| 摘 要： | 本文引入第二科里奥利参数讨论了中低纬过渡地区含非绝热(潜热)作用的对称扰动波包发展问题。结果表明:这一地区扰动波包的发展不仅包含了中高纬度波包发展条件［1］，而且与潜热和基本风场梯度经向切变及波包传播的非垂直性有关。过渡地区基本风场的作用是通过第一和第二科里奥利参数完成的。

| Abstract: | This paper studies the symmetric development of mesoscale disturbances with non-acsabatic (latent heat) heating in the transition zone of mid-low latitudes. The results show that the synmetric development of disturbances not only contains the conditions of development of the wavepacket inmid-high latitudes, but also is related to the latent heat and non-verticality of basic now shear gradientwith a wave packet speed. The action of the basic flow in the transition zone of mid-low latitudes depends on the first and the second Coriolis parameters. |
