high pressure ridge

基本解释

A high-pressure ridge that has set up over the Southern Plains has been really persistent there. It has pushed a lot of active or violent weather to the east.
阿尔恩特说，“在南部平原区形成的高压脊十分顽固，引起了其东部地区活跃甚至是猛烈的天气现象。”
The high pressure ridge partially collapsed to the southeast leads to mid- die-high latitudinal strong cold air turning to southeast on a large scale, and strong cold wave weather is formed.
由于高压脊部分东南垮，导致中高纬度强冷空气大举东南下，造成强寒潮天气过程；
Especially the Middle East jet stream is weakened. Because a high pressure ridge develops from East Europe to the Caspian Sea, the perturbations of the westerly belt could hardly reach East Asia.
尤其是副热带中东急流减弱，从欧洲东部到里海为高压脊控制，西风带的扰动系统不易东移到东亚上空；
