- Abstract
A distinctive feature of chromospheric magnetic fields in the facular regions on the Sun is their very fine spatial structure. In accordance with the observations performed in Ca II K and H line (the level of the lower chromosphere, about 0.5–1 Mm over the photosphere), numerous "slender fibrils mapping the magnetic field" were recorded. It is noted that "...the loops are organized in canopy-like arches" (Jafarzadeh et al., 2017). In this paper we perform some modification of the facular model presented by Solov'ev and Kirichek (2019) as a steady magnetic "fountain" with many thin trickles of plasma flows. The radial-azimuthal temperature profiles of the facula are calculated. It is shown that the difference in the vertical and horizontal scales of the system does not improve the correspondence between the model parameters of the faculae and their observed characteristics.
