| 摘 要： | 在一个下部为弱不稳定层、上部为稳定层的二层模式中，求解线性化的大气动力—热力学方程组，表明一个孤立山丘所引发的重力内波，在向下游传播过程中与边界层中对流相互作用，形成大气低层的涡漩活动，其图象与观测到的对流云街结构相似。

| Abstract: | By using a two layer model the linear atmospheric equations system is solved analytically to study the disturbed flow fields induced by an isolated hill. The solutions show that the initiated internal waves propagating downstream in the upper stable layer interact with the convections in the lower convective layer and form the large vortices with structure similar to that observed in the convective cloud streets. |
