Sporadic E Theory. I. Collision-Geomagnetic Equilibrium

摘要: Abstract A simple equilibrium theory of ionization transport in the ionosphere is described which predicts a tendency for thin layers overdense (sporadic E layers) to form E-region. Such can be produced by dominance any five mechanisms convergence. Three these involve neutral wind shear and two wind. The assumes that ambipolar diffusion electrons heavy positive ions takes place under influence forces due collisions geomagnetic field. layer formation strongest principal part convergence mechanism lower E-region at those altitudes where vorticity antiparallel field, land upper perpendicular field westward (eastward) sense northern (southern) hemisphere. t...
