Impact of Stochastically Perturbed Terminal Velocities on Convective-Scale Ensemble Forecasts of Precipitation

Table 2

Configurations for the Alabama case.

Experiment name	Microphysics	R (rr)	R (rs)	R (rh)	Spatial scale (km)	Temporal scale (h)
LINens	Lin	1.0	1.0	1.0	N/A	N/A
MY2ens	MY2	1.0	1.0	1.0	N/A	N/A
LINprt_ref	Lin	0.8–1.0	0.1–0.5	0.2–0.7	100	1
MY2prt_ref	MY2	0.75–1.25	0.75–1.25	0.75–1.25	100	1

For the resampling function R (·), l_min and l_max are listed. In LINens and MY2ens, the value of R (·) is forced to be a constant of 1.0 so that terminal velocities are not perturbed.
