Atmospheric Gravity Waves and Traveling Ionospheric Disturbances can be observed in the neutral atmosphere and the ionosphere at a wide range of spatial and temporal scales. Especially at medium scales, these oscillations are often not resolved in general circulation models and are parameterized. We show that ionospheric …
WebWe now know a little about the mechanism for refraction from the ionosphere. When a radio wave reaches the ionosphere, the electric field in the wave forces the electrons in the ionosphere into oscillation at the same frequency as the radio wave. Some of the RF energy is given up to this resonant oscillation. Web11 apr. 2024 · The claim: Video shows waves being modified by HAARP.
