This effect is magnified when the sun is close to the horizon and its light passes through the densest atmospheric layers.

当太阳接近地平面，光线穿越最浓密的大气层时，这种效应就会加强。

Of all the above atmospheric layers, only the troposphere (especially its boundary layer) is characterized by a marked instability of the vertical distribution of the meteorological parameters.
