P\"aschke et al. (JFM, 701, 137--170 (2012)) studied the nonlinear dynamics
of strongly tilted vortices subject to asymmetric diabatic heating by
asymptotic methods. They found, i.a., that an azimuthal Fourier mode 1 heating
pattern can intensify or attenuate such a vortex depending on the relative
orientation of tilt and heating asymmetries. The theory originally addressed
the gradient wind regime which, asymptotically speaking, corresponds to vortex
Rossby numbers of order O(1) in the limit. Formally, this restricts the
appicability of the theory to rather weak vortices in the near equatorial
region. It is shown below that said theory is, in contrast, uniformly valid for
vanishing Coriolis parameter and thus applicable to vortices up to hurricane
strength. The paper's main contribution is a series of three-dimensional
numerical simulations which fully support the analytical predictions.Comment: 22 pages, 11 figure
