查询词典 wet air

Results show that during the snowstorm disaster, under the large scale background with "trough in south and ridge in north", strong cold air caused by prevailing northerly wind in northern Asia wedged into low level atmosphere over Southeast China and formed a "clod cushion". At the same time, warm-wet air was also transported to Southeast China by southerly wind. The vertical shear of winds from cold to warm airflows produced strong upward motion and then, the warm-wet air over the cold air wedge was driven to rise. Finally, the structure of "warm cover" and "cold cushion", as well as corresponding vertical circulation over the converging frontal zone came into being.
