Impact of cloud-radiative processes on hurricane track

Idealized simulations of tropical cyclones suggest that previously established motion sensitivity to cloud microphysical processes may emerge through cloud-radiative feedback. When commonly employed radiation parameterizations and absorption treatments are used, microphysical schemes generate a variety of tracks, influenced by different, scheme-dependent convective heating patterns and magnitudes. However, these variations nearly vanish when cloud-radiative feedback is neglected, with storms becoming stronger and more compact. This study strongly motivates further research with respect to how condensation particles influence radiative processes and thus storm dynamics and thermodynamics. Citation: Fovell, R. G., K. L.
