Dispersion of the solar magnetic flux in undisturbed photosphere as derived from SDO/HMI data
To explore the magnetic flux dispersion in the undisturbed solar photosphere,
magnetograms acquired by Helioseismic and Magnetic Imager (HMI) onboard the
Solar Dynamic Observatory (SDO) were utilized. Two areas, a coronal hole area
(CH) and an area of super-granulation pattern, SG, were analyzed. We explored
the displacement and separation spectra and the behavior of the turbulent
diffusion coefficient, . The displacement and separation spectra are very
similar to each other. Small magnetic elements (of size 3-100 squared pixels
and the detection threshold of 20 Mx sm) in both CH and SG areas
disperse in the same way and they are more mobile than the large elements (of
size 20-400 squared pixels and the detection threshold of 130 Mx sm).
The regime of super-diffusivity is found for small elements ( and growing from 100 to 300 km s). Large
elements in the CH area are scanty and show super-diffusion with and = (62-96) km s on rather narrow range of
500-2200 km. Large elements in the SG area demonstrate two ranges of linearity
and two diffusivity regimes: sub-diffusivity on scales (900-2500) km with
and decreasing from 130 to 100 km s,
and super-diffusivity on scales (2500-4800) km with and
growing from 140 to 200 km s. Comparison of our
results with the previously published shows that there is a tendency of
saturation of the diffusion coefficient on large scales, i.e., the turbulent
regime of super-diffusivity is gradually replaced by normal diffusion.Comment: 8 pages, 8 figure
