查询词典 meso

Exhibits a rare structure of a meso-helix which is a 3D presentation of a lemniscate. 14 and 15 are isomorphic one-dimensional helical structures.

The meso-scale convective cell in squall line causes severe convective wind.

由镶嵌在飑线中的小尺度超级单体造成对流性大风。

The result shows that the severe convection weather arise in the transition from verticality to forward slant of the upper trough, so there was a different advection between the mid- and lower- troposphere, which was quite important to the formation and development of convective instability. The event was triggered by the surface low and meso-scale convergence line, and the squall line was direct influencing system.

结果表明：这次强对流天气过程发生在高空槽由垂直结构向前倾结构转变的过程中，中高层干冷平流、低层暖湿平流的大气层结增强了对流不稳定的发展，飑线是此次强对流天气的直接影响系统；太行山地形和平原南部的中尺度辐合线，对飑线系统的触发、组织、移动具有重要作用，强对流区发生在地面中尺度辐合线南侧的偏南气流里。
