Short summary
Lightning is important in atmospheric chemistry models as a source of nitrogen oxides which affect the greenhouse gases ozone and methane. We present a new approach to modelling lightning using the upward movement of ice in clouds, an essential part of the charging mechanism in thunderstorms. The new approach performs well compared to those already in use and provides a novel, physically based scheme that has the potential to improve the robustness of simulated flash rates and emissions.
