这些机制可以大致说明一些爆发性增温期间平流层和对流层大气环流出现异常以及随后又恢复到正常冬季环流的过程。
These mechanisms can largely explain occurring of abnormal circulation in the stratosphere and troposphere during stratospheric sudden warming and returning then to normal regime.
当然，这些增温并非是由臭氧损耗的辐射效应直接造成的，而是通过波-流相互作用以及平流层-对流层相互作用等动力学过程实现的。
The warming is not due to direct radiative effect of ozone depletion, instead, it is throughout dynamic processes, such as wave-mean flow and stratosphere-troposphere interactions.
中高纬地区平流层在第1~16个月、第20~29个月出现2段增温，第1段增温时间跨度长、强度大，第17~19个月出现了降温。
In middle-high latitude regions, the stratosphere temperature has two obvious warming periods in 1~16th months and 20~29th months, but it is cooling in 17~19th months.
