Coriolis force acting on near-surface horizontal flows during simulations of flux emergence produces a tilt angle consistent with Joy’s law on the Sun

Kavli Affiliate: Robert Cameron | Summary:Joy’s law describes the tilt of bipolar active regions on the Sun away from an east-west orientation, where the flux of the polarity concentrated at the prograde side tends to be closer to the equator than the polarity on the retrograde side. Joy’s law is attributed to the Coriolis force […]
