Observations of supercells from polarimetric radars have led to the identification of numerous polarimetric signatures. Often, however, it is difficult to infer internal storm dynamics and kinematic properties from such signatures given the very expansive parameter space characterizing the environments in which such storms occur. Given recent advances in multi-moment precipitation microphysics and the development of a polarimetric radar emulator, a series of supercells are simulated with a high-resolution numerical model. The primary objective of this project is to examine the influence of the vertical wind shear profile on the polarimetric representation of simulated supercells and to associate the evolution of polarimetric signatures with changes in storm organization.
