对流层上部 meaning in English
u er tropo here
u ertropo here
upper troposphere
Examples
- The area is southwest of a tutt cell with weak eastward outflow and moderate equatorward outflow
94w最大的问题也就是高空辐散不够强了，和处于tutt （热带对流层上部槽）的西南侧有关。 - The dynamic response to the heating imbalance is such as to converge heat into the upper troposphere of the desert regions
对这一加热不平衡的动力学响应结果导致热在这沙漠地带的对流层上部辐合。 - Jet stream is an elongated belt of high speed air , typically found in upper tropospheric westerly flow round the globe . a jet stream may stretch over tens of thousands of kilometres in length from west to east and a few hundred kilometres in width from north to south
高空急流是围绕地球的一条强而窄的高速气流带，集中在对流层上部或平流层中，在中高纬西风带内或在低纬度地区都可出现。 - The analysis of dry pv shows that the high pv dominate the area of typhoon , the higher is the center value of pv , the stronger is the typhoon . lt is also shown that the most important reason resulting in rainstorm is the cold air ( high pv ) which spreads to south from the upper troposphere or lower stratosphere and transports into the warm air . the joining situation of upper and lower pv area make vortex develop . pv transpotation reduces static stability , which increases the releasing of instability energy and makes rainstorm amplify
对干位涡的分析表明：台风或台风环流区为高值位涡区，台风越强，位涡中心值越大；对流层上部或平流层下部冷空气(高位涡)的扩散南下与暖湿气流的交汇是造成特大暴雨的重要原因，因为上游斜压性的发展使对流层顶发生折叠，平流层与对流层相互作用增强，上下位涡区相接的形势使低层涡旋发展，上升运动加强，位涡的下传有效地降低了静力稳定度，有利于位势不稳定能量的释放，使得暴雨增幅。
