| Zusammenfassung |
| We use a one-dimensional cloud electrification model, called Explicit Microphysics
Thunderstorm Model (EMTM), to interpret the non-inductive electrification processes and to
find quantitative relationships between the simulated electrical activity and microphysical
properties in convective clouds. For selected case studies, the simulated lightning activity is
compared with LINET ground network lightning data, used as ground truth, to
verify the ability of the model to reproduce electrical activity consistent with the
observations. Analyzing the output from the model explicit microphysics scheme in
conjunction with the simulated electrical activity, a correlation is found between some
key microphysics properties of the cloud and the corresponding lightings. These
relationships constitute the foundation for future applications where the EMTM
model output can be used to infer cloud properties based on lighting observations. |
