摘要利用渐近多尺度方法，对所有经向波数的赤道波在具有垂直切变的平均场中垂直传播的一般问题进行了解析求解。结果表明，重力-罗斯比混合波不是唯一能够穿透平流层的东风波，而开尔文波是唯一能够穿透平流层的西风波。这些结果也被用来评价平均风对日潮的影响。
Abstract The general problem of the vertical propagation of equatorial waves through mean fields with vertical shear is solved analytically for all meridional wavenumbers using asymptotic multiple-scale methods. The results are used to show that the mixed gravity-Rossby wave is not the only easterly wave capable of penetrating the stratosphere, while the Kelvin wave is the only westerly wave capable of doing so. The results are also used to evaluate the effects of mean wind on diurnal tides.
