1) low-level jet stream
西风低槽
1.
The main affecting systems include landfall typhoon,low-level jet stream and west trough.
主要影响系统为登陆台风、西风低槽和低空急流。
2) westerly trox
西风带低槽
3) Westerly low trough
西风(南支)低槽
5) westerly trough
西风槽
1.
The results are as follows: the strength and speed of westerly trough, the form changes and movement of the West Pacific subtropical high, the strength and southward path of cold air, and the internal asymmetry structure of the tropical cyclones are the main reasons for their different track.
结果表明:西风槽的强弱和东移的快慢、西太平洋副高的形状变化和东退西进、冷空气的强弱和南下路径及热带气旋内部的不对称结构是造成二者移动路经差异的主要原因。
2.
With non-hydrostatic meso-scale model MMS, the impacts of typhoon and westerly trough on the rainfall occurring in front of westerly trough far from the typhoon are analyzed in this paper.
利用ＭＭ５模式分别模拟了台风、中纬度西风槽对台风远距离槽前降水的影响。
3.
Computer simulation results show that the occurrence of the duct is caused by westerly trough and northward typhoon,in addition,maximum value(greater than 2 PVU,generally) region of potential vorticity is corresponding to duct region,which is one of important research approaches for duct forecasting and mechanism.
数值模拟分析表明:此次悬空波导的发生是西风槽等系统携带的冷空气与北上台风共同作用引起的,同时位涡场极大值区域(极大值一般大于2PVU)与大气波导出现的区域相对应,分析位涡场变化可作为大气波导机理和预报研究的途径之一。
6) south-west trough
西南低压槽

【诗文】：
西风来几日，一叶已先飞。
新霁乘轻屐，初凉换熟衣。
浅渠销慢水，疏竹漏斜晖。
薄暮青苔巷，家僮引鹤归。
