查询词典 meridionally

将东亚纬向海平面气压差与低纬度高低层纬向风切变结合，定义了一个能表征东西和南北向海陆热力差异的东亚季风指数。

Obtained are a few typical patterns of wind change versus height in the boundary layerthrough analysis of 1987 profile s and meridionally and zonally mean vertical circulation cells fordifferent levels from surface up to 3000 m.

通过分析1987年我国各测站低空（3000m以下）各层次风随高度分布廓线和各经、纬度平均垂直环流，得出边界层内风随高度变化的几种典型分布以及在108E以东我国边界层内存在一对经向反、正垂直环流圈。

Based on the review of the description of subtropical high and the research on its formation, fluctuation characteristics and physical mechanisms, it is found that the subtropical high is refered to the area where pressure is relatively larger. Its formation is due to the existence of mean meridional circulation that accumulates air mass to subtropical areas. The subtropical high is belt-like with meridionally non-uniform feature and this is a zonal mean point of view.

通过对副高的描述、形成及演变特征和物理机理的研究进行回顾，认为：副高是相对的气压的高值，是由于平均经圈环流的存在，使得有空气质量在副热带地区的堆积而形成的，成为带状，表现出在经度方向的不均匀，这是一种纬向平均的观点；同时，在这个平均的高压带上常常有闭合的单体存在，表现出纬向的不均匀。

Based on the 1950-1998 SST and NCEP/NCAR reanalysis data, the temporal/spatial variations of SSTA in the Western Pacific Warm Pool region have been analyzed in this paper by means of the methods of EOF and composite analysis. Results show that there are two main spatial patterns of the WP SSTA: one is uniform in the whole region, the other is meridionally anti-symmetric.

采用海温资料和NCEP/NCAR 49a再分析的高度场、风场资料，利用EOF、合成分析方法，研究了夏季暖池SSTA的时空演变，结果显示：夏季暖池SSTA具有整体一致性分布和南北区域的反对称分布两种空间分布型。

At eccentricities of 20 degree, VEP yielded the largest responses to gratings perpendicular to the visual field meridians through stimulus locus and the lowest responses to meridionally oriented gratings.

在距中央凹20°视角同心圆的八个刺激位置上，VEP反应幅度对与向心线垂直方位的光栅刺激，有统计意义上的优势。

The meridionally accelerated axial-flow fans including meridian acceleration rotor, vaneless diffuser and volute was numerically simulated in the whole flow passage by Reynolds time-averaged N-S equations with tensor and k-ε turbulence model.

采用三维雷诺时均N-S方程和标准k-ε湍流模型，对包含叶轮、无叶扩压器与轴向蜗壳于一体的子午加速风机进行了整机全流道的数值模拟。

When the spatial pattern is meridionally anti-symmetric, in the north-warm/south-cold years, an anticyclonic anomaly circulation exists over the warm pool at 850hPa, the easterly near 15°N and the westerly near the equator are greatly strengthened, while the center of the 200 hPa anticyclonic circulation moves to the East Asia, and the Hadley circulation is affected evidently, so the summer rainfall may be above normal in the middle and lower reaches of the Yangtze River, and vice versa.

当SSTA为南北反对称分布时，北暖南冷年850hPa暖池区上空为一反气旋偏差环流，15°N附近东风气流和赤道附近西风气流增强，200hPa反气旋偏差环流中心移到东亚大陆上空，长江中下游地区为上升气流，降水明显增多，华北地区为下沉气流，降水减少；冷异常年则相反。

The possible mechanism through which the winter AO influences winter air temperature in northeast China is that at the ground surface when the winter AO index is in a low phase,the Siberia high is strengthened,the winter monsoon over the East Asia is also strengthened,and northeast China undergoes a successive cold winter;and in the middle troposphere,when the winter AO is in its low phase,the East Asia trough is strengthened,the ridge west and north of Baikal Lake is also strengthened,the circulation develops meridionally,the northerly wind is strengthened,and northeast China undergoes successive coldwinter.

可能影响机制是：在地面，冬季北极涛动处于低指数期时，西伯利亚高压增强，亚洲大陆偏北冬季风增强，东北为持续冷冬期；在对流层中层，冬季北极涛动处于低指数期时，东亚大槽加深，贝加尔湖以西以北脊增强，环流呈经向型发展，东北对流层中层偏北风增强，东北为持续冷冬期。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
