| 摘 要： | 本文通过对2001年1月的一次强冷空气过程分析，总结出在500hPa南槽北脊高低纬反位相配置形势下，不利于冷空气南下越时南岭，低层冷空气只能在南岭北侧堆积，但当冷空气堆积到南岭两侧温差超过10℃以上，南岭以北的冷空气积聚已达临界值，一次不太强的冷空气补充也会使冷空气冲破南岭屏障，这时影响广东的冷空气已经是前几次叠加，强度明显加强。

| Abstract: | A strong cold process in January,2001 was analyzed in this paper.The result showed that at reversad phase situation in 500 hPa with a trough in the lower latitude and a ridge in the higher latitude,the cold air was blocked by the Nanling and was deposited to the north of Nanling range.When the temperature differences between the both sides of Nanling range were over 10 degrees centigrade, a weak cold air supply can make the cold air deposited to the northern side of Nanling range stride over the Nanling range successfully. At the same time,cold air was intervisfied obviously. |
