warm ridge
解釋
暖高壓脊-
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。 -
The results show that a warm high ridge at the middle level and transformed surface cold high over the plain provide a good background condition ; a cooling process produced by net surface radiation fluxes is the trigger and strengthening mechanism for the fog event ; the subsidence flow at the middle and low tropospheric levels is favorable for the setting - up and maintenance of stable stratification at the boundary layer and weak wind condition at the ground layer over the fog region ; the transportation of weak warm advection at lower levels and weak lift motion at the boundary layer play a very important role to the long maintenance of the fog event ; the intrusion of north wind accompanied by cold advection is a main dynamic factor of the fog dissipation
結果表明：在中高層暖性高壓脊及地面變性冷高壓穩定維持的大尺度背景條件下，地表凈輻射引起的近地層冷卻是大霧過程的觸發和加強機制；中低空下沉氣流的存在有助於近地層的弱風條件和穩定層結的建立；低層暖平流的輸入和邊界層的淺層抬升是大霧長時間持續的原因；伴隨冷空氣南下的偏北大風是驅使大霧消散的動力因子。
