Meteors+Wind Shear+Lorentz Force At the moment the most accepted theory to explain the formation of the sporadic E (ES) region of the ionosphere is wind shear, but this theory does not fully explain the formation of the ES region. I have conducted further studies and hypothesized another model, always connected to wind shear, but that introduces the contribution of meteors that ionize at the 100 km altitude, with the electrons concentrated in a dense layer by Lorentz Forces. I will call this model “Wind Shear and Lorentz Force.” The previous models and theories considered an accumulation of ions. How is this theory different? The change concerns the concentration of free electrons, not positive ions, because the electrons are responsible for ionospheric refraction, as we will see.  (Full Story) Contact: [email protected] Copyright  2013 © Amateur Radio Propagation Studies.
