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。 -
