| 摘要: |
| 文中用斜压模式讨论了东风水平切变基流和非绝热加热对热带扰动的影响,指出:基本气流的切变有使西传波动加速,东传波动减速的倾向;切变会造成赤道Rossby波的不稳定发展;加热激发的赤道强迫波可以是垂直传播波. |

| Abstract: |
| It is shown that the shear in a easterly flow is of advantage for the instable deve lopmet of inertia-gravity waves and Rossby waves in the tropical zone. The equatorial forced waves excited by diabatic heating can propagate vertically. |
