| Zusammenfassung |
| Intense precipitation events are often associated with strong convective phenomena in the atmosphere.
A deeper understanding of how microphysics affects the spatial and temporal variability of convective processes
is relevant for many hydro-meteorological applications, such as the estimation of rainfall using remote sensing
techniques and the ability to predict severe precipitation processes.
In this paper, high-resolution simulations (0.1-1 km) of an atmosphere in radiative-convective equilibrium are
performed using the Weather Research and Forecasting (WRF) model by prescribing different microphysical
parameterizations.
The dependence of fine-scale spatio-temporal properties of convective structures on microphysical details are
investigated and the simulation results are compared with the known properties of radar maps of precipitation
fields. We analyze and discuss similarities and differences and, based also on previous results on the dependence of precipitation statistics on the raindrop terminal velocity, try to draw some general inferences. |
