On the origin of the prolate solar chromosphere

摘要: A simple geometric model is proposed to explain the recently reported effect of prolateness solar chromosphere. We assume that a specific dynamical part atmosphere above 2 Mm level, being mixture moving up and down jets chromospheric matter with coronal plasma between them, responsible for prolateness. Due dynamic nature this layer, magnetic field considered play very important role in density distribution height, guiding mass flows along lines. The difference topology polar equatorial regions leads different heights limb. Calculations show satisfactory coincidence observations when mean separation opposite polarity concentrations about 9 Mm. possible observational signature network low photospheric layers discussed.
