It might happen if some of the cloud physics parameters, which determine the growth by condensation, are given unrealistic values or if the droplet radius is extremely small. || |

Otherwise, inconsistencies in the flow forcing would occur. The u/v_profile mechanism is typically used for wind-tunnel applications, where Coriolis force is neglected. || |
