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.
阿爾恩特說，“在南部平原區形成的高壓脊十分頑固，引起了其東部地區活躍甚至是猛烈的天氣現象。”
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.
由於高壓脊部分東南垮，導致中高緯度強冷空氣大擧東南下，造成強寒潮天氣過程；
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.
尤其是副熱帶中東急流減弱，從歐洲東部到裡海爲高壓脊控制，西風帶的擾動系統不易東移到東亞上空；
