  The variation in the intensity of cosmic rays at small angular scales is
attributed to the interstellar turbulence in the vicinity of the Solar system.
We show that {a turbulent origin of the small-scale structures implies that}
the morphology of the observed cosmic-ray intensity skymap varies with our
location in the interstellar turbulence. The gyroradius of cosmic rays is shown
to be the length scale associated with an observable change in the skymap over
a radian angular scale. The extent to which the intensity \mpo{at a certain}
angular scale varies is proportional to the change in our location with a
maximum change of about the amplitude of intensity variation at that scale in
the existing skymap.} We suggest that for TeV cosmic rays a measurable
variation could occur over a time scale of a decade due to the Earth's motion
through the interstellar medium, if interstellar turbulence persists down to
the gyroradius, \mpo{about $00\ \mu\mathrm{pc}$ for TeV-ish cosmic rays}.
Observational evidence of the variability, or an absence of it, could provide a
useful insight into the physical origin of the small-scale anisotropy.
