Lower-Level Jet Streams of Large-and Meso-Scale Heavy Rain

大、中尺度低空急流与暴雨

At high altitude you have jet streams, and the wind velocity is not the same at all altitudes.

在高海拔处会有高速气流，风速在不同的海拔处，并不相同。

The radial velocities of wide spaced two jet and four jet impinging streams have been measured by Dual PDA with different nozzle diameters and primary velocities.

采用DANTEC公司的三维激光动态粒子分析仪（Dual PDA）测定了大喷嘴间距同轴对置两流股及四流股撞击后的径向速度分布。

The supergeostrophic behavior of low level jet streams is caused by the nonequilibrium relating to the jet strengthening or weakening instead of the quasi-equilibrium of the saturated moist air.

暴雨地区急流的超地转现象并不是饱和湿空气的难平衡现象，而是与急流加强减弱有关的不平衡现象；

The development of gas jet streams as well as velocity and temperature fields was illustrated.

得出了烧嘴射流的发展过程以及烟气速度场和温度场的分布特征。

Hot-jet is divided into two streams when the aspect ratio at nozzle throat section ( ARt) becomes 2.

在收扩喷管喉道宽高比（ARt）为2时，热射流被分成两股。

Owe to the coupling of upper and lower tropospheric jet streams, sinking motion to the left side of upper jet streams score and ascent between the right side of upper jet streams score and the left side of the lower jet stream score produce the secondary circulation.

由于高、低空急流耦合，高空急流中心左侧产生的下沉运动和高空急流中心右侧、低空急流左侧产生的上升运动在锋面上形成一次级环流。
