急流

In DMMCS, there is an alternative distribution of inertial instability column and inertial stability column, at the west and south, there lie negative CVV columns, while negative CVV column is beneficial to deep moist convection.(4) The strong slantwise convection induced by inertial instability, baroclinic instability and conditional symmetry instability will enhance the upper level southerly component. Because of the appearance of the compensated downdraft at the low level of the south side of DMMCS, the low level southerly is intensified, the enhancement of upper- and low-level cores are in favor of the development of DMMCS. And that will do favor for the reinforcement and maintenance of inertial instability, baroclinic instability and conditional symmetry instability, it is a positive feedback process.

深湿对流系统中高层西侧为负MPV2 柱，东侧为正MPV2 柱；(3)深湿对流系统中惯性不稳定柱与惯性稳定柱相间分布，西侧为负CVV 柱，东侧为正CVV 柱，负CVV 柱对深湿对流起激发作用；（4）惯性不稳定、湿倾斜不稳定和条件不稳定产生强的倾斜式对流，而强的倾斜式上升运动加强了深对流系统北侧高层的南风分量，因深对流系统南侧低层出现补偿性下沉气流，因而低层南风加强，高低空急流中心的加强会进一步加强对流的发展，使得惯性不稳定、湿倾斜不稳定和条件不稳定增强和维持，这是一个正反馈过程。

在寺的东南，是人工瀑布，急流飞泻，水帘横出，令人心旷神怡。

Euripus:a sea channel characterized by turbulent and unpredictable currents.

"急流水道：潮流或海流急剧进退，无法预知的水道。"

On the banks were men fishing. One of them fell into the swift current, rolled over and sank to the bottom of a deep hole.

However, if there is no way but only the wisdom, as will be driving, navigable, they themselves can control the reins can show off too, such as strings, can Quant shake like wind, racing along a flat plain or a pier, as if in their own palm of your hand, but an experience to narrow the Taihang Mountains, rapids rapids of the storms, will do nothing to screaming in pain, these people do not capsize, do not overturn the really very small.

但如果没有方法而只有智慧，就像会驾车、行船的人，自己炫耀能把缰绳控得如弦，能把船浆摇得像风，驰骋在平坦的原野或者码头上，好像在自己的手掌上，但一遇到太行山的羊肠小道、急流险滩的大风大浪，都会束手无策地呼天抢地，这些人不倾覆、不翻车的实在太少了。

The strong westerly jet in the upper troposphere is linked to the Mongolia cyclone and frontogenesis at low level which can cause strong wind and further provides the dynamic factor for the increased DWF in Beijing.

春季对流层高层的东亚西风急流增强能使低空的蒙古气旋加强和锋生，从而引起地面大风，为沙尘天气频次的增加提供动力条件。

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。
