地形影响下冷锋的变形及锢囚

Distortion and occlusion of cold fronts under the influences of OROGRAPHY

当一个龙卷风被冷湿气流缠绕的时候就会形成锢囚锋。

Occlusion takes place when a single tornado is wrapped with cold damp air .

研究结果表明，暴雨天气是在有利的东高西低降水形势下产生的，其主要的触发天气系统是500hPa冷槽、700hPa高原低涡及地面锢囚锋。

The results show that the rainstorm weather was generated under the favorable " high east and low west " rainfall situation . The main triggering weather system is the 500 hPa cold trough , 700 hPa plateau low vortex and ground occluded front .

气旋锢囚期对流不稳定最弱。

The weakest convective instability is at the occluded stages of cyclone .

一些专家认为锢囚锋的过程有助于这些旋风的形成。

Some experts believe that the occlusion process is conducive to the forming of these twisters .

在气旋锢囚后，只有暖锋前的冷层和气旋中心水汽较多。

After cyclone occlude , there are only fine water vapor conditions at fore warm front and cyclone center .

冷涡云系的结构可归纳为单纯的冷涡结构和具有锢囚气旋结构两类。

The structure of cold vortex cloud system is catalogued by two types , the simple vortex structure and the occluded cyclone structure .

观察页突出显示了英国的地图，在其顶部具有包括完整冷、暖锢囚锋的挪威式旋风。

The observations page prominently features a map of the UK with a Norwegian-model cyclone over the top of it , complete with cold , warm and occluded fronts .

数值结果显示，在干大气中，高空西风急流的存在使锢囚锋非地转环流和锋区上升速度迅速变化、增强，并有利于重力内波的垂直传播；

The numerical results show that the upper level jet intensifies greatly the occluded frontal circulation and vertical velocity in frontal zone , and it is advantageous to propagate vertically internal gravity waves excited in frontal zone .
