The contrast analysis for the vertical distribution feature of the simulated physical quantities such as vorticity, divergence, vertical velocity. spiral degree etc suggests that there are a good disposal among the various physical quantities fields in the different stage during the period of sandstorm development, and reveals that the dynamic mechanism of the forming, developing, decreasing of the sandstorm weather and trigger and indication effects of the micro - mesoscale systems and secondary vertical circulation to the occurring and developing of sandstorm in northwest area
對渦度、散度、垂直速度、螺旋度等物理量的水平和垂直分佈特徵進行對比分析，發現各物理量場在沙塵暴發展的不同時期有著很好的配置，揭示出西北地區沙塵暴天氣的形成、發展、消弱的物理機制和中小尺度系統、次級垂直環流對沙塵暴天氣發生發展的觸發和指示作用。沙塵暴區上空螺旋度垂直分佈為高層負值，低層正值，螺旋度大小的演變與沙塵暴的出現有一定的對應關系。
