westerly trough meaning in Chinese
西风槽
Examples
- The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high , south asia high , low latitude systems , upper level jet ( ulj ) , low level greater wind speed axes , westerly trough and plateau trough , low level vortex , cold frontal , occluded front in qinghai lake , mesoscale low pressure , heat low - pressure in qinghai , shear line and convergence line , mesoscale cloud cluster , etc . the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亚高压、低纬系统、高空急流、低空大风速轴；西风槽和高原槽、低涡、冷锋、青海湖锢囚锋以及中尺度低压、青海热低压、切变线与辐合线、中尺度云团等系统是高原东北部地区大到暴雨的主要相关系统。 100hpa上的南亚高压中心强度加强，位置东西摆动预示高原地区将有降水产生，中心强度减弱，降水过程结束。南亚高压西部副型是高原东北部地区大到暴雨的主要流型。 - While the precipitation of southeast of inner - mogolio is attributed as the strong convective precipitation , the rainfall of liaoning and northeast of heilongjiang is induced by subtropical high and westerly trough , and that of west of heilongjiang is influenced directly by vortex in upper air
各区域产生极端降水的天气背景也不相同：内蒙古东南部的降水是前倾槽引起的强对流降水天气，辽宁和黑龙江东北部的降水是由于副热带高压和西风槽的共同作用引起的。黑龙江西部的降水是由于高空涡的直接作用引起的。 - The summer rainfall anomaly of north china is closely related to indian low , west pacific subtropical high , westerly troughs and ridges in mid - latitude , south asia high , subtropical monsoon circulation and cold air activity on the corresponding period , and similar circulation pattern also appears in the preceding spring
结果表明： ( 1 )华北夏季降水异常与同期印度低压、西太平洋副高、中纬度西风槽脊、南亚高压、副热带季风环流和冷空气活动的异常都密切相关。华北夏季降水异常年春季的环流特征与夏季类似。
