frontal cloud 中文意思是什麼
frontal cloud
解釋
鋒面雲-
The main relative systems of heavy - hard rainfall in northeast plateau are western pacific subtropical high, south asia high, low latitude systems, upper level jet ( ulj ), low level greater wind speed axes, westerly trough and plateau trough, low level vortex, cold frontal, occluded front in qinghai lake, mesoscale low pressure, heat low - pressure in qinghai, shear line and convergence line, mesoscale cloud cluster, etc. the west subsidiary model of south asia high is the main circulation type of heavy - hard rainfall in this area
3 、西太平洋副高、南亞高壓、低緯系統、高空急流、低空大風速軸；西風槽和高原槽、低渦、冷鋒、青海湖錮囚鋒以及中尺度低壓、青海熱低壓、切變線與輻合線、中尺度雲團等系統是高原東北部地區大到暴雨的主要相關系統。 100hpa上的南亞高壓中心強度加強，位置東西擺動預示高原地區將有降水產生，中心強度減弱，降水過程結束。南亞高壓西部副型是高原東北部地區大到暴雨的主要流型。 -
The results show that unbalance force of atmospheric motion and the coupling reaction among convective cloud cluster and moisture frontal zone and low level jet lead to the continuation of strong convergence in low layer and the maintenance of torrential rain
分析結果發現，大氣運動非平衡強迫、凝結降水的非均勻分佈與強烈垂直風切變的耦合作用、 「濕度鋒」與低空急流的耦合相互作用通過促進低空輻合流的維持，導致了對流雲團和暴雨天氣的持續。 -
Because of the existence of meiyu precipitating cloud band the temperature dv is faint inside the meiyu trough and on account of large - scale prominent terrain available, significant temperature dv occurs on both sides of the trough, leading to the reinforcement of the subtropical high and middle latitude transformed high, and the deepening and narrowing of the trough in the night with the result that the relative intensity and precipitating function of the meiyu frontal rainfall system are changed at day and night, resulting in precipitation dv
由於梅雨雲帶的存在，梅雨鋒低壓槽內溫度日變化很微弱；由於梅雨系統四圍高大地形的存在，梅雨鋒低壓槽南北兩側溫度日變化非常明顯，使南海副高和中緯度變性高壓在夜間增強，梅雨鋒低壓槽也在夜間變深、變窄，改變了早、晚時刻梅雨系統的相對強度和降水功能，導致降水日變化。
