frontal rainfall 中文意思是什麼
frontal rainfall
解釋
鋒面降雨-
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 result shows that the dynamic field and thermodynamic field in the zone of the meiyu front have obvious meso - scale structure characters, the meiyu frontal rainfall is caused by a series of meso - scale convective systems in the zone of meiyu fron t, the dynamic field and thermodynamic field corresponding to the meso - scale convective systems take on evident meso - scale structure, the structure of the dynamic field and thermodynamic field will adjust correspondingly in the course of the development of the meso - scale convective systems, what ' s more, the adjustments and the changes of the physical parameters will restricted the development and transformation of the meso - scale convective systems in reverse
試驗結果表明，梅雨鋒帶內的動力、熱力場具有明顯的中尺度結構特徵，梅雨降水是由梅雨鋒帶內的一連串中尺度對流系統造成的，中尺度對流系統對應的動力場、熱力場均呈明顯的中尺度結構，中尺度對流系統發生發展過程中，其伴隨的動力、熱力場結構均會作相應的調整，這些物理量場的調整和變化又制約了中尺度對流系統的發展變化。 -
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。
