论文摘要
在本文中，我们研究了{\ it f}平面中辐射传染边界附近的惯性和重力波传播。已经考虑了两种配置：波从对流层传播到辐射分层的稳定层，或者在本文中，我们研究了{\ it f}平面上辐射偏向边界附近的惯性和重力波传播。已经考虑了两种配置：波从对流层传播到辐射分层的稳定层，或者相反。已经发现，当稳定层分层（$ n^2/（2Ω）^2> 1 $）时，波浪更喜欢在低纬度生存。但是，如果稳定层被弱分层（$ n^2/（2Ω）^2 <1 $），但是，如果子午波数较大，则波浪可以在任何纬度上生存。然后，我们讨论了两个浮力频率结构的传输比：均匀分层和连续变化的分层。对于均匀的分层，我们发现当旋转速度快速或波浪接近临界层静脉时，透射率是有效的。对于连续变化的分层，当浮力频率是代数函数$ n^2 \ propto z^ν（ν> 0）$时，我们讨论了传输比。我们发现，当旋转速度快速，波浪接近临界层级时，或者分层层的厚度远大于水平波长时，传输可能是有效的。传输比不取决于配置（辐射层位于对流层上方，反之亦然；波浪向外或向内传播），而仅取决于波（频率和波数）和流体（分层程度）的特征。
In this paper, we study the inertial and gravity wave transmissions near the radiative-convective boundaries in the {\it f}-plane. Two configurations have been considered: waves propagate from the convective layer to the radiative stratified stable layer, or In this paper, we study inertial and gravity wave transmissions near radiative-convective boundaries on the {\it f}-plane. Two configurations have been considered: waves propagate from the convective layer to the radiative stratified stable layer, or the other way around. It has been found that waves prefer to survive at low latitudes when the stable layer is strongly stratified ($N^2/(2Ω)^2>1$). When the stable layer is weakly stratified ($N^2/(2Ω)^2<1$), however, waves can survive at any latitude if the meridional wavenumber is large. Then we have discussed transmission ratios for two buoyancy frequency structures: the uniform stratification, and the continuously varying stratification. For the uniform stratification, we have found that the transmission is efficient when the rotation is rapid, or when the wave is near the critical colatitude. For the continuously varying stratification, we have discussed the transmission ratio when the square of buoyancy frequency is an algebraic function $N^2\propto z^ν (ν>0)$. We have found that the transmission can be efficient when the rotation is rapid, or when the wave is near the critical colatitude, or when the thickness of the stratification layer is far greater than the horizontal wave length. The transmission ratio does not depend on the configurations (radiative layer sits above convective layer, or vice versa; wave propagates outward or inward), but only on characteristics of the wave (frequency and wavenumber) and the fluid (degree of stratification).
