我们研究了球面上一些简单的两层模型的斜压不稳定性问题。我们发现,随着波浪的增长,存在着巨大的动量输运。这些输运是由球面几何的其他方面引起的,而不是包括在-平面分析中的那些方面。另一方面,-平面很好地描述了波的基本动力学。
We examine the baroclinic instability problem in some simple two-level models on a sphere. We find that there are large momentum transports associated with the growing waves. These transports are induced by aspects of the spherical geometry other than those included in the beta-plane analysis. On the other hand, the beta-plane gives a good description of the essential dynamics of the waves.
