西风带

The results indicated that the effect of deep warm-wet air coming along the behind subtropical high , moving eastward deepening upper trough , shear line and cyclone trough was caused in Zhuanghe , but no strong thunderstorm . The main impact of system is surface cyclone trough ; Low vortex , shear line in 700hPa , 850hPa strengthen the lower convergence , forming a strong momentum of increase and pieces of water vapor ; strong and wide potential pseudo-equivalent temperature frontal zone lied in Zhuanghe area , the establishment of potential instability are indispensable conditions for producing heavy rain .

结果表明：受副热带高压后部深厚的暖湿气流及西风带高空槽、切变线及气旋倒槽等动力系统共同影响，庄河地区出现了大暴雨天气，但没有出现强雷暴，此过程主要影响系统是地面气旋倒槽；700hPa、850hPa低涡、切变线使中低层辐合加强，形成了较强的动力抬升和水汽辐合；庄河地区处于强而宽的假相当位温锋区中，位势不稳定的建立是造成此次强降水的必要条件。

Casethat begin transformation but do not become embedded in the baroclinic zone fail to complrte transformation and simply dissipate over lower sea surface temperatures.1at transformation stage,there are two features in 500mb analysis aKOPPU s surface center is located beneath concentric,closed 500mb contours and is equatorward of 5820-m contour associated with a short-wave trough to the northwest of strom bthe closed contours associated with KOPPU 24h earlier have combined with approaching 500mb trough so that KOPPU appear to be in an open wave.furthermore,streamlines associated with this short wave trough have wrapped around the circulation of KOPPU,which indicated that KOPPU has become embedded in 500mb westerlies.

台风变性分为两个阶段：变性阶段和再加强阶段；变性的开始和结束以热带气旋环流和先前存在的中纬度斜压带相互作用为基础，KOPPU嵌入先前存在的中纬度斜压带且风暴中心在冷下沉气流中，而KETSANA没有嵌入先前存在的中纬度斜压带则没完成变性只是消散在低的海平面温度(1)台风变性阶段在500hPa高度场分析中有两个重要特征：a首先风暴中心是闭合的等值线并和风暴中心西北的短波槽相关；随后闭合等值线靠近500hPa槽，因此风暴闭合中心消失，风暴位于开波中。b而且和短波槽相关流线缠绕在风暴中心，结果风暴在西风带中。

At this period, the summer monsoon became strong and carried more moisture to the Tibetan Plateau for high summer solar radiation over Indian Ocean and the Tibetan Plateau, and at the same time, for the Laurentide and Eurasia ice sheets, the westerly shifted southward.

40～28kaBP(MIS3a)，是距今最近的一次泛湖期，可称之为末次泛湖期，是在低纬度夏季高太阳辐射作用下，西南季风加强，同时由于北方冰盖的存在而使西风带相对南移，冷空气频繁影响高原，两种气流的交互影响，从而造成了高原的丰沛降水与环境湿润，是高原形成泛湖景观的直接原因。

The flow field construct of meso-β cloud clusters which bring the heavy-hard rainfall in northeast plateau is that the low level cloud cluster is located in the south of converging region, the southern low level influx converged in the cloud cluster and have some affection on the setting up of the rainstorm in the low level. In the middle level, the cloud cluster is lied in near the westerly trough and the southwest airflow ahead of the trough constantly transmits water vapor to the cloud cluster. In the high level, there are a pair of high and low pressure centers around cloud clusters and are obvious divergence airflow, and there is weak ageostrophic high level outflux along pressure force.

产生高原东北部地区大到暴雨天气过程的中—β尺度云团的流场结构特征是：在低层，云团位于辐合区的南部，低层的偏南低空入流在云团内辐合，对大到暴雨的形成有一定的作用；在中层，云团位于西风带低槽附近，槽前的西南气流不断地给云团输送水汽；在高层，云团附近有一对高、低压中心，为明显的辐散气流，沿气压梯度力方向有强度不强的非地转高空出流。

The frequencies of fog and poor visibility are indicated on the Routeing Charts and the subject is treated at length in the relevant Admiralty Sailing Directions. In the region of the Westerlies, overcast skies, with periods of rain or snow, alternate with brief fine spells. Cloud amounts are generally large. The part of the North Atlantic Ocean most affected by fog lies E and S of Newfoundland.

持续的大雾和极低的能见度都在航路图上表明出来，所有的具体情况由相关的航路指南最终来决定，在西风带地区，阴天，一段时间的雨或雪，交替出现短暂细雨，云非常多，大西洋一部分地区洋会被出现在纽芬兰东南边的大雾所影响。
