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

Figure 1

Forecast frequency distribution (%) of the resampled samples using either function R(·) or function Log₂. The l_min, l_mid, and l_max are 0.5, 1.0, and 2.0, respectively. The sample size is 50000, and the initial samples followed the Gaussian distribution with a zero mean and an STD of 1.0. For function Log₂, the initial samples within ±1 were used.
