Gaining for many years research results of tropospheric radio waves diffraction and scattering on the drops fractal ensemble are reported. It is shown that fractal turbulent airspace vortex-like disturbances produce the fractal fluctuations oif the atmospheric refraction and absorption indexes result in fractal fadings of the millimeter-band and sub-millimeter-band radio waves. Also shown that RF, sub-millimeter and optical signals fadings could be consider to be fractal ones at the framework of statistical self-similarity model. In according with presented experimental results in the center of the oxygen absorption line the fading amplification and attenuating phenomenons are observed that have a qualitative explanation within the fractal fluctuations theory in the absorption media. Substantiated that such phenomens as precipitation zones, cloud-like formations, dust and aerosol clouds, atmospheric turbulences, and so on could be attributed to multi-fractal media.
