Variation of the fraction of realizations with free convection \(N_{\text{convection}}\) with horizontal correlation length \(\text{cl}_\text{h}\) for two different \(\text{cl}_\text{v}\). Ensembles with \(\text{cl}_\text{v} = 100\,\hbox {m}\) show a significantly stronger decrease in convecting realizations, compared to ensembles with \(\text{cl}_\text{v} = 150\,\hbox {m}\)
