西风

The midlatitude Asian continent can be roughly divided into two distinct climatic regions: the humid easternsouthern part of Asia mainly controlled by monsoon circulation and inland arid Asia (including the coldarid northern Tibetan Plateau) in the western part dominated by the midlatitude westerlies.

中纬度亚洲地区存在主要受季风环流影响的东南部湿润地区和主要受西风环流控制的内陆干旱区(包括青藏高原北部高寒干旱区，简称西风区)。

The westerly has blowd every night,from the Mountain Valley Zhenyuan to Sand River,pine recite bamboo rhyme,valley song mountain cry,at the old time strange westerly is called "nine wells westerly".

西风每夜从此起，自山谷真源至沙河、松吟竹韵、谷应山鸣，古时候把这股奇怪的西风称为《九井西风》。

The circulation features in the westerlies, especially, distribution and variation of the upper–level westerlies play an important role in controlling the different tracks.

西风环流，尤其是中、高纬度高层西风的分布及其变化对于形成不同类型的台风路径亦起了很重要的作用。

The forecasting of turning typhoon is a difficulty, In this paper, the circulations of six turnning typhoons and their relationship with westerly in 2008 are analysed to get the conclusions below: weather typhoon would turn or not is in close relation to westerly when it betweens continenta1 high and West Pacific subtropical high?

分析了2008年6个东北转向台风的环流形势及其与西风槽等的关系，得出当台风处于大陆高压和西太平洋副热带高压之间的中纬度西风槽前时，其转向与西风槽密切相关的结论。

In China, the west is nipping bise, often reminiscent of dongfeng floating down, a British idea of the west, warm, heralds spring's arrival, will make the earth, but in the spring wind is bone-chilling English culture Middle East wind.

在中国，西风是刺骨的寒风，经常使人联想起离愁别绪，东风则像是英国人心目中的西风，温暖，预示着春天的到来，会使大地春意盎然，而在英语文化中东风才是刺骨寒风。

Also the seasonal variation of mean gedstrophic westerly, and the distribution of extra-long wave at this layer were analyzed.

分析了南半球对流层500hPa平均地转西风随纬度的分布特点，平均地转西风季节变化特点，计算分析了南半球位势高度对纬向平均的偏差，分析了超长波的分布特征。

On the contrary, the opposite pattern occurs when the AACEF is stronger.(3) On interannual timescale, the changes in the SH Ferrel cell lead to the anti-phase variation of the subtropical high and the circumpolar low, i. e., the Antarctic oscillation .

研究发现，当夏季南极涛动偏强时，南极极涡和高纬度的西风急流强度都偏强，但中低纬度西风急流的强度偏弱；反之，当南极涛动偏弱时，南极极涡和高纬度西风急流强度将偏弱，中低纬度西风急流强度将偏强。

Along 90°E the easterly wind in mid-upper layer is obviously weakened to the south of the plateau, and the westerly wind in mid-upper layer along 140°E is enhanced to the south of 35°N but it is obviously weakened to the north of 35°N.

利用p-σ九层区域气候模式进行高原隆升对东亚副热带西风急流影响的敏感性试验，分析高原隆升过程中西风急流垂直结构和水平结构的变化，并对其变化的原因进行初步分析。

As a result, a weak indirect cell is formed in high latitudes. By the 36th time step, the model atmosphere accomplishes the transition form one-cell circulation to two-cell circulation. There is a momentum source in the upper subtropical region. During the transition, the"polar westerlies jet"gets weakened and vanishes at the end, while the subtropical westerlies jet gets strengthened. At this two-cell stage, the generation and dissipation of westerly angular momentum do not balance each other, and the atmosphere is still at an unstable state with great surplus of angular momentum generation.

随着模式的运行，直接环流加强，地表东风带制造西风角动量加大，上支气流的加强，同样在科氏力的作用下，在副热带地区形成副热带西风急流，同时所谓的&极地西风激流&向赤道靠拢、减弱，最后消失，这时在整个半球形成了靠赤道的直接环流和靠极地一侧的间接环流，两圈环流形成的过程仅仅需要9个小时左右。

The further composite analysis suggests that in the positive first mode SST anomalies years, the main body of the Aleutian low in winter season shifts southwestwards, then, the positive atmospheric temperature anomalies at the lower level and negative westerly wind anomalies at the upper level occur in northeast Asia to the west coast of North American.

进一步的合成分析表明，在第1种耦合型SST正异常年里，冬季阿留申低压主体位置偏西南，从东北亚到北美西海岸的西北-东南向带状区域内是低层大气温度正异常区和高层西风负异常区，西风负异常中心位于西风急流出口处的北太平洋中东部，而西风急流主体区的风速变化很小。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
