环流的

In normal years, the onset time of summer monsoon over the SCS is approximately in the fourth pentad of May.

通过对各种指标确定夏季风爆发时间一致年份的大气环流特征分析表明，延伸到南海北岸附近地区的海上锋区对流加热和孟加拉湾北部陆地上的对流加热、沿东亚近海向西太平洋推进的冷空气是控制南海夏季风爆发的主要因素。

Numerical simulation results show that the typical features of primary flow, secondary flow and velocity redistribution in natural river bends are closely related to the special planform and flow depth conditions of natural river meanders. The lateral redistribution of flow is significant when water depth is small. The main stream approaches the concave bank upstream the bend vertex when river width is small.

数值试验结果表明，自然河流河弯中的主流、二次环流和流速重分布特征是与自然河弯的特殊几何形态特征、水深条件紧密相连的，水深越小则流速沿横向的重分布越为显著；河宽越小则水流动力轴线在凹岸的顶冲点越为提前。

The pressure ridge partly moved to southeast, it led to the cold air stream more moved to southeast, and the strong cold wave broke out. The water vapor from Caspian sea to Bslkhash lake accumulated at the upper of north Xinjiang, and it provided the water vapor condition for the cold wave. The ECMWF numerical forecast product accurately predicted the evolution trend of circulation (the position, intensity, path and speed of ground surface cold high pressure) of height field in this cold wave process. The predicted temperature at 850 hPa had good corresponding relation with the actual lowest temperature.

高压脊部分东南垮，导致强冷空气大举东南下，强寒潮天气暴发；里海到巴尔喀什湖的水汽在北疆上空聚积，为这次寒潮天气提供了水汽条件；ECMWF数值预报产品在这次强寒潮天气过程中准确的预报了高度场的环流场演变趋势，地面冷高压的位置、强度、路径和移速；850 hPa格点温度预报值与最低温度实况值具有很好的对应关系。

The results showed that two different nature of the fog (radiation fog and advective fog) have their common features. They are both formed in the zonal circulation.The abundant water vapor and thermal conditions are supplied by the southeast wind in the middle boundary layer. However, there are obvious difference between them .

结果表明：两种性质不同的大雾有其共同的特征，都产生于纬向环流下；中层的东南暖湿气流为大雾的形成提供了充沛的水汽和热力条件。

With the deeping of the trough and the westward moving of the tropical cyclone, the low level vortex and wind shear line extended along a southwest - northeast orientation over the Yangtze River. On the effect of high, middle and low latitude systems, a rainband in southwest - northeast orientation formed gradually.

随着阻塞形势的发展和热带气旋的西移北上，经向环流加强，主要影响天气系统——低空的低涡切变线沿西南－东北方向伸展，在高、中、低纬度天气系统的共同作用下，一条西南－东北走向的雨带逐渐形成。

The climatological mean and seasonal variability of the current systems are well inverted, especially the Tsushima Warm Current and its bifurcation, the East Korean Warm Current, the Japan nearshore branch, the confluence of the EKWC, and the North Korean Cold Current near the Korean coast and flows northeastward along the subpolar front, and a mesoscale anticyclonic eddy in the Ulleng/Tsushima Basin.

日本海的环流系统的季节变化都作了较好的模拟，特别是对马暖流和它的分叉、东朝鲜暖流，日本近岸分支、东朝鲜暖流汇流、朝鲜半岛沿岸的本朝鲜寒流、以及一个Tsushima海盆中尺度顺时针涡旋。

Through analysis of the 1999/2000 background field of winter circumfluence, we find that the changes of West Pacific subtropic high and polar vortex are important factors that affect the changes of winter climates characters of our countrys and decay or melt of sea ice in the Bohai Sea .

通过对1999／2000年冬季环流背景资料的分析，发现西太平洋副热带高压和极涡的变化是影响我国冬季天气气候特征变化和渤海海冰生消的重要因素，而副热带高压和极涡等大气活动中心的变化又与赤道东太平洋的厄尔尼诺现象及拉尼娜现象有关。

From 1997 to 1999,Gregory scheme succeeds in simulating the basic character of summer rainfall in china, i.e., there are drought in HuaBei and most north province of china in 1997 summer, a heavy flood in Yangtse River valley in 1998 summer and waterlog in south and drought in north of china.

改进后的Gregory方案不仅模拟出了中高纬环流形势的演变过程、西太平洋副高的强弱变化，包括副高的进退和北跳；而且模拟出了98年夏季我国长江流域的大范围降水。

The equatorward movement of a middle latitude trough-front system into the South China may give rise to the retreating eastward of the subtropical high ridge over the South China Sea.

1994年南海夏季风建立于5月第一候，利用MM5成功地模拟了这一过程，并通过敏感性试验，讨论了中纬度系统和中南半岛及其附近地区的积云对流对夏季风环流建立的影响，结果表明：（1）南下接近副热带一定强度的中纬度槽－锋系统的强迫，可引起南海地区副热带高压脊的减弱东撤。

Antarctic ice sheet is developing in cold enviromental condition for its high latitude condition. its is contral by katabatic wind.

南极冰盖是其高纬度的位置来获得良好的冷储条件的，冰盖表面主要受全球尺度的大气环流所造成的下沉气流所控制。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
