tropospheric wave
A radio wave that is propagated by reflection from a place of abrupt change in the dielectric constant or its gradient in the troposphere. In some cases, the ground wave may be so altered that new components appear to arise from reflections in regions of rapidly changing dielectric constants; when these components are distinguishable from the other components, they are called tropospheric waves.

In addition, they showed how spectral analysis could be used effectively to detect and to describe these and other synoptic-scale tropospheric waves (e.g., Yanai et al.
The 7ME has a weaker tropospheric wave guide (Figure 7(f)) than that of the OME, yet its stratospheric wave guide is slightly stronger than that of the OME.
