| 摘 要： | 采用一个准地转两层波谱模式,进行了在热力强迫作用下阻塞的非常定演变过程的数值试验,试验结果说明了实际阻塞形成、维持及崩溃过程的一些典型特点。本文并用大量的控制性试验,探讨了波动与强迫源的非线性共振、强迫源对阻塞位相及强度的控制作用、各类平衡态稳定性等阻塞形势动力机制的问题。

| Abstract: | By using a two-level quasi-geostrophic spectral model,the numerical experiments on blocking process effected by thermal forcing are conducted.The dynamic mechanisms of blocking,including the resonance between wave and forcing,the control effects of thermal forcing on the position and the intensity of the highs and the instabilities of two kinds of equilibrium states,etc.,are studied by controlled experiments. |
