing with the origional pressible equations.The result is that deep convective impressible model is close to the pressible model and is good to be used to simulate troposphere.

本文首先对中小尺度动力学进行理论探讨，特别是与本文有关的深对流不可压动力学模型，比较它与原始可压运动方程组的联系及其适用范围，表明在对流层的研究中使用浅对流不可压模型是不可行的。

Isoprene is one kind of important NMHC, and also the most abundant volatile organic compound releases from vegetation in troposphere.

光化学烟雾和大气臭氧形成的重要前体物之一——非甲烷烃的排放受到研究者的热切关注。

The result shows that the severe convection weather arise in the transition from verticality to forward slant of the upper trough, so there was a different advection between the mid- and lower- troposphere, which was quite important to the formation and development of convective instability. The event was triggered by the surface low and meso-scale convergence line, and the squall line was direct influencing system.

结果表明：这次强对流天气过程发生在高空槽由垂直结构向前倾结构转变的过程中，中高层干冷平流、低层暖湿平流的大气层结增强了对流不稳定的发展，飑线是此次强对流天气的直接影响系统；太行山地形和平原南部的中尺度辐合线，对飑线系统的触发、组织、移动具有重要作用，强对流区发生在地面中尺度辐合线南侧的偏南气流里。

Great differences between them are found in amplitude, and attributed to the strong background wind in troposphere and steady weak wind in lower stratosphere. Steady diurnal variation of temperature appears above 23 km, and the same variation in pressure is found starting from lower altitude, which together suggest a weak diurnal variation in atmosphere density above 23 km, that approximates a constant at each height.

发现风场振幅的变化与统计平均的结果存在较大差异，这归结于当地冬季对流层内强烈变化而低平流层内相对稳定的风场；温度在23 km以上存在稳定的周日变化，气压在更大的范围内存在与温度类似的周日变化，这使得在23 km以上大气密度的周日变化十分微弱，在各个高度上近似为一个常数。

Meridional heat transfer by large-scale eddies is most significant in the upper troposphere of middle latitude.

大尺度湍涡的子午线热输送在纬度对流层上层是最重要的。

In this paper, four parts are included to study the role of cloud dynamics, microphysics and chemistry process in ozone photochemistry and sulfur chemistry in the troposphere.

本文分四部分研究了与云过程有关的云动力学、云微物理和化学过程对对流层大气臭氧光化学和硫化学的作用。

He is the most remarkable man that I have ever known.

他是我知道的人中最值得注意的人。

Increased appearance of lymphocele was noticed in patients with diabetic nephropathy, congenital malformations of the urinary tract, and inflammatory diseases, including glomerulopathy and extraglomerular ones, after high-voltage radiotherapy and after removal of the renal graft.

经过高压放射疗法和切除移植肾后，在糖尿病肾病患者、泌尿系统先天性畸形患者和炎症患者身上发现淋巴囊肿有所增加，包括肾小球病和球外疾病等。
