- The vertical vorticity transition is not favorable to the strengthening of plateau vortex in the middle and low troposphere levels. 垂直涡度输送不利于对流层中低层低涡加强。
- In the years with zonal wind anomalies, the circulation of high and low troposphere and the vertical motions in the troposphere have significant characteristics. 高低层纬向风异常年，对流层上、下部环流和对流层中垂直运动有显著的特征。
- The main impact system is cold trough on 500hPa, low eddy shear line on 700hPa, lower troposphere jet in the southwest and surface occluded front. 其主要影响系统是500hPa冷槽、700hPa低涡切变线、西南低空急流以及地面"锢囚锋"。
- H2O absorption is predominant in the troposphere, particularly the lower troposphere. H2O吸收在对流层，特别在对流层下部起着主要作用。
- Ozone enhancement was observed in the lower troposphere over Kunming on 21 March 2001 using electrochemical concentration cell ozonesondes. 摘要2001-03-21在昆明用电化学臭氧探空仪探测到了对流层低层异常的高浓度臭氧分布。
- A new gale center is generated near the lower troposphere of westerly belt system when it has partly invaded into the egion of typhoon. 发现在侵入台风后的西风带系统附近的低层产生一新的大风中心,在该中心的下风处的低层辐合区产生暴雨。
- Two wind maxima with jet-stream characteristics often occur, one above the other, in the lower troposphere by the south side of therainstorm area over South China in summer. 华南暴雨区南侧对流层中下层常常同时存在两个大风层且各具急流的特征。
- zonal wind anomalies in high and low troposphere 高低层纬向风异常
- During the heavy rainfall in the upper troposphere the strong DPV and MPV tend downwards to the low-level, and vice MPV in the lower troposphere stretch up. 强降水发生期间，中高层强干湿位涡向低层传送，低层负湿位涡向上伸展。
- Scientists think this haze, which is created by power stations and cooking-fires, may be radiating heat into the lower troposphere, at altitudes in which glaciers are found. 科学家们认为，该烟雾产生于发电厂与烹饪用火，可能将热量辐射至较低的对流层中，这一海拔正是冰川之所在。
- TOMS AI images and the atmospheric background circulations suggest that biomass burning plumes in South Asia are transported to Kunming and cause the enhancement of ozone concentrations in the lower troposphere. 这与以往研究中东南亚地区生物体燃烧导致华南地区对流层低层臭氧浓度异常增高有所不同。
- In the development of the vortex, there exist three branches of air flows in the upper and lower troposphere, which are compared with those in the heavy rain region onthe east side of Rocky Mountains. 在涡发展时期;对流层高低层存在“三支气流”;并将其与美国落基山东侧暴雨区内的“三支气流”作了比较.
- The result indicates that the model successfully simulates the monsoon system in the lower troposphere including the classic tropical monsoon,the subtropical monsoon and the temperate-frigid monsoon. 结果表明，模式成功模拟出对流层低层的季风系统，包括经典的热季风以及副热带季风和温寒带季风。
- For the warm-type, clouds also extended into the prefrontal area because of more humid and warmer southerlies as well as stronger convergence and upward motion in the lower troposphere. 两类锋面之云区均主要分布在锋上与锋后，唯暖型上滑锋锋前仍有些许云量，此应与锋前近地层南风分量带来较暖湿空气，且锋前有较大之低层辐合与较大之上升运动有关。
- Therefore, it is not the advection process, but the vertical heating profile, which causes the atmospheric response in the lower troposphere out of phase with that in the upper troposphere. 因而阐明，不是由于平流作用，而是由于加热垂直梯度方向的改变，在加热中心下方产生正涡度强迫，中心上方产生负涡度强迫。
- The US coin of the lowest denomination is the cent. 美国硬币的最小单位是美分。
- The government is trying to keep a low profile on this issue. 政府力图在这个问题上保持低姿态。
