HURMOD is an axisymmetric non-hydrostatic cloud-resolving atmospheric model. The governing model equations are mass-consistent, i.e. the removal of water mass by precipitation or supply of water mass by evaporation from the ocean surface is consistently calculated by the model. The equations are formulated in cylindrical coordinates r (radius), λ (azimuthal angle) and z (height) and are numerically integrated on an Arakawa C grid. The model adopts a Smagorinsky-Lilly parameterization for microturbulence and a Kessler scheme for cloud microphysics.
HURMOD is designed for the simulation of idealized tropical cyclones and convective clouds. The axisymmetry allows a much higher gridpoint solution than in full three-dimensional models since only two spatial coordinates exist.
