急流的

But they moved slowly,and all the time the river was carrying them towards the place where the water crashed twenty metres down onto rocks.

但是他们游的很慢，河水始终冲着他们向一个急流漂去，那个急流从20米高的地方掉到下面的岩石上去。

Both theory and practice analysis illustrate that stronger divergence field results from uneven distributed horizontal wind field on the right when high level current axis slopes. Owing to convectional wind convergence at low level responds to high level divergence and leads to storm.

理论和实际分析均表明：高空急流轴一旦发生倾斜，则由于其出口区水平风场的分布不均匀势必会在倾斜急流轴出口区的右侧产生较强的辐散场，由于对流风的作用，低层辐合必然会对高层辐散产生响应，诱发暴雨发生。

Analysis and a numerical simulation study are carried out to investigate the effects of surface fluxes on the development of a long-lived severe squall line that occurred on 12 July 2004 near Shanghai using the RSM-RANAL re-analysis data and WRF model.

使用水平分辨率20km的RSM-RANAL再分析资料和WRF模式，对2004年7月12日影响上海地区的一次飑线过程进行分析和数值模拟，结果表明：(1)雷暴发生区域的西北侧约300km处有一冷锋，地面风场辐合；中低层为一致西南急流，雷暴发生区域上空300h Pa位于西风急流右后侧辐散区中；地面存在明显的温度梯度。

The analysis shows that the snowstorm occured under the large scale circulation background of two-trough-two-ridge over the Eurosian continent, and resulted from the coupling of the upper level westerly jet and the low level southwesterly jet.

研究表明：这次暴雪发生在两槽两脊的大尺度环流背景下，是高空西风急流和低空西南风急流上下耦合作用的结果。

It shows that the typhoon depression lasted for five days on land was because of a strong and wide convergence zone between two high pressures,together with the strengthening of southwesterly jet and its movement direction determined by the maximum wind speed by the subtropical high and the southwesterly.

其结果表明：两高间强而宽广的辐合带和西南急流增强使台风低压在陆上连续5d不消，副高、西南急流在低压区形成的最大风速中心位置决定台风低压移动方向。

Had the Stern of the Ship been fix'd, and the Forepart broken off, I am perswaded I might have made a good Voyage; for by what I found in these two Chests, I had room to suppose, the Ship had a great deal of Wealth on board; and if I may guess by the Course she steer'd, she must have been bound from the Buenos Ayres, or the Rio de la Plata, in the South Part of America, beyond the Brasils, to the Havana, in the Gulph of Mexico, and so perhaps to Spain: She had no doubt a great Treasure in her; but of no use at that time to any body; and what became of the rest of her People, I then knew not.

经过观察，我大受鼓舞，决定第二天早晨乘第一次潮汐出发。我把水手值夜的大衣盖在身上，在独木舟里过了一夜。第二天一早，我就驾舟出发了。最初，我一出海就朝正北驶去，走没多远，就进入了那股向东流动的急流；小舟在急流中向前飞驶，可是流速没有上回岛南边那股急流那么大，所以我尚能掌握住小舟。我以桨代舵，使劲掌握航向，朝那失事的大船飞驶过去。不到两小时，我就到了破船跟前。

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。

The rapids of a river that runs between the steep precipices of a gorge or narrow valley.

急流河流的急流，奔流在山峡或狭窄山谷的悬崖峭壁之间

Just as I had set my Mast and Sail, and the Boat began to stretch away, I saw even by the Clearness of the Water, some Alteration of the Current was near; for where the Current was so strong, the Water was foul; but perceiving the Water clear, I found the Current abate, and presently I found to the East, at about half a Mile, a Breach of the Sea upon some Rocks; these Rocks I found caus'd the Current to part again, and as the main Stress of it ran away more Southerly, leaving the Rocks to the North-East; so the other return'd by the Repulse of the Rocks, and made a strong Eddy, which run back again to the North-West, with a very sharp Stream.

我刚竖起桅杆张好帜，船就开始向前行驶了。我发现四周水色较清，知道那股急流在附近改变了方向。因为，水急水则浊，水缓水则清，我知道那股急流在这儿已成了强弩之末了。不久我果然发现，在半海里以外，海水打在一些礁石上，浪花四溅。那些礁石把这股急流分成两股，主要的一股继续流向南方，另一股被礁石挡回，形成一股强烈的回流，向西北流回来，水流湍急。

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。
