Short summary
We provide various statistical properties for the stochastic model of eddy hopping, which is a novel cloud microphysical model that accounts for the effect of the supersaturation fluctuation at unresolved scales on the growth of cloud droplets and on spectral broadening in a turbulent cloud. Our results indicate that the model can be improved to have better fidelity to the reference data and to require less computational cost.
