    結果表明：沙塵暴是在乾旱少雨的有利的氣候背景下產生的。斜壓槽和蒙古氣旋是觸發這次強沙塵暴天氣過程的重要的天氣系統，高空斜壓槽和強鋒區促使了地面蒙古氣旋的發展和冷鋒的加強，誘發沙塵暴天氣。高空急流及其下方的ferrel環流起到了高層動量下傳和加強低層鋒區的重要作用。
  3. Mackerel sky, not twenty - four hours dry describes the deterioration of weather after the appearance of cirrocumulus clouds. although it may be bright at the beginning, the weather will deteriorate in half a day s time as the cyclone or front approaches. as they pick up more moisture, the cirrocumulus clouds thicken and extend downward to become low - level clouds which bear rain

    魚鱗天，不雨也風顛是形容卷積雲出現後天氣轉壞的狀況，雖然初時天氣明朗，但約半天光景后，天氣會隨氣旋或鋒面的移近而轉壞，風速增強，卷積雲也會隨著水氣增加而逐漸增厚，雲層向下伸延轉為低層雲，產生降雨。
  4. Chen et al noted that there are three kinds of landfall typhoon tracks ; subtropical high and polar front, whose evolutions and adjustments may modify typhoon movement, are the main synoptic systems which influence the track of landfall typhoon

    陳聯壽等根據（ 1949 - 1976 ）年資料，指出：登陸臺風路徑可分為三類；副熱帶高壓和極鋒是影響熱帶氣旋陸地路徑的主要天氣系統，它們的演變和調整會影響熱帶氣旋的移向。
  5. Atmospheric systems responsible for stratiform precipitating clouds in henan during spring and autumn are low pressure ? cold front, and surface cyclone

    造成河南春秋季層狀降水雲系的主要天氣系統有低槽冷鋒和地面氣旋兩大類。
  6. The diagnostic analysis for the sandstorm process on the base of height, temperature, pressure and wind etc output from the model shows that the upper cold trough, low - level wind shear, surface cold anticyclonic ridge, mesoscale cyclone and cold front are the main synoptic systems, surface cold anticyclonic ridge and cold front provide condition of wind force to occurrence of the sandstorm weather, the strong mesoscale cyclone before front makes pressure gradient before and after cold front obviously strengthen, moreover, and it increases obviously the temperature of the controlled area, as a result, the updraft movement caused by convergence before front strengthens

    500hpa強鋒區、 700hpa切變和鋒前中尺度系統的強弱及位置變化是沙塵暴天氣發生發展到減弱的直接原因。地面冷高壓、地面氣旋及冷鋒是造成本次沙塵暴天氣的主要地面天氣系統。地面冷高壓及冷鋒為沙塵暴天氣的發生提供了風力條件，而中尺度氣旋使冷鋒前後氣壓梯度明顯增強外，又使所控制的區域增溫明顯，使鋒前輻合上升運動加強，為沙塵暴天氣的發生提供了熱、動力條件。
  7. The occurrence of cirrocumulus clouds indicates the distant presence of a convergent zone such as a pressure tough or a cyclone in lower levels ; or a frontal zone where cold air meets moist warm air. vigorous convection and lifting motion bring water vapour up in the sky where the water vapour sublimes into ice crystals, forming the high clouds

    卷積雲的出現顯示遠處地方低層有一強輻合帶如低壓槽或氣旋或鋒面即暖濕空氣碰到冷氣團，向上爬升的交界面形成，強烈的對流和抬升運動將水汽帶到高空，在那裡水汽直接升華變為冰晶而形成高層雲。
  8. The mid - level short wave trough could induce cyclone in the meiyu front to produce associated heavy rainfall

    適當強度的高空槽可以誘生梅雨氣旋，產生鋒面氣旋暴雨。
  9. Embedded in a large - scale cold front - cyclone are often meso - and small - scale wet thermal / dynamic structures that are uneven, with a huge cold " cushion " at low levels, frequent meso cold surges and related potentially unstable zones at middle levels

    在大尺度冷鋒氣旋天氣系統中，嵌有不均勻的中小尺度濕熱力動力結構。表現為低層大尺度冷墊、中空不斷出現的中尺度「冷涌」及對應的位勢不穩定區。
  10. A family of frontal cyclones over the western atlantic ocean. part ii : parameter studies. zhang da - lin, radeva, ekaterina, gyakum, john. monthly weather review, 127 ( 8 ) : 1745 - 1760

    進行了一系列敏感度試驗，從而考察了潛熱加熱、地面磨擦和地面熱通量對西大西洋上一鋒面氣旋族發展的相對影響。
  11. A transverse secondary circulation is produced by the coupling of high and low jets, while the sinking branch of the secondary circulation providing the dynamic conditions for the dry intrusion air. during the period of the heavy rain process, dry intrusion descends southward along the intense constant potential temperature lines, which promotes the lower cyclone. in addition, the pouring of upper - level dry air not only decreases ground temperature behind the front but also increases surface pressure and velocity

    由於高、低空急流耦合，在高空急流中心左側產生的下沉運動和高空急流中心右側、低空急流左側產生的上升運動在鋒面上形成一次級環流，次級環流的下沉支運動為對流層高層干空氣和高位渦的下傳提供了動力條件；進一步研究發現，干侵入沿相當位溫密集帶向南向下伸展，引起對流層低層氣旋性渦度的發展；此外，高層乾冷空氣向下注入，導致地面溫度降低、氣壓升高、風速加大、低層輻合增強、上升速度加大，從而促進了新的對流運動，引起降水增強。
