查询词典 plateau

The roughness shape of ceramic machining surface is analysed by four kinds of test methods: surface profile, scanning electron microanalyses, bearing ratio curve and profile ratio of peak to valley. Ceramics are machined by"plateau honing"to obtain the plateau property and wearability of machining surface. The machining surfaces own its functional surface.

Anomalous anticyclone at the upper level is form in response to the enhanced convective heating off the equator, resulting in increased geopotential height and temperature over the Tibetan Plateau and in favor of the early BOB seasonal transition. Another effect of Positive SST anomalies over the Warm Pool is to induce anomalously strong zonal monsoon circulation. The anomalous zonal monsoon circulation strengths the southerlies in upper levels due to Coriolis force. Thus the enhanced warm meridional advection in connection with the warming over the Tibetan Plateau lead to early seasonal transition over the BOB region.

高空大气通过热力适应过程对这种异常对流加热的响应是产生异常反气旋环流，则高原上空的位势高度偏高，温度偏高，引起季节转换偏早；暖池海温异常偏高的另一作用是，它激发出异常强的季风纬向环流，在高层，季风纬向环流受到柯氏力作用又使得南风加强，导致孟加拉湾东部地区经向暖平流及其北部下沉增温加强，加速了孟加拉湾季节转换进程。

The southwest vortex restricted the development of the plateau vortex in some way at the early stage when it appeared in the lower atmosphere. When they were coupled longitudinally, the vertical difference caused by the different vorticity advections between the upper and lower levels excitated the updrafts under 500 hPa and strengthened cyclone vorticity, and then the positive vorticity at 500 hPa and 700 hPa increased by two times The change rate of positive vorticity facilitated the plateau vortex to move eastward.

分析表明：高原涡与西南涡涡心之间的纬向距离在5个纬度的时候，两者上升气流都在500 hPa以下，当两者继续东移，在经向上耦合的时候，二者同时得到发展，西南涡中心的上升气流达到300 hPa，而高原涡中心的上升气流突破200 hPa；西南涡在低层出现初期，在一定程度上制约了高原涡的发展，随着两者在经向方向发生耦合，上下涡度平流不同造成垂直差动，将激发500 hPa以下的上升运动与气旋性涡度加强，使得500 hPa与700 hPa涡心正涡度值的增大近 1倍。

It is found through analysis of the shear line over Qingzang Plateau from May to August in 1979 by the use of scientific experimental data that the plateau shear line can be generated respectively in the easterlies, in the westerlies and in the neighourhood of the zero line between easterlies and westerlies.

切变线；无风带；西风带；毫巴；东风带；大尺度环流；本文利用科实资料对1979年5—8月青藏高原切变线进行分析后发现：高原切变线可以分别在东西风带分界的零线附近、西风带中和东风带中产生。

The weather of Yunnan-Guizhou Plateau is greatly impacted by the emergence of the Ferrel cell, which is resulted from the lifting effect of Tibetan Plateau and the southward anomaly of the Hadley cell.

青藏高原的抬升作用与Hadley环流偏南导致Ferrel环流的生成、加强对云贵高原的天气有重大的影响。
