  Recent measurements of the dipole anisotropy in the arrival directions of
Galactic cosmic rays (CRs) indicate a strong energy dependence of the dipole
amplitude and phase in the TeV-PeV range. We argue here that these observations
can be well understood within standard diffusion theory as a combined effect of
(i) one or more local sources at Galactic longitude 120deg < l < 300deg
dominating the CR gradient below 0.1-0.3 PeV, (ii) the presence of a strong
ordered magnetic field in our local environment, (iii) the relative motion of
the solar system, and (iv) the limited reconstruction capabilities of
ground-based observatories. We show that an excellent candidate of the local CR
source responsible for the dipole anisotropy at 1-100 TeV is the Vela supernova
remnant.
