  For groups of photospheric magnetic fields differing in strength the time
averaged synoptic maps were obtained on the basis of the National Solar
Observatory Kitt Peak data (1976-2003). The latitudinal profiles of magnetic
field fluxes were considered separately for each 5 G interval of the field
strength B. The changes both of the profile maxima and of the latitudinal
localization of these maxima were studied. The obtained results show that the
latitudinal distribution of magnetic fields considerably changes at certain
values of the field strength: 5 G, 15 G, and 50 G. The magnetic flux for field
groups differing in strength, monotonically decreases with increase of strength
for all fields with strength B>5 G. For these fields the fluxes of the southern
hemisphere exceed fluxes of the northern hemisphere. A very special group is
represented by the weakest fields B<5 G, which are in antiphase both in
localization and in time changes with stronger fields.
