We revisit the issues of sensitivity to initial flow and intrinsic variability in hot-Jupiter atmospheric flow simulations, issues originally investigated by Cho et al. and Thrastarson & Cho. The flow in the lower region (∼1 to 20 MPa) ‘dragged’ to immobility and uniform temperature on a very short time-scale, as in Liu & Showman, leads to effectively a complete cessation of variability as well as...
