锢囚锋(Occluded Front)，暖气团、较冷气团和更冷气团相遇时先构成两个锋面，然后其中一个锋面追上另一个锋面，即形成锢囚锋。我国常见的是锋面受山脉阻挡所形成的地形锢囚；或冷锋追上暖锋，或两条冷锋迎面相遇形成的锢囚。它们迫使冷锋前的暖空气抬离地面，锢囚到高空。
这一段的锢囚锋和高空暖舌带来与极地空气团天气相反的变化。
The passage is an occluded front and trowal brings a change back to polar air-mass weather.
利用原始方程模式探讨了高空西风急流和低空南风急流中锢囚锋环流的演变和增强机制。
The evolution and enhancement of occluded frontal circulation in upper-level westerly jet and lower-level southerly jet are discussed by using a dry primitive equation model.
当极地槽和主要的极锋相互作用，会产生不同的过程，会引起短暂的锢囚。
A different process occurs when there is interaction between a polar trough and the main polar front, giving rise to an instant occlusion.
