  Giant planets that reside in close proximity to their host stars are subject
to extreme irradiation, which gives rise to thermal ionization of trace Alkali
metals in their atmospheres. On objects where the atmospheric electrical
conductivity is substantial, the global circulation couples to the background
magnetic field, inducing supplementary fields and altering the nature of the
flow. To date, a number of authors have considered the influence of a spin-pole
aligned dipole magnetic field on the dynamical state of a weakly-ionized
atmosphere and found that magnetic breaking may lead to significantly slower
winds than predicted within a purely hydrodynamical framework. Here, we
consider the effect of a tilted dipole magnetic field on the circulation and
demonstrate that in addition to regulating wind velocities, an oblique field
generates stationary non-axisymmetric structures that adhere to the geometry of
the magnetic pole. Using a kinematic perturbative approach, we derive a
closed-form solution for the perturbed circulation and show that the fractional
distortion of zonal jets scales as the product of the field obliquity and the
Elsasser number. The results obtained herein suggest that on planets with
oblique magnetic fields, advective shifts of dayside hotspots may have
substantial latitudinal components. This prediction may be tested
observationally using the eclipse mapping technique.
