Cloud Electrification Model in COSMO Numerical Weather Prediction model
Original language description
We developed a Cloud Electrification Model (CEM) and implemented it in the microphysical scheme of the COSMO non-hydrostatic and convection-permitting 2-moment numerical weather prediction model. CEM explicitly describes the electrification of a thundercloud,, it explicitly treats the ion motion including the interaction of ions with six kinds of hydrometeors (cloud water, ice, graupel, rain, snow, and hail). Charge concentration within the hydrometeors as well as the change of the concentration are both computed by CEM within the cloud microphysical scheme of COSMO. The charging mechanism in CEM is primarily due to the non-inductive mechanism, which leads to the charge separation and transfer, although we consider the inductive charging mechanism in CEM as well. Based on simulations of an artificially induced thundercloud, i.e. warm air bubble, CEM shows rather complicated electric charge structure in the thundercloud. The concentration of the negative charges is mostly connected to high concentrations of graupel, ice, and snow that frequently collide to transfer their charges.
