Recent applications

The two-moment cloud microphysics scheme has been used within the framework of the HD(CP)² (High Definition Clouds and Precipitation for Climate Prediction, ​http://www.hdcp2.eu) project to produce LES simulation data for the evaluation and benchmarking of ICON-LES (Dipankar et al., 2015). Figure 8 contains a snapshot from such a benchmark simulation, where three continuous days were simulated. The figure shows the simulated clouds including precipitation events on 26 April 2013 during a frontal passage. Moreover, cloud microphysics have been recently used for investigations of shadow effects of shallow convective clouds on the ABL and their feedback on the cloud field (Gronemeier et al. 2016).

Figure 8: Snapshot of the cloud field from a PALM run for three continuous days of the HD(CP)² Observational Prototype Experiment. Shown is the 3-D field of q_c (white to gray colors) as well as rain water (q_r > 0, blue) on 26 April 2013. The simulation had a grid-spacing of 50 m on a 50 x 50 km² domain. Large-scale advective tendencies for θ_l and q were taken from COSMOE-DE (regional model of German Meteorological Service, DWD) analyses.
