An adiabatic simulation of the ERICA IOP 4 storm: an example of quasi-ideal frontal cyclone development

Numerical experiments with dry, inviscid models started from small normal-mode perturbations in baroclinic jet flows provide examples of ideal baroclinic cyclone development.

Description
Summary:Numerical experiments with dry, inviscid models started from small normal-mode perturbations in baroclinic jet flows provide examples of ideal baroclinic cyclone development. This paper examines, with use of the Pennsylvania State University-National Center for Atmospheric Research Mesoscale Model, cyclone development under conditions that resemble the ideal experiments in lacking initial surface fronts and in neglecting latent heating and surface fluxes but that differ from most ideal experiments in including surface friction and an initial large upper-level disturbance. The initial state of the simulation is that of the intense, explosive Experiment on Rapidly Intensifying Cyclones over the Atlantic intensive observation period 4 storm. Issues highlighted are the timing and rate of deepening, the rapidity and intensity of frontal formation, the frontal structure, the airflow relative to the cyclone and fronts, and the nature of the occlusion and warm-core seclusion processes.
