我们提出了长周期惯性重力波和与波传播有关的晴空湍流事件的同步原位测量。波-湍流相互作用的能量收支表明，长周期和短垂直波长的波可以在接近剪切不稳定条件的几个波长上向上传播。这一结果使人们能够解释文献中报道的CAT层的时空结构，特别是它们的水平和垂直范围、厚度和持久性。
We present simultaneous in situ measurements of a long-period inertio-gravity wave and of clear air turbulence events associated with wave propagation. The energy budget of the wave-turbulence interaction shows that a wave of long period and of short vertical wavelength may propagate upward over several wavelengths close to the shear instability conditions. This result allows one to interpret the spatiotemporal structure of CAT layers as reported in the literature and in particular their horizontal and vertical extent, their thickness, and their persistence.
