天气尺度波激发的阻塞流的生命循环:观测结果和数值试验

通过观测研究证实了天气尺度波激发的阻塞流的生命循环是频散和非频散之间的转换过程。除此之外，进行了一个数值试验，发现天气尺度波似乎对阻塞的形成和支配作用，而地形似乎起位相锁相的作用。同时可以发现天气尺度波在阻塞的产生过程中分裂成两支。这些结果支持了我们所得到的观测结果。

Life cycles of blocking flows associated with synoptic—scale eddies: Observed results and numerical experiments

An observational study is presented to confirm that the life cycle of blocking associated with synoptic-scale eddies is a transfer process between dispersion and nondispersion. In addition, numerical experiments are conducted. It is found that the synoptic-scale eddies seem to play a dominant role in the amplification of blocking, while the topography effect appears to play a phase-locking role. At the same time,the synoptic eddies tend to split into two branches during the onset of blocking. This supports the observational results obtained.
