The Tilt Of Hurricane Bill's Eye

Frank sent this interesting link regarding Hurricane Bill.

I remember learning in dynamic meteorology that, as one goes from lower to higher elevations in closed circulations, there is a marked tilt of the circulation towards colder air, with the magnitude of the tilt dependent on the horizontal temperature gradient.

Hurricane Bill’s radar reflectivity diagram actually shows the rightward tilt of the eyewall, consistent with colder air being located towards the right.
