upward motion of air 中文意思是什麼
upward motion of air
解釋
空氣向上運動-
The quasi - geostrophic process was diagnosed for a case of severe cold air breakout under the blocking situation during 16 - 18 march of 1998. the attention was focused on the relationship between the surface anticyclone and 500hpa blocking high. the results indicate that the cold outbreak is associated with the adjustment of blocking situation in the ural area, i. e. the collapsing and rebuilding of the ural mountain blocking high. the temperature advections in the lower troposphere shown that the polar cold air invading from the northwest caused the ural blocking high collapsed, and a new ridge developed rapidly was due to the warm advection on the southwestern side which led to the ural blocking high rebuilt. in addition, the distribution of the vertical motion on 700hpa shown that the surface high splitting was related to the considerable upward motion located on the southeastern part of surface high
對1998年3月中旬一次高空阻塞形勢下強冷空氣過程進行了診斷分析，著重討論強冷空氣爆發前後地面反氣旋活動與高空阻塞形勢調整的關系。研究結果表明，強冷空氣的爆發與烏拉爾地區阻塞形勢的調整阻塞高壓的崩潰和重建緊密相關。對流層下部的溫度平流分析表明，阻塞形勢的調整是由於阻塞高壓上游西北方有冷空氣侵入導致了阻塞高壓的崩潰，而上游來自西南方向的強暖流則導致高壓脊迅速發展，使阻塞高壓重新建立。 -
With the arrival of the front, the relatively warm air being less dense became lifted by the advancing cold air. the upward motion resulted in convection, eventually producing thunderstorms over the western coast of guangdong, the new territories and lantau ( figs
當冷鋒抵達時，推進中的冷空氣使密度較低的暖空氣向上抬升，繼而觸發對流活動，其後為廣東西部沿岸、新界及大嶼山帶來雷暴（圖2至4 ） 。 -
