环流的

The past decade has been a rapid expansion of our empirical knowledge of the observed circulation anomalies.

过去的 10 年曾是关于观测获得的环流异常现象的经验知识的大丰收的 10 年。

Utilizing the latitudinal mean ot upper meridional wind of 1950 given by Buch and Starr and White, mean meridional circulation has been studied.

本文利用了Buch和Starr与White所计算的1950年各纬度上空的平均经向风速，绘制了子午面上的平均环流(全年：图1，冬季：图2，夏季：图3)，图中显示出三个环型，低纬度和高纬度的两个正环型与中纬度的逆环型。

But, the technology with circumfluent higher suffocating asks, complex operating sequence, longer operation time, make the application of this technology has certain limitation.

但是，环流熏蒸较高的技术要求，复杂的操作程序，较长的操作时间，使得这项技术的应用有一定的局限性。

The evolution of frontal rainbands happening during the frontogenesis induced by deformation field is investigated through the numerical cloud model. Besides, in order to get insight from the results of numerical simulations, the semigeostrophic frontogenesis model is used to investigate the effect of diabatic heating on the frontogenesis and the analytical method of WKBJ is used to study the influence of large-scale deformation field and frontal circulation on the development of symmetric disturbance happened in the frontal zone.

为了加深对数值模拟结果的理解，还利用半地转模式对非绝热加热影响锋生的过程进行了讨论，通过WKBJ方法讨论了变形场锋生条件下对称扰动的发展，从中可以了解大尺度变形场和锋生环流对中尺度扰动的作用，这方面的工作可以对前面非静力数值模拟结果的理解提供帮助。

As the application of the intermediate models is concerned, the works applying the intermediate models to investigate the topographic boundary layer, frontogenesis and low-level frontal structures, and the boundary layer jet are summarized in this article. It is mainly focused on the dynamic characteristics of the Ekman layer and its effect on the low-level structure and circulation of the weather systems illustrated by the models. It is shown that the intermediate boundary-layer models have great potential in illustrating the low level structures of the weather and climate systems as they are coupled with the free atmospheric models.

对于这些Ekman边界层近似理论模型的进一步应用问题，主要回顾和总结了利用上述模型探讨地形边界层结构、大气锋生过程、低层锋面结构和环流以及边界层日变化、低空急流形成等动力学问题的研究，并对这些研究所揭示的Ekman层动力学特征及其对自由大气低层运动的影响进行了分析，结果表明，这些Ekman边界层近似模型可以较好地揭示大气边界层动力学特征，在大气边界层动力学及其与自由大气相互作用的研究上具有重要价值。

The structures of temperature and salinity, the formation mechanism of the well-mixed warm water column in the central Bohai Sea and the corresponding current field are the important topics in the physical oceanography in this area.

其中温、盐度场的空间分布结构、渤海中部夏季较高温度水体的形成机制及相应的环流场是值得研究的课题之一。

Suspended right in the center of the apartment, leaving untouched the floor and the circulations around, it divides the space, reversing the perception of the atmosphere in the apartment by making private what is usually not : the living room.

暂停权利在公寓的中心，让触及地面和周围的环流，它划分的空间，扭转了使私人公寓通常没有什么：客厅大气的感觉。

Attention has been paid greatly to the research on mesoscale circulations of atmosphere and pollutant transport i...

近年来随着沿岸经济的快速增长和污染问题的日益加剧，对沿岸区域大气中尺度环流及大气物质输运的的研究越来越受到重视。

By analyzing next-spring abnormal features of 500 hPa height and 850 hPa, 200 hPa meridional wind due to Nino3 SST rising, it is found that Nino3 SST rising abnormally in the second half year leads to 500 hPa height field rising in the tropic and Northwest Pacific subtropical region, namely the Northwest Pacific subtropical high is stronger and shifts westwards and northwards compared with the mean, and the trough over East Asia is weaker with its location shifts eastwards; the height field falls from the area around Balkhash to Baikal Lake, i.

通过分析下半年Nino3区(150o~90oW，5oS～5oN)海表温度升高引起的次年春季500 hPa高度、850 hPa及200 hPa经向风的异常特征，发现下半年Nino3区显著升温，可导致次年春季热带和西北太平洋副热带地区的500 hPa高度场升高，即西太平洋副热带高压偏强、偏西、偏北，东亚大槽偏弱、偏东；巴尔喀什湖至贝加尔湖的高度场降低，即该地区经常有低槽维持；亚洲至西太平洋地区盛行纬向环流。

These experimental results indicate that the improved plug-in repeative control scheme combining with the circumfluence R.M.S. compensation method are feasible for inverts parallel operation,which will meet the demand of power single-phase invert-paralleling systems.

实验结果表明，对于单相逆变器并联系统，本文提出的改进型嵌入式重复控制策略以及基于环流有效值的均流补偿策略是可行的，可以满足大功率单相逆变器并联的要求。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
