摘要:

用线性模型讨论了对流和加热对重力惯性波的激发,分别讨论了初始垂直速度扰动和初始位温扰动及大气内部加热在静态层结大气中激发的重力惯性波,及重力惯性波过程引起的大气温压场的变化。得到的结果可以帮助理解中小尺度系统的发生发展、对流过程与环境大气的相互作用。

Abstract:

A linear model is developed and used to study the inertia-gravity waves excited by convection and heating sources.The effects of initial vertical velocity preturbation,initial potential temperature perturbation and heating sources in the atmosphere on the excitation of inertia-gravity wave is investigated respectively.The effects of inertia gravity wave disturbances on the envionment atmosphere are also discussed.The results of this study may be of significace in understanding the generation and development of meso-and micro-scale disturbances and the interaction between the convection process and the environment atmosphere.
