從西伯利亞南下的寒冷空氣，它的厚度總是有限的，在南下的過(guò)程中，遇到低矮的丘陵山地時(shí)，還能蜂擁而過(guò)，但是一遇到高大巍峨的山脈時(shí)，它就會(huì)受到攔阻，常常要停留一段時(shí)間才能越過(guò)或繞過(guò)山脈繼續(xù)南下。在當(dāng)?shù)剌^強(qiáng)太陽(yáng)輻射的“烘烤”下，冷空氣迅速變暖，這樣一來(lái)，越過(guò)山去的冷空氣寒冷程度就大大減弱了。所以盡管最初冷空氣可以冷到-40℃至--50℃，可是當(dāng)它到達(dá)華南地區(qū)的時(shí)候已經(jīng)大大增暖，并不能使當(dāng)?shù)氐臉?shù)葉變黃脫落，也不會(huì)使河面上出現(xiàn)薄冰。
