| 摘 要： | 本文用线性化全球原始方程谱模式来研究地形强迫行星波的垂直传播过程及演变特征.模式的积分结果表明:行星波的能量沿两支波导进行传播,在波从对流层向平流层传播中,极地波导起着主要作用.由于重力波破碎的阻尼作用,地形强迫的行星波无论它的波作用量或振幅都呈现振荡状态.

| Abstract: | The vertical propagating process and evolutive characteristics of planetary waves forced by topography are investigated by a global linearized primitive equation model. The results integrated by this model show that the energy of planetary waves can propagate along two wave guides, and the polar wave guide may play a main role in the propagations of planetary waves from the troposphere to the stratosphere. Due to the damping effect of gravity wave breakdown, both the wave activity and the amplitude of planetary waves forced by topography appear an oscillation. |
