  Under nonuniform convection, the distribution of diffusive particles can
exhibit dipole and quadrupole anisotropy induced by the fluid inertial and
shear force, respectively. These convection-related anisotropies, unlike the
Compton-Getting effect, typically increase with the cosmic-ray (CR) energy, and
are thus candidate contributors for the CR anisotropy. In consideration of the
inertial effect, CR observational data can be used to set an upper limit on the
average acceleration of the local interstellar medium in the equatorial plane
to be on the order of 100 $ \mu \text{m}/\text{s}^2 $. Using Oort constants,
the quadrupole anisotropy above 200 TeV may be modeled with the shear effect
arising from the Galactic differential rotation.
