Moreover, the cold air mass moving south is lifted by the blocking of Yunnan-Guizhou Plateau, and resulting in the convergence of moist air and strong ascending motion, which produce moist and dynamic condition for the formation of congeal.
在贵州重级凝冻天气过程中,北半球极涡偏心亚洲、东亚大槽异常偏南以及静止锋维持是重要成因;700hPa以下的逆温层有利于过冷却雨滴的形成,而较显著的“冷-暖-冷”平流的三层模式利于过冷却雨滴在及地前冻结形成凝冻;此外,南下冷气团遇云贵高原阻挡后被迫抬升,导致低层湿空气辐合和较强的上升运动为凝冻的形成提供了水汽和动力条件。
